Your control panel production schedule requires 200 green terminal blocks and 150 barrier terminal blocks next week. You contact suppliers. The responses: “8-week lead time from China,” “12-week import lead time,” “we can check availability and get back to you.” Your production can’t wait two months for terminal blocks.
Stock availability matters when production schedules operate on days, not months. OX Connections maintains comprehensive stock of green terminal blocks and barrier terminal blocks across multiple pitch options and current ratings in our India warehouse—available for immediate shipment to support your production requirements.
Green Terminal Blocks: Comprehensive Stock Range
Green terminal blocks (ground/earth terminal blocks) provide organized grounding connections in control panels, distribution equipment, and electrical assemblies. The green or green-yellow housing provides visual identification for safety grounding circuits, essential for proper electrical installation practices and safety compliance.
Pitch Options Available Ex-Stock:
5.08mm Pitch Green Terminal Blocks: Standard pitch for general industrial applications providing good balance between connection density and current capacity. Wire capacity typically 0.5-4mm². Common in control panels, industrial equipment, and electrical distribution. PCB mount and hanging (chassis mount) types available.
3.81mm Pitch Green Terminal Blocks: Compact pitch for higher connection density on PCBs where board space matters. Wire capacity typically 0.5-2.5mm². Used in space-constrained control boards, compact industrial modules, and applications requiring multiple ground connections in limited area.
7.62mm Pitch Green Terminal Blocks: Larger pitch for higher current ground connections and larger wire gauges. Wire capacity typically 1-6mm². Applications include main ground distribution, chassis grounding for high-power equipment, and ground collection points in power distribution panels.
7.5mm Pitch Green Terminal Blocks: Alternative larger pitch option for applications requiring specific spacing or compatibility with existing panel layouts. Similar wire capacity and current handling to 7.62mm pitch.
Terminal Block Series 126, 127, 128, 129:
Standard terminal block series designations covering various configurations, pole counts, and current ratings. These series numbers represent specific mechanical and electrical specifications. Contact our technical team for detailed specifications on specific series numbers matching your requirements.
PCB Type vs Hanging Type:
PCB Mount Green Terminal Blocks: Solder directly to printed circuit boards, providing secure mechanical mounting and electrical connection. Used in control boards, power supplies, and equipment where terminal blocks mount on PCBs. Through-hole solder termination ensures reliable PCB connection.
Hanging Type (Chassis Mount): Mount directly on DIN rail, panel surfaces, or chassis using screws or DIN rail clips. Used in control panels, junction boxes, and electrical enclosures where terminal blocks don’t mount on PCBs. Provides flexible mounting options for panel wiring applications.
All green terminal blocks in OX stock include:
- RoHS compliance certification
- UL certification where applicable
- Technical datasheets with specifications
- Test reports available upon request
- Immediate availability from India warehouse
Barrier Terminal Blocks: High Current Range Ex-Stock
Barrier terminal blocks provide physical separation between connection poles, preventing accidental wire contact and providing electrical isolation between circuits. The barrier design offers enhanced safety and clearance for high-current or mixed-voltage applications.
High Current Barrier Terminal Blocks Available:
11mm Pitch Barrier Terminal Blocks:
Current ratings from 10A to 25A depending on specific configuration and wire gauge. Wire capacity supports larger conductors required for higher current applications. The 11mm spacing provides adequate clearance for higher current contacts and larger wire terminations.
Applications: Motor connections, power distribution, high-current control circuits, main power feeds in industrial equipment.
12mm Pitch Barrier Terminal Blocks:
Similar current range (10-25A) with slightly larger spacing. The 12mm pitch provides additional clearance beneficial for high-voltage applications or installations requiring extra safety margin between circuits.
Applications: High-power equipment, mixed voltage systems, applications requiring enhanced electrical clearance, safety-critical installations.
Current Rating Options:
Barrier terminal blocks available in 10A, 15A, 20A, and 25A current ratings. Select appropriate rating based on circuit current requirements and wire gauge. Proper current rating selection ensures terminal blocks operate within temperature limits and maintain long-term reliability.
Key Features:
Physical barriers between poles prevent wire bridging during installation and eliminate accidental contact between adjacent circuits. Important for safety compliance and preventing installation errors.
Higher current capacity compared to standard terminal blocks due to larger contacts and wire capacity. Essential for power distribution, motor connections, and high-current control circuits.
Both PCB mount and DIN rail mount configurations available depending on installation requirements.
All barrier terminal blocks include:
- RoHS compliance documentation
- UL certification
- Current rating specifications and temperature rise data
- Wire gauge compatibility information
- Complete technical datasheets
- Test reports upon request
Stock Availability: The OX Advantage
Immediate Availability from India Warehouse:
We maintain substantial stock of green and barrier terminal blocks across pitch options, current ratings, and mounting types. Stock inventory means lead times measured in days, not weeks or months. When your production schedule operates on tight timelines, component availability determines whether you ship on schedule or explain delays to customers.
Why Stock Matters:
Import lead times from China or Taiwan typically run 8-12 weeks for terminal blocks. Ocean freight, customs clearance, inland transportation—the supply chain adds months between order placement and delivery. If you’re building control panels or electrical equipment on production schedules measured in weeks, you can’t wait three months for terminal blocks.
Local stock in India eliminates import delays. Order today, ship tomorrow, receive within days depending on location. Your production continues without component shortages stopping assembly lines.
Comprehensive Range Reduces Supplier Count:
Instead of sourcing green terminal blocks from one supplier, barrier blocks from another, and different pitches from a third supplier, OX stocks the complete range. One purchase order, one invoice, one delivery—simplified procurement supporting your production efficiency.
Volume Stock for OEM Production:
We stock quantities supporting both prototype requirements (tens of pieces) and production volumes (hundreds or thousands). OEMs building multiple control panels or electrical assemblies monthly can rely on consistent stock availability without minimum order quantities creating inventory problems.
Certifications and Documentation Support
RoHS Compliance:
All terminal blocks in OX stock comply with European RoHS directives. RoHS certification documentation provided with orders supports your compliance processes when building equipment for export markets or customers requiring environmental compliance.
UL Certification:
UL-recognized terminal blocks available across the range. UL certification simplifies your equipment certification process when selling to markets requiring UL listing or to customers specifying UL-recognized components.
Test Reports:
Product test reports available documenting electrical performance, temperature rise testing, mechanical retention testing, and other critical specifications. Test reports support your quality processes and customer requirements for component validation.
Technical Datasheets:
Complete datasheets provided covering:
- Mechanical dimensions for PCB layout or panel mounting
