Circuit breakers 2A

2A MCB for Precision Circuit Protection in Control and Signal Systems

A 2a mcb (miniature circuit breaker) is designed for precise overcurrent protection in sensitive control, automation, and signaling circuits. Unlike high-current devices, the 2a circuit breaker is used where the load is minimal but stable operation is critical — for example, in relay controls, BMS systems, and fire alarm panels.

At Bank of Lamps, we supply certified 2a mcb units from top EU brands for integration into DIN-based enclosures across commercial and industrial sites.

Where 2A Circuit Breakers Are Used

• Building Management Systems (BMS) — powering sensors, thermostats, and actuators
   
• Relay and PLC Panels — isolating low-voltage logic or feedback loops
   
• Security and Access Control — powering card readers, door controllers, and intercoms
   
• Fire Alarm Systems — ideal for circuits feeding sounders or addressable heads
   
• Telecom and Network Cabinets — where fused DC loads are not preferred
   

In these contexts, mcb 2a breakers prevent localized overloads from affecting the rest of the control infrastructure.

2A MCB Brands and Variants in Stock

We maintain availability across DIN-rail 2a circuit breaker models from trusted OEMs:

• Schneider Electric Acti9 iC60N — B-curve / C-curve options, 6kA
   
• ABB S201/S202 series — compact single and multi-pole configurations
   
• Eaton FAZ-B2 / FAZ-C2 — quick-connect terminals, IEC/EN 60898-1
   
• Hager MBN & MBS — available in B and C tripping curves for control applications
   
• Legrand TX³ / DX³ — clean labeling and auxiliary integration slots
   

Most variants feature 1P (single pole) for compact mounting, but we also stock 2P/3P where circuit separation is required. Breaking capacity typically 6–10 kA at 230/400V AC.

Technical Specs and Wiring Guidelines

• DIN-rail compatibility: standard 35 mm rail, clip-in
   
• Conductor size: 1.5–4 mm² solid or stranded (Cu)
   
• Terminal tightening torque: ~2 Nm typical
   
• B or C curve: B for ultra-sensitive, C for moderate inductive loads
   
• Coordination: often paired with control relays or surge protection modules
   

We provide detailed wiring instructions, datasheets, and manufacturer certifications for every stocked SKU.
