Circuit breakers 50A

50A MCB for Heavy-Duty Industrial and Sub-Distribution Panels

The 50a mcb is built for high-load circuits that demand stable performance, thermal endurance, and guaranteed fault disconnection under stress. Whether you're wiring an EV infrastructure panel, powering high-amperage HVAC units, or assembling industrial sub-distribution, the mcb 50a covers the gap between 40A commercial and 63A heavy industrial classes.

Bank of Lamps supplies 50a circuit breaker models from top-tier brands — including ABB, Schneider Electric, ETI, Doepke, Hager, and Legrand — with availability for B-curve, C-curve, and D-curve variants. All products are stocked in our central EU warehouse with real-time dispatch to Germany, Benelux, France, Baltics, Spain, and the UK.

Where a 50A MCB Fits in the System

The 50a circuit breaker is typically used in:

• Secondary panels for EV charge hubs (11–22 kW)
• Motor control centers (MCCs) with pump/compressor lines
• HVAC outdoor units for large residential or mid-scale commercial blocks
• Elevator control circuits
• PV inverter DC protection (where MCBs are allowed under specs)

We stock both 1P+N and 3P+N versions, supporting both single-phase loads and three-phase balance panels. Curves B and C are standard, with D-curve options for high inrush current devices.
