40A MCB Units for Power-Hungry Loads and Three-Phase Panels

The 40a mcb is designed for circuits with higher continuous loads — such as three-phase HVAC systems, rooftop solar arrays, small commercial kitchens, and EV charging stations. With a solid 6–10 kA breaking capacity and compatibility with modular DIN boards, this breaker class is the preferred option for installers balancing safety, longevity, and compliance.

Bank of Lamps supplies 40a circuit breaker models from verified European brands including ABB, Schneider Electric, Legrand, Hager, ETI, and Doepke. All products ship directly from our 5,100 m² EU warehouse, with reliable logistics across Germany, France, Spain, the Baltics, Benelux, and the UK.

Application Areas for an MCB 40A

An mcb 40a is typically used in:

3-phase HVAC compressors or rooftop ventilation units
Wall-mounted EV chargers and charge hubs (up to 9.6 kW)
Commercial kitchen blocks — including combi ovens or steamers
Distribution boards for industrial tools, lifts, or pumps
Subpanels feeding multiple 16A–32A lines

We offer curve B and C options depending on load profile. C-curve is standard for inductive applications, while B-curve covers resistive installations. Some projects also opt for selective MCBs with 10kA+ capacity when upstream breakers require time-delay selectivity.

Technical Specs and Breaker Options

Most stocked 40a mcb products include:

1P, 1P+N, 3P, 3P+N configurations
Breaking capacities: 6 kA (standard), 10 kA (industrial)
Terminal types: screw, lift-clamp, or push-in
Mounting width: 18 mm (single pole), up to 72 mm (4-pole)
Operating temp: -25°C to +60°C
Conformity: EN 60898-1, IEC 60947-2, CE, RoHS

Top-selling models include:

ABB S203-C40 – 3P, 10kA, robust housing
Hager MBS340C – compact C-curve, tool-free mount
Schneider Electric Acti9 iC60N C40 – auxiliary-ready, wide accessory range
Legrand DX³ C40 – dual terminal format, UL + CE labels
ETI C40/3 – economical option for bulk deployment

All units can be supplied in standalone format or as part of pre-assembled DIN modules.

Why Choose Bank of Lamps for MCB 40A Supply

Over 96 EU-certified brand partnerships
Flexible quantities — from 5 pcs to full board rollout
