About the Easy9 MCB
About the Easy9 MCB
The Schneider Electric EZ9F34440 is a 4-pole 40A miniature circuit breaker from the Easy9 series, rated at 400V AC with a breaking capacity of 4500A — designed for reliable overcurrent and short-circuit protection in residential, commercial, and light industrial distribution boards. The Easy9 MCB mounts directly on standard DIN rail, offering a compact modular form factor that simplifies panel assembly and maintenance. With a net weight of 0.492 kg, this 4P unit is engineered for straightforward, cost-effective installation in final distribution applications.
Applications & Use Cases
- Residential distribution boards: Final circuit protection for domestic consumer units requiring a compact, reliable 4-pole MCB.
- Commercial installations: Protection of three-phase + neutral circuits in offices, retail units, and light commercial premises.
- Light industrial panels: Overcurrent and short-circuit protection for modular distribution boards in workshops and small manufacturing environments.
- DIN rail panel building: Ideal for panel builders seeking a cost-effective, space-saving modular circuit breaker that integrates cleanly with standard 35mm DIN rail accessories.
