Schneider Easy9 EZ9F53332 3 Pole 32A C Curve MCB 3kA Circuit Breaker

The Schneider Electric Easy9 EZ9F53332 Miniature Circuit Breaker (MCB) is a premium 3-pole thermal-magnetic circuit breaker designed to provide reliable protection against overloads and short circuits in three-phase low-voltage AC electrical installations. Rated at 32A with a 3kA breaking capacity, this MCB is ideal for residential, commercial, and light industrial distribution systems requiring dependable three-phase circuit protection.

As part of the trusted Schneider Electric Easy9 range, the EZ9F53332 features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as three-phase motors, pumps, compressors, HVAC equipment, machinery, and general-purpose power distribution. Its thermal-magnetic trip mechanism delivers precise overload protection while rapidly disconnecting circuits during short-circuit faults.

With a 3kA rated breaking capacity (Icu) at 400VAC, the breaker complies with SANS 60947-2, providing dependable protection for modern electrical installations. It also features a 500V rated insulation voltage (Ui), 4kV impulse withstand voltage (Uimp), and Limitation Class 3, ensuring excellent insulation performance and resistance to transient overvoltages.

The compact 54mm-wide housing occupies 6 DIN modules and installs easily onto a standard 35mm DIN rail using a convenient clip-on mechanism. A built-in contact position indicator provides instant visual confirmation of the breaker status, while robust tunnel-type terminals accommodate 1mm to 35mm rigid or flexible conductors for secure and efficient wiring.

Designed for long service life, the Schneider Easy9 EZ9F53332 offers 10,000 mechanical operations and 4,000 electrical operating cycles, making it a reliable solution for protecting three-phase electrical systems.
