The Schneider Electric Easy9 EZ9F53225 Miniature Circuit Breaker (MCB) is a premium 2-pole thermal-magnetic circuit breaker designed to protect low-voltage AC electrical installations against overloads and short circuits. Rated at 25A with a 3kA breaking capacity, it is ideal for residential, commercial, and light industrial distribution applications requiring reliable dual-pole protection and isolation.
As part of the trusted Schneider Electric Easy9 range, the EZ9F53225 features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as lighting systems, socket outlets, air conditioning units, pumps, small motors, and general-purpose electrical equipment. Its thermal-magnetic trip unit combines accurate overload protection with rapid short-circuit interruption to maximise electrical safety.
The breaker provides a 3kA rated breaking capacity (Icu) at 400VAC and fully complies with SANS 60947-2, ensuring dependable protection for modern electrical installations. It also features a 500V insulation voltage (Ui), 4kV impulse withstand voltage (Uimp), and Limitation Class 3, offering excellent insulation performance and protection against transient overvoltages.
Its compact 36mm-wide housing occupies only 4 DIN modules and installs quickly using a clip-on mounting system for 35mm DIN rails. A built-in contact position indicator provides clear visual confirmation of breaker status, while robust tunnel-type terminals accept 1mm to 35mm rigid or flexible conductors for simple installation.
Built for long-term reliability, the Schneider Easy9 EZ9F53225 offers 10,000 mechanical operations and 4,000 electrical operating cycles, making it a dependable solution for protecting electrical circuits in demanding environments.
