Schneider Easy9 EZ9F53363 3 Pole 63A C Curve MCB 3kA Circuit Breaker

The Schneider Electric Easy9 EZ9F53363 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. With a 63A rated current and 3kA breaking capacity, this MCB is ideal for residential, commercial, and light industrial distribution systems requiring dependable protection and isolation of three-phase circuits.

Part of the trusted Schneider Electric Easy9 range, the EZ9F53363 features a C-curve tripping characteristic, making it ideal for circuits with moderate inrush currents such as three-phase motors, pumps, compressors, HVAC equipment, lighting systems, distribution boards, and general-purpose power circuits. Its thermal-magnetic trip mechanism provides accurate overload protection while rapidly disconnecting circuits during short-circuit faults.

The breaker delivers a 3kA rated breaking capacity (Icu) at 400VAC and complies with SANS 60947-2, ensuring safe and reliable operation in modern electrical installations. It also features a 500V rated insulation voltage (Ui) and is suitable for use as an isolating device, offering dependable performance and enhanced electrical safety.

The compact 3-pole design mounts easily onto a standard 35mm DIN rail, making installation fast and straightforward in distribution boards and electrical panels. Its contact position indicator provides a clear visual indication of breaker status, while high-quality tunnel-type terminals ensure secure cable connections and long-term reliability.

Designed for demanding applications, the Schneider Easy9 EZ9F53363 combines Schneider Electric's proven engineering with robust construction, making it an excellent choice for protecting three-phase circuits in residential, commercial, and industrial environments.
