The Schneider Electric Easy9 EZ9F53220 Miniature Circuit Breaker (MCB) is a dependable 2-pole thermal-magnetic circuit breaker designed to provide reliable protection against overloads and short circuits in low-voltage AC electrical installations. Rated at 20A with a 3kA breaking capacity, this MCB is ideal for residential, commercial, and light industrial distribution systems where dual-pole protection and isolation are required.
As part of the trusted Schneider Electric Easy9 range, the EZ9F53220 features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as lighting systems, socket outlets, air conditioners, pumps, small motors, and other general-purpose electrical loads. Its thermal-magnetic trip unit combines accurate overload protection with fast short-circuit interruption for enhanced electrical safety.
The breaker delivers a 3kA rated breaking capacity (Icu) at 400VAC and complies with SANS 60947-2, ensuring dependable protection in modern electrical installations. It also features a 500V rated insulation voltage (Ui) and 4kV impulse withstand voltage (Uimp), providing excellent insulation and protection against transient overvoltages.
Designed for easy installation, the EZ9F53220 clips securely onto a 35mm DIN rail and occupies only 4 DIN modules (36mm width), making it suitable for compact distribution boards. A built-in contact position indicator allows quick visual confirmation of the breaker status, while durable tunnel-type terminals accommodate rigid and flexible conductors for simple wiring.
Manufactured by Schneider Electric, the Easy9 EZ9F53220 offers long-lasting performance with 10,000 mechanical operations and 4,000 electrical operating cycles, making it an excellent choice for dependable everyday circuit protection.
