The Schneider Electric Easy9 EZ9F53216 Miniature Circuit Breaker (MCB) is a reliable 2-pole thermal-magnetic circuit breaker designed to protect low-voltage AC electrical installations against overloads and short circuits. Rated at 16A with a 3kA breaking capacity, it is ideal for residential, commercial, and light industrial electrical distribution systems where simultaneous protection and isolation of both poles is required.
Part of the trusted Schneider Electric Easy9 range, the EZ9F53216 features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as lighting, socket outlets, HVAC equipment, pumps, small motors, and general-purpose electrical loads. Its thermal-magnetic trip mechanism combines precise overload protection with fast short-circuit interruption for enhanced electrical safety.
With a 3kA rated breaking capacity (Icu) at 400VAC, the breaker complies with SANS 60947-2, ensuring dependable performance and safe operation. It also features a 500V rated insulation voltage (Ui), 4kV impulse withstand voltage (Uimp), and Limitation Class 3, providing excellent protection against electrical transients and fault conditions.
The compact 36mm-wide housing occupies 4 DIN modules (4 × 9mm pitches) and mounts quickly onto a 35mm DIN rail using a clip-on mechanism. A built-in contact position indicator provides a clear visual indication of the breaker status, while durable tunnel-type terminals accommodate 1mm to 25mm rigid or flexible conductors for simple installation and maintenance.
Designed for long service life with 10,000 mechanical operations and 4,000 electrical operating cycles, the Schneider Easy9 EZ9F53216 delivers dependable circuit protection for a wide variety of AC power distribution applications.
