Schneider Easy9 EZ9F53116 1 Pole 16A C Curve MCB 3kA Circuit Breaker

The Schneider Electric Easy9 EZ9F53116 Miniature Circuit Breaker (MCB) is a high-quality 1-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, this compact MCB is ideal for residential, commercial, and light industrial distribution systems.

As part of the trusted Schneider Electric Easy9 range, the EZ9F53116 features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as socket outlets, lighting circuits, small motors, air conditioning controls, and general-purpose electrical loads. Its thermal-magnetic trip mechanism provides accurate overload protection while ensuring rapid interruption of fault currents.

The breaker offers a 3kA rated breaking capacity (Icu) at 230VAC and complies with SANS 60947-2, ensuring dependable protection and safe operation. With a 500V insulation voltage (Ui), 4kV impulse withstand voltage (Uimp), and Limitation Class 3, it delivers excellent performance under demanding electrical conditions.

Designed for easy installation, the EZ9F53116 clips securely onto a 35mm DIN rail and occupies only 2 x 9mm module spaces (18mm width). It features a clear contact position indicator, durable tunnel-type terminals accommodating conductors from 1mm to 25mm , and is engineered for a long service life with 10,000 mechanical and 4,000 electrical operating cycles.

The Schneider Easy9 EZ9F53116 is a reliable and cost-effective solution for protecting branch circuits in modern electrical distribution boards.
