Residual current circuit breaker with overcurrent protection KZS-2M A C10/0.03 002173222

Residual Current Device with Overcurrent Protection KZS-2M is a reliable device used to protect people and electrical installations. It provides protection against electric shock, both in the case of direct and indirect contact, and also protects against the effects of insulation damage. Additionally, it protects circuits against overloads and short circuits – just like standard overcurrent circuit breakers do.

This model, with a rated current of 10A and characteristic C, is particularly recommended for protecting circuits with receivers generating inrush currents during start-up, such as motors. Characteristic C allows it to react more slowly to short current surges, which prevents unnecessary tripping. The rated differential current of 0.03A (sensitivity A) provides effective protection against dangerous leakage currents.

Construction and mounting

The KZS-2M circuit breaker occupies 2 module widths, which makes it easy to install in standard electrical distribution boards. It has a protection degree of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The cross-section of the connected wire can range from 1 to 25 mm², for both solid and stranded wires, which provides great flexibility during installation. Additionally, the circuit breaker has a simultaneously disconnecting N pole, which increases safety.

Application and compliance with standards

This circuit breaker is intended for use in TN-S, TN-C-S, TT and IT networks. It meets the requirements of EN 61009 standard and has a rated short-circuit breaking capacity of 10 kA. The device operates at a rated voltage of 230V and a frequency of 50 Hz. It is a universal solution for both professional installers and end-users looking for reliable electrical protection in their home or company.
