Residual current circuit breaker with overcurrent protection KZS-2M A C32/0.03 002173227

Reliable protection of electrical installations

The KZS-2M residual current circuit breaker with overcurrent protection is a comprehensive solution ensuring the protection of people and equipment in electrical installations. It protects against electric shock, short circuits and overloads, making it an indispensable element of every modern installation. The device is designed for use in TN-S, TN-C-S, TT and IT networks where the neutral and earth conductors are separated.

Functionality and technical parameters

The KZS-2M circuit breaker combines the functions of an overcurrent and residual current circuit breaker, allowing for compact and effective circuit protection. The rated current of the device is 32A, and its tripping characteristic is C – this ensures a quick response to overloads, but also allows for short-term current surges, e.g. during engine starting. The rated residual current at 0.03A (sensitivity A) guarantees effective protection against electric shock. The short-circuit breaking capacity is 10kA, which confirms its reliability in emergency situations.

The design of the circuit breaker has been designed for easy installation and use. A width of 2 modules allows for efficient use of space in the distribution board. The ability to connect wires with a cross-section from 1 to 25 mm² ensures compatibility with various types of installations. Additionally, the circuit breaker has an IP20 degree of protection, which protects it from accidental contact with live conductive parts.

Comfort of use and safety

Equipped with a test button to allow regular checking of the residual current circuit breaker's functionality. The contact position indicator makes it easy to identify the device status (ON/OFF). Secured terminals minimize the risk of accidental contact with live parts. The terminal design allows the use of insulated busbars on both the upper and lower terminals. The ability to seal the lever provides additional protection against unauthorized switching on or off of the device.
