Residual current circuit breaker with overcurrent protection KZS-2M A B6/0.03 002173201

Safety and protection in your electrical installation

Residual current circuit breaker with overcurrent protection KZS-2M A B6/0.03 is a reliable device that combines protection against electric shock and protection against overloads and short circuits. It is a key element of every modern electrical installation, ensuring the safety of people and equipment. Thanks to its compact size (only 2 modules wide) it is easy to install in a distribution board.

Functionality and application

The device is intended for use in circuits with a voltage of 230V and a rated current of 6A. The B tripping characteristic provides a quick response to current increase, protecting against the effects of short circuits and overloads, while allowing for trouble-free starting of devices with motors that generate momentary current surges. The rated residual current of 0.03A (sensitivity A) guarantees effective protection against electric shock in the event of insulation failure. The circuit breaker is used in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors may be separated or combined.

Construction and characteristics

The KZS-2M A B6/0.03 circuit breaker is distinguished by its solid construction and high quality workmanship. It has a degree of protection IP20, which means protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm. The connection terminals allow connection of wires with a cross-section from 1 to 25 mm², both solid and stranded. Additionally, the circuit breaker is equipped with a test button to check its functionality and a contact position indicator, which facilitates identification of the device status (ON/OFF). The possibility of sealing the lever provides additional protection against unauthorized disconnection. The rated short-circuit breaking capacity is 10kA, which ensures a high level of safety in the event of a short circuit in the installation.
