Residual current circuit breaker with overcurrent protection KZS-2M AC B32/0.03 002173107

Residual Current Device with Overcurrent Protection – Comprehensive Installation Protection

This device combines the functions of a Residual Current Device (RCD) and an overcurrent circuit breaker, providing comprehensive protection for electrical circuits. It protects against electric shock, short circuits and overloads, making it an indispensable element of a safe electrical installation. This is particularly important in places where there is a risk of direct or indirect contact with live parts.

Construction and application

The KZS-2M AC B32/0.03 circuit breaker is designed for use in TN-S, TN-C-S, TT and IT networks where the neutral and earth conductors are separated. Its design allows for mounting on a TH35 rail, and the power connection is possible from both the top and the bottom, which facilitates installation. Thanks to its compact dimensions (2 module width) it takes up little space in the distribution board. The test button allows for regular checking of the device's functionality, and the contact position indicator helps to quickly identify the status of the circuit breaker.

Key features and benefits

• Protection against electric shock: The rated differential current of 0.03 A ensures a quick response to leakage currents, minimizing the risk of electric shock.
• Protection against overload and short circuit: The B tripping characteristic guarantees effective protection against overloads and short circuits in the circuit. This means that the circuit breaker reacts quickly to sudden current increases, protecting devices and the installation from damage.
• Versatility: Suitable for operation with AC 230 V voltage and 50 Hz frequency – standard parameters for most domestic and industrial installations.
• High breaking capacity: The rated short-circuit breaking capacity of 10 kA ensures effective disconnection of the circuit in the event of a short circuit with high power.
• Safety of use: Terminal protection against contact under voltage increases safety during installation and operation.
• Compatibility: The possibility of mounting auxiliary contacts PS KZS-2M/4M allows for expanding the functionality of the circuit breaker with additional control signals.
• Connection flexibility: The possibility of connecting wires with a cross-section from 1 to 25 mm², both solid and stranded, provides a wide range of applications.

The KZS-2M AC B32/0.03 circuit breaker is a solid and reliable device that will meet the expectations of both professional installers and end-users looking for comprehensive protection for their electrical installation. Its versatility and high quality of workmanship guarantee long-lasting and trouble-free operation.
