Residual current circuit breaker with overcurrent protection KZS-2M AC C32/0.03 002173127

Residual Current Device with Overcurrent Protection – protection and safety in one

This device combines the functions of a Residual Current Device (RCD) and a Miniature Circuit Breaker (MCB), providing comprehensive protection for electrical circuits. It protects against electric shock, short circuits and overloads, making it an indispensable element of any electrical installation. This is particularly important in residential premises, offices and public buildings.

Design features and application

The KZS-2M AC C32/0.03 circuit breaker is designed to operate in TN-S, TN-C-S, TT and IT networks where the neutral and earth conductors may be separated. Its compact design (2 module width) allows for easy installation in electrical distribution boards. It is intended for protecting circuits with a rated current of 32A. Characteristic C provides a delayed response to short-term overloads, which is important for devices with motors or other inductive loads – it reacts more slowly to short current surges, therefore tolerates the starting of devices with a motor well. The rated differential current of 0.03A ensures a quick response in the event of a leakage current to earth.

Advantages and benefits

• Multifunctionality: Combining RCD and MCB in one device saves space in the distribution board and simplifies installation.

• Safety: Provides protection against electric shock and damage to the installation caused by short circuits and overloads.

• Versatility: Suitable for use in various types of electrical networks (TN-S, TN-C-S, TT, IT).

• High reliability: Made of high-quality materials, guarantees long-lasting and trouble-free operation.

• Easy testing: Has a "Test" button to allow regular checking of the device's functionality.

• Clear indication: Contact position indicator makes it easy to identify the device's status (ON/OFF).

• Touch protection: Terminal design minimizes the risk of accidental contact with live parts.

• Expandability: Possibility of mounting auxiliary contacts PS KZS-2M/4M for remote signaling of the device's status.

The rated current is 32A, which means the maximum current the circuit breaker can conduct without damage. Characteristic C provides a delayed response to short-term overloads – ideal for loads with motors or other inductive components. The rated differential current is 0.03A, which guarantees a quick response to leakage current to earth. The rated breaking capacity is 15 kA – the maximum short-circuit current that the circuit breaker can safely interrupt. The compact width of 2 modules makes it easy to install in tight electrical distribution boards.

The KZS-2M AC C32/0.03 circuit breaker is a solid and reliable solution for ensuring the safety and protection of electrical installations for both professionals and end users. Its versatility and ease of installation make it an ideal choice for a wide range of applications.
