Overcurrent circuit breaker with residual current device 1+N-pole PKNM-10/1N/C/003-A-MW 236082

Safety and reliability in one device

The PKNM-10/1N/C/003-A-MW overcurrent circuit breaker with residual current device is a comprehensive solution for protecting electrical installations from the effects of overloads, short circuits and electric shock. The device combines the function of a type C overcurrent circuit breaker and a residual current device, providing double protection for both the installation and users. This is a key element of every modern electrical installation, guaranteeing safe and reliable operation.

Functionality and technical parameters

This two-pole (1+N) circuit breaker with a rated current of 10A is characterized by a high short-circuit breaking capacity – up to 10 kA. Characteristic C provides delayed tripping during short-term overloads, which is particularly important when operating devices with motors or other elements generating high starting current. Additionally, the built-in residual current device with a sensitivity of 30 mA (0.03 A) effectively protects against electric shock in the event of insulation failure. The rated insulation voltage Ui is 440 V, ensuring safety in standard installations. The device occupies a width of 2 modules, making it easy to mount in electrical distribution boards. The IP20 degree of protection protects against finger contact. Suitable for operation in ambient temperatures from -25°C to 40°C, it allows connection of multi-strand and solid core wires with a cross-section from 1 mm² to 25 mm². Compliance with EN 61009-1 standards ensures a high level of safety and reliability.

Installation and application

The PKNM-10/1N/C/003-A-MW circuit breaker is designed for mounting on TH-35 rails. Its compact size and ease of installation make it ideal for both new installations and modernization of existing ones. It finds application in lighting circuits, socket circuits and when powering electrical devices requiring short-circuit and personal protection. Thanks to the simultaneous disconnection of the N pole, it increases the safety of the entire installation.
