Overcurrent circuit breaker with residual current device 1+N-pole PKNM-10/1N/C/003-MW 236077

Safety and reliability in one – Residual Current Device with overcurrent protection

This circuit breaker combines short-circuit and residual current protection, providing comprehensive safety for electrical installations. Model PKNM-10/1N/C/003-MW is an ideal solution for both installers and end-users who value reliability and ease of installation. The use of characteristic C makes the device cope well with shock loads, such as starting motors or transformers.

Functionality and technical parameters

The circuit breaker is designed to operate in installations with a rated voltage of 230V and a rated current of 10A. Its construction includes a protective and neutral pole (1+N), which increases the range of applications. The rated short-circuit breaking capacity Icn is 10 kA, guaranteeing effective protection against the effects of overloads and short circuits. Additionally, the built-in residual current device with a sensitivity of 30mA (type AC) protects users from electric shock.

• Overload protection: Characteristic C provides delayed tripping with short-term overloads, preventing unnecessary tripping of the device when starting receivers.
• Residual current protection: 30mA sensitivity ensures a quick response to leakage currents, minimizing the risk of electric shock.
• Rated breaking capacity: 10 kA guarantees effective disconnection of the circuit in the event of a short circuit.
• Width: Occupies only 2 modules in the switchboard, allowing for optimal use of space.
• Wire cross-section: The possibility of connecting wires with a cross-section from 1 to 25 mm², both solid and stranded, provides installation flexibility.

Installation and compliance with standards

The PKNM-10/1N/C/003-MW circuit breaker is designed for mounting on a TH35 rail (standard mounting rail in switchboards). The degree of protection IP20 provides protection against accidental contact, but does not protect against water ingress. The device meets the requirements of EN 61009-1 standard and has energy limitation class 3, which confirms its high quality and safety of use. The ambient temperature in operating conditions is in the range of -25°C to +40°C, which allows its use in various environmental conditions.
