Overcurrent circuit breaker with residual current device 1+N-pole PKNM-10/1N/B/003-MW 236067

Safety and Reliability in Your Electrical Installation

This Eaton PKNM-10/1N/B/003-MW residual current circuit breaker (RCCB) is a key element ensuring protection of electrical circuits in residential and commercial buildings. Designed with user safety in mind, it effectively protects against the effects of overloads, short circuits, and electric shock. Its two-pole design (1+N) provides comprehensive protection, disconnecting both phase and neutral simultaneously, which increases safety in the event of a failure.

Functionality and Technical Parameters

The circuit breaker is characterized by a rated current of 10A and a B characteristic, which means it is ideal for protecting lighting and socket circuits. The B characteristic ensures fast tripping during overloads, but allows for short-term current surges, typical of starting devices with motors – pumps, fans or refrigerators. The rated short-circuit breaking capacity Icn at 10 kA guarantees effective disconnection of the circuit in the event of a serious failure. Additionally, the built-in residual current module with a sensitivity of 0.03A (type AC) protects against dangerous leakage currents to earth.

• Versatile application: ideal for protecting lighting circuits, socket circuits and electrical devices with lower power.
• Two-pole disconnection: provides full protection by disconnecting phase and neutral simultaneously.
• Leakage current protection: built-in residual current module minimizes the risk of electric shock.
• Compact dimensions: 2 module width makes it easy to install in electrical panels with limited space.
• Wide operating temperature range: from -25°C to 40°C allows use in various environmental conditions.
• Suitable for conductors: accepts both solid and stranded conductors with a cross-section from 1 mm² to 25 mm².

Installation and Compliance with Standards

The circuit breaker is designed for easy mounting on a TH35 rail. It meets the requirements of EN 61009-1 and EN 61009 standards, which confirms its high quality and safety of use. The IP20 degree of protection provides protection against finger contact, but does not protect against the action of water – therefore, the circuit breaker should be mounted in dry and well-ventilated places. Energy limitation class 3 indicates its ability to withstand short-circuit energy without damage.
