Residual current circuit breaker 6kA type A HNC-40/2/003-A 194685

Safety and reliability in your electrical installation

The Eaton HNC-40/2/003-A residual current circuit breaker (RCCB) is a key element ensuring the protection of people and equipment in electrical installations. Designed for residential and commercial buildings, it effectively protects against electric shock, fire and damage to equipment. Its solid construction and high quality workmanship guarantee reliable operation for a long time.

Functionality and technical parameters

This two-pole residual current circuit breaker with a rated current of 40A and a sensitivity of 0.03A (type A) provides protection against alternating and pulsating leakage currents. The rated short-circuit making capacity of 6kA ensures effective disconnection of the circuit in the event of a short circuit. Mounting on a DIN TH-35 rail is quick and easy, and the compact dimensions (2 modules wide) allow for efficient use of space in the distribution board. Equipped with a lock, it prevents accidental switching on or off.

• Protection against electric shock: Reacts to leakage currents, minimizing the risk of electric shock.
• Fire protection: Reduces the risk of fire caused by short circuits or insulation damage.
• Wide range of applications: Ideal for installation in homes, apartments, offices and other commercial facilities.
• Compatibility with DIN rails: Allows easy mounting on standard TH-35 rails.
• Double terminals: Both screw and busbar terminals facilitate the connection of wires with a cross-section from 1.5 mm² to 35 mm².
• Recommended testing every 6 months: Regular tests help maintain the full efficiency of the device and ensure safe operation.

Additional information for professionals

The HNC-40/2/003-A circuit breaker is characterized by high surge current resistance (0.25 kA) and a rated insulation voltage Ui of 440V. The ability to add additional accessories, such as auxiliary contacts or releases, increases the functionality of the device and allows it to be adapted to the specific needs of the installation. Compliance with IEC/EN 61008 standards ensures a high level of safety and reliability. Suitable for operation in ambient temperatures from -25°C to 60°C and has a protection degree of IP20. Remember the need to use appropriate preliminary protection - max. 63A gL/gG for short circuits and 25A gL/gG for overloads.
