Residual Current Device (RCD) IDK-40-4-30-A 40A 4-pole 30mA type A A9Z01440

Safety and Reliability in Your Electrical Installation

This four-pole residual current circuit breaker (RCCB) with a rated current of 40A and a tripping current of 30mA, type A, is a key element ensuring the protection of people and equipment in electrical installations. Designed to work with AC circuits, it effectively reacts to both sinusoidal and pulsating DC currents, minimizing the risk of electric shock. Its robust construction and high short-circuit strength (10kA) guarantee reliable operation even in harsh conditions.

Installation and Application – for Professionals and Demanding Users

Mounting on a DIN rail is quick and intuitive, which translates to time savings during installation. A width of 4 modules allows for efficient use of space in the distribution board. This circuit breaker is used both in residential and commercial buildings where high efficiency of shock protection is required. The cross-section of the connectable solid wire up to 35mm² and stranded wire up to 25mm² ensures compatibility with different types of cables.

Key Features and Benefits

• High Protection: Rated residual current of 0.03A (30mA) ensures a quick response to leakage currents, protecting against electric shock.
• Versatility: Type A guarantees correct operation with various types of loads, including electronic devices.
• Robust Construction: Impact current resistance of 0.25kA and rated insulation voltage Ui 440V ensure long-lasting and trouble-free operation.
• Easy Installation: Mounting on a DIN rail and double terminals from below (rail + wire) facilitate and speed up installation.
• Convenience: Serrated terminals increase the certainty of wire connection, and the "T" test button allows for regular checking of the circuit breaker's functionality (recommended once every six months for the first 7 years of use).
• Optimized Wiring: Placement of the N conductor on the left side facilitates wiring with overcurrent circuit breakers – particularly appreciated by installers.
• Wide Compatibility: Additional equipment options expand the functionality of the device.
• Reliability Confirmed by Standards: Compliance with relevant standards ensures safety and high product quality.
• Energy Saving: Power losses are only 3.6W, which translates to lower energy consumption in the installation.
