Residual current circuit breaker IDK-25-2-30-AC 25A 2-pole 30mA type AC A9Z05225

Protection and safety in your electrical installation

Residual Current Device (RCD) IDK-25-2-30-AC is a key element ensuring safety in every electrical circuit. The device, catalog number A9Z05225, effectively protects against electric shock by reacting to even the smallest leakage currents. It is a two-pole switch with a rated current of 25A and a sensitivity of 30mA, designed to operate with alternating current (AC). Its construction based on proven technology guarantees reliable operation and long service life.

Construction and application

The IDK series RCD is an ideal solution for both residential and public buildings. Mounting is done on a DIN rail, which facilitates integration with the existing installation. Thanks to its compact dimensions (2 module width), it takes up little space in the switchboard. Double connection terminals (busbar + wire) and the ribbed surface of the terminals ensure secure and durable connections of wires with a cross-section from 1 to 35 mm² (solid) or from 1 to 25 mm² (stranded). The neutral conductor located on the left side facilitates alignment with overcurrent switches, and the presence of a "T" test button allows for regular verification of the device's functionality – recommended once a year for the first 7 years of use.

Key features and benefits

• Protection against electric shock: The switch instantly disconnects the circuit when a leakage current is detected, minimizing the risk of electric shock to users.
• High reliability: Rated short-circuit capacity of 6kA provides effective protection against the effects of short circuits.
• Easy installation: DIN rail mounting and double connection terminals significantly speed up installation.
• Convenient operation: The "T" test button allows for simple verification of the correct operation of the switch.
• Versatility: Suitable for use in various types of electrical installations, both new and modernized.
• Safety: Rated impulse withstand voltage of 4kV provides additional protection against overvoltages.
• Durability: Made of high-quality materials, resistant to mechanical damage and environmental conditions (operating temperature from -5°C to 40°C).
• Compliance with standards: Meets safety standards, guaranteeing safe use.
