Residual current circuit breaker iID-25-2-30-AC 25A 2-pole 30mA type AC A9Z11225

Residual Current Device (RCD) iID-25-2-30-AC is a key element ensuring the protection of people and electrical installations against the effects of leakage currents. The device, with a rated current of 25A and a sensitivity of 30mA, is designed to operate in alternating current (AC) circuits and effectively reacts to sinusoidal leakage currents, minimizing the risk of electric shock. Its two-pole design makes it ideal for securing circuits in homes, apartments, commercial buildings and industrial facilities.

Comfort of installation and use

The iID series circuit breaker is distinguished by a well-thought-out design that facilitates both installation and subsequent operation. Mounting on a DIN rail is quick and intuitive. Double terminals allow you to connect two wires of different cross-sections – this saves time and flexibility during installation. The Visi-Trip optical indicator informs about the tripping of the device, which facilitates troubleshooting. Additionally, the ability to remove a single circuit breaker without having to disassemble the entire busbar significantly speeds up service work.

Design features and parameters

The device is characterized by high reliability confirmed by the withstand to short-circuit current at the level of 10kA. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 6kV – this ensures safe operation even in difficult conditions. The width of the circuit breaker, 2 modules (36mm), allows for optimal use of space in the switchgear. The power loss of the device is 3.2W at a frequency of 50/60Hz. The cross-section of the connectable solid wires is 1…35 mm², and stranded wires 1…25 mm². The ambient temperature in operating conditions is in the range of -5 to 60°C, which guarantees stable operation in various environments. The rated differential current is 0.03A (30mA).
