Residual current circuit breaker iID-25-4-300-AC 25A 4-pole 300mA type AC A9Z14425

Safety and protection in your electrical installation

The iID-25-4-300-AC residual current circuit breaker is a key element ensuring the safety of people and protecting the electrical installation from the effects of short-circuit currents to earth. This four-pole device with a rated current of 25A and a sensitivity of 300mA of type AC effectively reacts to dangerous leakage currents, minimizing the risk of electric shock. It is a reliable protection for both residential, commercial and industrial installations.

Functionality and installation for professionals

This circuit breaker is characterized by a wide range of cross-sections of connected wires – from 1 to 25 mm² for multi-strand wires and from 1 to 35 mm² for solid wires. Installation is done on a standard DIN rail, and the device's width of 4 modules allows for efficient use of space in the distribution cabinet. Additionally, with a lock preventing accidental disconnection, it ensures continuity of power where it is crucial. The rated impulse voltage withstand of 6 kV guarantees resistance to overvoltages.

User comfort and advanced solutions

The device is equipped with an optical Visi-Trip indicator signaling the operation of the circuit breaker (short circuit or leakage), which facilitates quick identification of the fault location. The ability to remove a single device without having to remove the entire busbar significantly speeds up service and modernization work. The N conductor located on the left side facilitates busbarring with overcurrent circuit breakers. The circuit breaker also has a VisiSafe indicator informing about the state of the contacts. The short-circuit capacity of the device is 10 kA, which ensures effective protection even in the event of high short-circuit currents. Power losses are only 3.2 W, which translates into energy savings. The device operates at an ambient temperature of -5 to 60°C and has a protection degree of IP20.
