Residual Current Device (RCD) iID-25-4-300-A 25A 4-pole 300mA type A A9Z24425

Residual Current Device (RCD) iID-25-4-300-A is a reliable protection for electrical installations, protecting against the effects of leakage currents. It is a four-pole device, designed to protect people and property in AC installations with a voltage of up to 400V. Its use in homes, commercial and industrial buildings guarantees safe operation.

Characteristics and application

This type A residual current circuit breaker, with a rated current of 25A and a sensitivity of 300mA, effectively detects earth leakage currents, disconnecting the circuit in case of a hazard. This minimizes the risk of electric shock and equipment damage. The device's construction allows for mounting on a DIN rail, which facilitates installation and integration with existing electrical systems. The ability to connect wires with a cross-section from 1 to 25 mm² (multi-stranded) or 1 to 35 mm² (solid core) provides flexibility in wire selection.

Construction and user features

The circuit breaker is characterized by a solid construction and high quality workmanship. It has a mechanical lock, preventing accidental switching on after tripping by the residual current protection. An optical trip indication (Visi-Trip) makes it easier to identify the cause of the circuit disconnection. The device is designed to operate in a wide range of ambient temperatures (-25°C to +60°C) and has an IP20 degree of protection, which ensures resistance to dust and touch. Additionally, the ability to remove a single device without removing the busbar and removal from the DIN rail without tools significantly facilitate service and maintenance work. The withstand to impulse current is 0.25 kA and the short-circuit withstand capacity (Icw) is 10 kA. Power losses are 3.2W at a rated voltage of 400V and a frequency of 50/60Hz.
