Residual current device P 304 4P 80 A 100 mA Type A DX3 series 411772

The differential current switch P 304 4P 80 A 100 mA Type A, DX3 series, is a critical component ensuring safety in electrical installations. The device protects users from electric shock and provides protection against the effects of short circuits and overloads. This four-pole switch is designed for operation in networks with a voltage of 400 V and a frequency of 50 Hz, with a rated current of 80 A and a differential current sensitivity of 100 mA.

The switch’s construction is based on the proven Legrand DX³ technology, guaranteeing reliability and long service life. It is mounted on a DIN rail, with a width of 4 modules, facilitating seamless integration into existing distribution boards. The switch features a lock that prevents accidental re-energizing after a fault-induced trip. The rated impulse voltage withstand is 4 kV, and the breaking capacity reaches 10 kA, ensuring effective protection against sudden voltage surges or short circuits.

The P 304 DX³ switch is compatible with the HX³ Optimal Energy Distribution system, enabling wireless connection to the electrical installation. The option to add auxiliary and signaling contacts allows for functional expansion and customization to meet specific installation requirements. Designed to operate in a wide temperature range—from -25°C to 60°C—it remains reliable even under harsh environmental conditions. The connected conductor cross-sections range from 0.75 mm² to 50 mm² for single-core cables and from 0.75 mm² to 35 mm² for multi-core cables, offering great flexibility during installation.
