Residual current device P 304 4P 80 A 500 mA Type A DX3 series 411792

Safety and Protection in Your Electrical Installation

The residual current device P 304 4P 80A 500mA Type A from the DX3 series is a critical component ensuring safe operation of electrical installations and protection against electric shock and fire hazards. The device effectively detects leakage currents and disconnects the circuit in case of a fault. This is especially important in high-risk areas such as bathrooms and kitchens, but also in any circuit powering electrical equipment.

Functionality and Application

Designed for DIN-rail mounting, this device performs excellently in both new installations and modernization of existing systems. The rated current of 80A enables protection of circuits with higher power demand, while Type A sensitivity ensures detection of both alternating sinusoidal currents and pulsating direct currents—enhancing the scope of protection. The four-pole design allows full circuit protection. Thanks to compatibility with the HX³ Optimal Energy Distribution System up to 125A, integration with modern energy management systems is simple and efficient.

Construction and Key Features

The P 304 DX³ breaker features a robust construction and high manufacturing quality. It includes a test button enabling regular verification of its functionality—essential for ensuring continuous safety. The mechanical latch prevents accidental re-energizing of a faulty circuit. With a width of 4 modules, installation in space-constrained electrical panels is straightforward. Additionally, compatibility with DX³ series accessories (auxiliary contacts, trip units) allows customization of functionality to meet specific installation requirements. The rated short-circuit capacity of 10 kA ensures effective protection even during high surge events. The enclosure is rated IP20 and provides basic protection against contact and dust ingress.
