Residual current device P 304 4P 63 A 500 mA Type A, TX3 series 411796

Safety and Reliability in Your Electrical Installation

Residual current circuit breaker (RCCB) series TX³ is a key component ensuring protection of people and equipment in electrical installations. It provides effective protection against electric shock and fire hazards by detecting leakage currents. Its design, based on proven technology, guarantees reliable operation under various conditions.

This four-pole (4P) RCCB with a rated current of 63A and sensitivity A (500mA) is ideal for protecting circuits requiring high-efficiency protection against leakage currents, including those generated by electronic devices. Type A indicates that the device responds to both alternating and pulsating leakage currents — a crucial feature in modern installations.

Installation and Functionality for Professionals

Mounting the RCCB on a DIN rail is fast and intuitive thanks to the bottom clip and insulated terminal covers. This enables easy connection of conductors with cross-sections from 0.75 mm² to 50 mm² (single-core) or 35 mm² (multi-core). An additional lock prevents accidental opening of terminals, enhancing safety during work. The RCCB also features a test button, allowing regular verification of its proper operation — a requirement under many regulations and standards.

Compatibility with auxiliary devices (auxiliary contacts, signaling contacts, trip units) extends the functionality of the RCCB and allows customization to specific installation needs. Withstand capability for impulse current up to 0.25 kA and rated short-circuit capacity of 10 kA (compliant with IEC/EN 61008-1) ensure reliable operation even during overloads or short circuits.

Robust Construction and Compliance with Standards

The RCCB is constructed from high-quality materials, ensuring durability and resistance to mechanical damage. It complies with VDE 0664-10 and EN 61008-1 standards, confirming its safety and conformity with applicable regulations. The housing in RAL 7035 color provides an aesthetic appearance and integrates well with other electrical installation components. Protection rating IP20 guards against accidental contact and ingress of solid objects larger than 12.5 mm. Operation in ambient temperatures from -25°C to 60°C enables use across a wide range of environmental conditions.
