Residual current device P 304 4P 100 A 300 mA Type A DX3 series 411783

The DX³ series residual current device (RCD) is a critical component ensuring safety in electrical installations. It protects users from electric shock and safeguards against the consequences of earth faults, minimizing fire risk. The P 304 4P model, rated at 100 A nominal current and 300 mA residual current, with Type A characteristic, is ideal for both new installations and modernizations.

This four-pole device is compatible with the HX³ Optimal Power Distribution System, enabling wireless integration into electrical systems. This significantly speeds up and enhances the flexibility of installation and configuration. Additionally, compatibility with a wide range of accessories—auxiliary contacts, trip units, and drives—allows the device to be tailored to the specific requirements of individual installations.

The P 300 DX³ RCDs feature a built-in test button, enabling regular verification of proper operation—essential for ensuring continuous safety. The locking mechanism prevents accidental re-energizing after the device has tripped due to residual current detection. With a width of 4 modules, the device facilitates easy installation in space-constrained distribution boards.

• Versatile application: Ideal for protecting circuits with a nominal current of 100 A, suitable for both residential and commercial buildings.
• Shock protection: Effectively detects leakage currents and disconnects the circuit in case of hazard.
• Compatibility: Integrates seamlessly with the HX³ system, simplifying energy management and improving installation efficiency.
• Easy installation: Mounts on DIN rail TH35 and supports connection via comb busbars or pin terminals.
• Expandable functionality: Can be upgraded with DX³ series accessories such as auxiliary contacts and trip units.
• Durability: Withstands impulse current up to 0.25 kA and short-circuit current up to 10 kA, ensuring reliable operation under demanding conditions.

The device exhibits high resistance to environmental conditions, operating reliably in temperatures ranging from -25°C to 60°C. The IP20 protection rating ensures protection against finger contact and ingress of solid objects larger than 12.5 mm. Constructed from high-quality, mechanically and corrosion-resistant materials, it guarantees long-term, maintenance-free performance. The rated impulse voltage withstand (Uimp) of 4 kV confirms the high manufacturing quality of the device.
