Residual current circuit breaker P304 4P 40A 30mA TYPE AC TX3 411708

Safety and reliability in your installation

The P304 residual current device (RCD) is a key element ensuring the protection of people and equipment in electrical installations. The device effectively protects against electric shock, acting as a supplementary protection in the event of insulation failure. Its construction, based on proven technology, guarantees reliable operation and long service life. DIN rail mounting simplifies integration with existing electrical infrastructure, and the ability to work with additional modules expands the functionality of the system.

Functionality and parameters

The four-pole switch with a rated current of 40A and a sensitivity of 30mA type AC is designed to operate in circuits with a voltage of 400V. The short-circuit capacity of 10kA ensures an effective response in the event of a short circuit. Made of high-quality materials, the switch is characterized by resistance to mechanical damage and weather conditions (operating temperature from -25°C to 60°C). The mechanical lock prevents accidental disconnection, increasing safety. The ability to connect wires with a cross-section from 0.75mm² to 35mm² (multi-stranded) and from 0.75mm² to 50mm² (solid) provides flexibility during installation. The width of the device – 4 modules – allows for optimal use of space in the switchboard.

Installation and operating comfort

The P304 switch from the TX³ series is distinguished by its simple installation thanks to the bottom clip and terminal covers. The possibility of equipping with auxiliary contacts, undervoltage and overvoltage releases, and remote drives allows you to adapt the device to the specific needs of the installation. The test button allows you to regularly check the correct operation of the switch, which is crucial for ensuring continuous protection. Made of halogen-free materials increases environmental safety. Compliance with EN 61008-1 confirms the high quality and safety of the product.
