Residual current circuit breaker P304 4P 25A 30mA TYPE AC TX3 411707

Safety and protection in your electrical installation

Residual Current Device (RCD) P304 4P 25A 30mA type AC from the TX³ series is a key element ensuring the safety of using the electrical installation. Its task is to quickly disconnect the circuit in the event of a leakage current, protecting users from electric shock and preventing fires. This is a reliable protection for both installers and end users.

Functionality and application

This device, with a rated current of 25A and a differential current of 30mA, is designed for use in circuits with a rated voltage of 400V and a frequency of 50Hz. The four-pole design makes it ideal for protecting polyphase electrical installations. The circuit breaker is characterized by a high breaking capacity of 10kA, which guarantees its effective operation even in the event of serious disturbances. Mounting is on a DIN rail, which simplifies and speeds up installation.

Construction and characteristic features

The P304 TX³ circuit breaker is distinguished by a solid construction and high quality of workmanship. It has a mechanical lock, preventing accidental switching on of the circuit breaker after it has been switched off by the operation of the residual current device. The ability to cooperate with additional auxiliary devices (auxiliary contacts, signaling devices) expands the functionality of the device and allows it to be adapted to the individual needs of the installation. The use of a lower bracket and terminal cover facilitates the installation and connection of wires with a cross-section from 0.75 mm² to 35 mm² (stranded) or from 0.75 mm² to 50 mm² (solid). The degree of protection IP20 provides protection against finger contact.

• Type AC: Detects sinusoidal alternating differential currents – standard protection for most domestic and industrial applications.
• High breaking capacity: 10 kA guarantees reliable operation in difficult operating conditions.
• Expandability: Compatibility with DX³ series auxiliary devices allows the circuit breaker to be adapted to specific installation requirements.
• Modular width: Occupies 4 modules on a DIN rail, allowing for optimal use of space in the distribution board.
• Operating temperature: Trouble-free operation in the temperature range from -25°C to +60°C ensures reliability even in extreme environmental conditions.
• Compliance with standards: Meets the requirements of EN 61008-1 standard, which confirms its safety and quality.
