Residual current device P 302 2P 40 A 300 mA Type A TX3 series 411575

Protection and Safety in Your Electrical Installation

The residual current device P 302 2P 40A 300mA Type A from the TX³ series is a critical component ensuring the safety of people and equipment in electrical installations. This device effectively protects against electric shock and prevents fires caused by insulation damage or short circuits. Its operation is based on the immediate disconnection of the circuit upon detection of earth leakage current, minimizing the risk of hazardous situations.

Construction and Application

The device is designed for DIN rail mounting, simplifying installation and replacement. The rated residual current of 300 mA and Type A characteristic make it ideal for protecting circuits with devices generating pulsating currents, such as switch-mode power supplies or electronic controllers. The two-pole design (2P) enables protection of two phase conductors, and the rated voltage of 230V complies with the standard for most residential and commercial installations. With a width of 2 modules, the device ensures compactness and space savings in the distribution board.

Key Features and Benefits
