Residual current circuit breaker EFI-P2 A 40/0.1 002061122

Safety and Reliability in Your Electrical Installation

The Residual Current Device (RCD) EFI-P2 A 40/0.1 is a key element in protecting your electrical installation, protecting against electric shock and potential fire hazards resulting from insulation damage. The device is designed for use in TN-S, TN-C-S, TT and IT networks where the neutral and earth conductors are separated. Its operation is based on the rapid detection of current differences in the circuit, allowing for immediate disconnection of the power supply in the event of a fault.

This two-pole switch with a rated current of 40A and sensitivity A (reacts to alternating and pulsating currents) provides effective protection for both end users and installed devices. Thanks to its compact dimensions (width 2 modules, depth 68 mm) it is easy to mount on a DIN rail in a distribution box. The IP20 degree of protection guarantees safe use in standard environmental conditions.

Construction and Application

The RCD EFI-P2 A 40/0.1 is characterized by a solid construction and high quality workmanship, confirmed by a fully automated production line. It has a "Test" button, allowing you to regularly check its functionality. Additionally, the contact position indicator makes it easy to identify the switch status (ON/OFF). The connection terminals are adapted for conductors with a cross-section of 1-25 mm², both solid and stranded, providing flexibility during installation.

The device finds application in a wide range of electrical installations – from domestic to industrial. It is particularly important wherever there is a risk of electric shock or damage to cable insulation. In accordance with DIN VDE 0100-482 and IEC 60364-4-482 standards, residual current devices with a differential current of up to 300 mA are essential to ensure fire protection in TN and TT systems.

Key Features and Parameters

• A rated current of 40A provides protection for circuits with appropriate load.
• High sensitivity to leakage currents thanks to a differential current of 0.1 A (100 mA), guaranteeing a quick response in the event of a fault.
• Type A provides protection against alternating and pulsating DC currents – versatility of application in various types of installations.
• Short-circuit strength at the level of 10 kA ensures resistance to the effects of short circuits in the electrical network.
• Rated voltage of 240 V guarantees compatibility with most power grids.
• DIN rail mounting allows for easy and quick mounting in standard distribution boxes.
• IP20 degree of protection provides protection against finger contact and solid objects larger than 12.5 mm
• Possibility of connecting conductors with a large cross-section thanks to the cross-section of the connecting conductor of 25 mm².

The EFI-P2 A 40/0.1 switch is an investment in the safety and reliability of your electrical installation, meeting the highest standards of quality and compliance with applicable standards.
