Safety switch for leads, PRCD-S

Description

The PRCD‑S is a high‑performance safety switch for leads, engineered to provide reliable protection against electric shock in industrial and commercial environments. Designed as an inline device, it can be inserted directly into the power cable without the need for additional connectors or terminals.

Key Technical Features

• Voltage Rating: 230 VAC – suitable for standard European mains supply.
• Current Capacity: 16 A – capable of handling typical lighting and equipment loads.
• Switching Current: 0.03 A (30 mA) – meets the IEC 60364‑4‑41 standard for personal protection devices.
• Poles: 3‑pole switching – ensures simultaneous disconnection of all live conductors.
• Protection Class: IP55 – resistant to dust ingress and water jets, suitable for damp or outdoor installations.
• Approval Marks: VDE, SEV, GS from BG Cologne – confirming compliance with German safety regulations.

Design & Construction

The PRCD‑S features a robust plastic housing that protects the internal contacts and circuitry. The device is engineered to be compact and lightweight, facilitating easy integration into existing cable runs. Its design eliminates the need for external connectors, reducing installation time and potential points of failure.

Installation Guidelines

To install the PRCD‑S:

1. Cut the power cable to the desired length.
2. Insert the cable into the device’s terminal block, ensuring a secure mechanical and electrical connection.
3. Secure the device in place using the supplied mounting hardware or appropriate cable clamps.
4. Connect the other end of the cable to the load or distribution board.
5. Test the switch by applying power and verifying that it trips at 30 mA, restoring safety compliance.
