RCD Selection Guide: Key Principles for Safe and Compliant Design

In modern electrical installations, Residual Current Devices (RCDs) are critical for protecting against electric shock and fire hazards. We offer a comprehensive range of RCDs with varying sensitivities (10mA, 30mA, 100mA, 300mA), ensuring compliance with the latest safety standards.

Key RCD Types & Their Applications

Why Choose MK Circuit Protection RCDs?

1. Premium Contact Technology

• Silver-plated T2 copper reduces contact resistance and improves heat dissipation, lowering temperature rise under load for enhanced current rating and long-term reliability.

2. Superior Arc Protection

• Silver-tungsten (moving contact) + silver-graphite (fixed contact) delivers high resistance to welding & erosion, even under inductive/capacitive loads – ensuring 10kA breaking capacity and 10,000+ electrical operations.

3. Foolproof Modular Construction

• Pre-assembled CT & trip unit eliminates installation errors, preventing PCB or component damage for consistent, reliable performance.

4. Full Compliance & Safety

• Meets BS EN 61008 and BS 7671 requirements, guaranteeing industry-standard protection for residential, commercial, and industrial applications.

Whether you’re designing a residential system or an industrial installation, selecting the right RCD type ensures safety and reliability.
