Key Types of RCDs

  • Type A RCDs:
    Detects both AC residual currents and pulsating DC residual currents. Type A RCDs are suitable for circuits with modern electronic loads, such as LED lighting, appliances with variable-speed drives, and EV chargers. They provide enhanced safety for systems with non-linear loads.
  • Type B RCDs:
    Designed to detect all forms of residual currents, including AC, pulsating DC, and pure DC currents. Type B RCDs are ideal for circuits in renewable energy systems, three-phase inverters, and EV chargers where pure DC currents may be present.
Pole Configurations
  • 2-Pole RCDs:
    These protect single-phase circuits by monitoring both the live and neutral conductors. They are commonly used in residential and small commercial installations for applications like lighting and socket circuits.
  • 4-Pole RCDs:
    These protect three-phase systems with or without a neutral connection. They are suitable for industrial and large commercial setups, such as motor controls, HVAC systems, and machinery.
Key Features
  • Earth Leakage Protection: Provides safety by disconnecting the circuit during earth leakage faults, preventing electric shocks and potential fires.
  • High Sensitivity: 30mA RCDs are standard for personal protection, ensuring compliance with safety standards.
  • Durable Construction: Built with robust materials to ensure reliability in demanding environments.
  • Standards Compliance: Fully compliant with IEC 61008 and BS EN 61008, ensuring safety and performance.
  • Wide Application Range: Available in multiple configurations to suit residential, commercial, and industrial needs.
Applications
  • Residential Systems:
    Safeguards circuits for lighting, power sockets, and appliances. Ideal for kitchens, bathrooms, and other areas with higher risks of electrical shock.
  • Commercial Buildings:
    Protects lighting, HVAC, and critical power circuits in offices, schools, and retail spaces.
  • Industrial Installations:
    Ensures the safety of high-load circuits, motors, and machinery in factories and warehouses.
  • Renewable Energy Systems:
    Essential for solar PV installations, battery storage, and EV charging systems, particularly when pure DC currents are involved (Type B RCDs).
Why Choose Live Electrical RCDs?
  • Enhanced Safety: Provides reliable protection against earth leakage faults for people and property.
  • Versatile Configurations: Offers Type A and Type B RCDs with 2-pole and 4-pole options to meet diverse requirements.
  • Future-Proof Design: Type B RCDs ensure compatibility with renewable energy systems and modern electronic equipment.
  • Standards-Compliant: Fully certified to international safety standards, ensuring reliable and durable performance.

Live Electrical RCDs are the perfect choice for safeguarding electrical systems across a wide range of applications. Whether for residential, commercial, or industrial use, these RCDs deliver reliable protection and compliance with modern safety requirements.
