The NHP MOD6+ RCBO (MD6RS 30A) is a high-quality residual current breaker with overcurrent protection, designed for domestic, commercial, and light industrial installations. Featuring a 6kA short-circuit rating, 30mA earth leakage protection, and a neutral tail (pigtail) for easy installation, this compact device provides both overload and earth leakage protection in a single 18mm DIN-mounted module.

Key Features:

  • Combined RCD and MCB Protection: Protects against short circuits, overloads, and earth leakage faults, providing complete circuit protection.
  • 6kA Breaking Capacity: Suitable for installations requiring a 6,000A short-circuit withstand, meeting Australian standards.
  • Type A Leakage Protection: Detects both AC and pulsating DC residual currents for enhanced safety across a wider range of electrical loads.
  • C Curve Trip Characteristic: Ideal for general-purpose applications, handling inrush currents typically found in lighting, small motors, and general appliances.
  • Switched Neutral with Pigtail Tail: Includes a pre-wired 1-pole + switched neutral configuration with neutral tail, simplifying wiring and reducing installation time.
  • Compact 18mm Width: Saves valuable space in crowded switchboards, ideal for modern distribution boards.
  • Extended Mechanical and Electrical Life:
    • Mechanical life: 20,000 cycles
    • Electrical life: 10,000 cycles
  • DIN Rail Mounted: Quick and secure mounting into standard DIN rail switchboards.

Q: What type of residual currents does the Type A RCBO detect?
A: It detects both pure AC and pulsating DC faults, offering broader protection for modern electrical appliances.

Q: Is this RCBO suitable for use in homes and commercial buildings?
A: Yes, it's fully compliant for residential and commercial use under AS/NZS standards.

Q: Does this RCBO switch the neutral conductor?
A: Yes, it switches both active and neutral poles (switched neutral) for improved fault isolation.

Q: What installation method is required?
A: It is designed for standard DIN rail mounting and must be installed by a licensed electrician.

All products must be installed by a licensed electrican. DIY electrical work is illegal and very dangerous.
