HRD7 RCBO — 1P+N / 3P+N, 6–32A (Magnetic / Electronic)
3 phase rcbo HRD7 with 1P+N / 3P+N options for single- & three-phase distribution, In 6–32A.
Type AC / Type A, IΔn 10 / 30 / 100 / 300 mA; Icn 6 kA, Ue 240 / 415 V, 50/60 Hz.
Magnetic / Electronic versions; endurance Mechanical 12,000 / Electrical 6,000 cycles; IEC/EN 61009-1, SEMKO / UKCA / CE / SAA.
3 phase rcbo HRD7 integrates residual-current and overcurrent protection in compact 1P+N and 3P+N formats, covering 6–32 A at 240/415 V, 50/60 Hz. It is available in both magnetic and electronic versions to match different coordination strategies and installation preferences.
개요
HRD7 is designed for residential, commercial, and light-industrial boards where
combined RCD + MCB functionality is required on single-phase and three-phase circuits.
With Type AC / Type A residual protection and four standard sensitivities
(10 / 30 / 100 / 300 mA), HRD7 achieves reliable touch protection and discrimination.
The range supports 1P+N and 3P+N configurations with a 6 kA breaking capacity
to address common fault levels on 240 V / 415 V grids. This three phase rcbo option
supports coordinated selectivity on three-phase boards.

표준 및 규정 준수
Conforms to IEC/EN 61009-1. Certified by SEMKO, UKCA, CE, SAA.
Always verify discrimination and coordination with upstream devices and local codes.
자주 묻는 질문
When should I choose HRD7 magnetic vs electronic?
Magnetic versions suit simpler coordination and rugged operation; electronic versions may offer finer residual detection behavior and stable performance across wider conditions. Select based on coordination studies and installation specs.
What IΔn should be used upstream vs downstream?
Downstream final circuits commonly use 30 mA. Upstream feeders often adopt 100–300 mA to maintain selectivity. Follow local codes and discrimination rules.
Does HRD7 support both single-phase and three-phase boards?
Yes. Use 1P+N for single-phase branches and 3P+N for three-phase circuits that require neutral protection.
