A clear installer guide to 100mA S-Type RCDs. Learn when time-delay protection is needed, why they''re used on TT systems, and
In OC relays the coordination is based on the relay time-current characteristics of instantaneous and/or time delay units.
Selectivity between RCDs is achieved either by time-delay or by subdivision of circuits, which are then protected
A time delay (S-type) RCD is deliberately slow to trip — allowing a downstream 30mA RCD to operate first. This maintains selectivity
