RCD Sockets - The Difference Between Latching and Non-Latching

Latching RCD (Sometimes called Passive)

When the power is lost due to an earth fault, the RCD trips out and isolates the circuit it is protecting. Latching RCDs do trip during power cuts but they automatically reset once the power returns, so they are great for fridges and freezers and also for protecting remote/unmanned areas. This would also make them ideal for protecting some heating equipment set to "Frost Protection", fish tanks and battery charging.

Use Latching (Passive) RCD Sockets For:

Refrigeration

Frost watchers

Aquariums

Chargers

Remote installations

Most commercial applications

Non-Latching RCD Sockets (Sometimes called Active)

When the power is lost due to earth fault or power cut, the RCD isolates the circuit that it is protecting and remains off until it is manually reset. A must for protecting circuits supplying rotating machinery or some heating apparatus for example.

Use Non-Latching RCD Sockets For:

Garden tools

Power tool

Domestic applications

Nurseries

Schools

Hospitals

Old peoples homes
