SAMRC series 16A 230V socket incorporating MCB, RCD and Monitored Earth protection to provide supplies to NHS mobile trailers. Assembly incorporates a supplementary earth connection via a POAG-ID6 socket. Other ratings available to order.

RCCB, MCB and Monitored Earth protected socket housed in a surface mounting, all-insulated enclosure. The assembly incorporates a standard 16A 3 pin socket and a POAG-ID6 connector, both of which normally supply a mobile trailer. To operate, a 3P plug needs to be inserted into the 16A socket and a POAG plug needs to be inserted into the POAG socket, which completes the pilot-earth loop to and from the appliance / trailer. The contactor within the assembly will open: (i) if the earth connection via the 3P socket is broken; (ii) if the return connection via the POAG-ID6 connector is removed; or (iii) if the impedance of the pilot-earth loop rises above 1.5 ohms.

For “User Friendly” operation, the Earth Continuity Monitoring device controls an integrally mounted contactor with external ON / OFF push switches, which provides an easy means of turning the supply to the socket ON and OFF. Please note that the unit meets an ingress protection rating of IP44 except for the POAG-ID6 connector, which has no IP rating.

25A DP 30 mA sensitivity to BS EN 61008, Type A.

16A SP Type “C” to BS EN 60898.

Pilot-Earth loop trip factor of 1.5 ohms, providing protection in accordance with BS4444.

Fitted with a 16A 3P 230V IP44 socket to BS EN 60309-2.
