Sentrysocket provides a high level of protection against electrocution and is available in eight MK wiring device ranges to suit most applications.

Active Control Circuit
This version of Sentrysocket incorporates a ‘RE-SET’ mechanism and is mains failure sensitive ie. it will function under all normal conditions expected of an RCD but it will also trip in the event of a power cut or a dramatic reduction in mains voltage. This makes it ideal for use where hazardous situations could occur due to equipment such as rotating machinery and heat developing apparatus becoming suddenly energised  after a power cut.

Passive Control Circuit
This version of Sentrysocket incorporates a ‘STAY-SET’ mechanism and is mains failure proof, i.e. it will function under all normal conditions expected of an RCD but will not trip in the event of a power cut. This makes it suitable for freezers or use in inaccessible or unmanned locations.

ALL SENTRYSOCKETS ARE PULSATING D.C. AND A.C. FAULT CURRENT SENSITIVE PRODUCTS
