MK Sentry RCBO 50A H7939S Type B, single pole, single module format. H7939S provides an overcurrent rating of 50A, a trip current of 30mA and a breaking capacity of 6kA. For usage with all MK Sentry Consumer Units and MK Sentry Enclosures.

A one module MK Sentry RCBO combines the capabilities of a Type B MCB and an RCD, providing residual current and earth leakage protection alongside overcurrent protection, all within one unit. Combining Earth fault Protection and overcurrent protection within one module allows for interruption of only the faulty electrical circuit, rather than interrupting all circuits within the electrical system, providing improved safety and reducing unnecessary inconvenience.

The dolly switch can be locked into the ON or Off position without affecting the ability of the trip mechanism to operate. MK Sentry RCBOs provides large tunnel terminals at 25mm² for live and neutral terminals. In accordance with the 17th Edition IEE Wiring Regulations MK Sentry RCBO's feature positive contact status indication
