Sentry MCB ( Type C )

20 Amp MCB C Type - Motor Rated

Type C devices are capable of supplying the majority of inductive and capacitive loads such as motors, transformers and tungsten or fluorescent lighting.Surges on energisation, for example with discharge lighting, may well reach 25 times the rated current of the device, but only for very short duration. Type B devices will often be adequate, but for more specialised circuits, a Type C may be required. The lighting fitting manufacturer’s recommendations should be observed.
Sentry MCB detect overcurrents due to both overload and fault currents.
The MCB will operate and interrupt the supply to prevent damage to the installation.

  • All Sentry MCBs have a short circuit breaking capacity of 6000A (M6).
  • The current carrying capacity of the cable should always exceed the current rating of the MCB to prevent damage.
  • The operating dolly may be locked in either the ON or OFF position without affecting the ability of the trip mechanism to operate.
  • When the green portion of the dolly is visible, then a contact gap of 4 mm has been achieved. Sentry MCBs may therefore be used as single pole isolating switches where appropriate.
