Sentry MCB ( Type B )

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.
