MKElectric Sentry 6A Single Pole Type B MCB

Description

Sentry 6A single pole 230V one module miniature circuit breaker is of the thermo-magnetic, current limiting type and are available with Type B operating characteristics. It has been carefully designed and engineered using thermal and magnetic elements to detect overcurrents due to both overload and fault currents. It will operate and interrupt the supply to prevent damage to the installation. The thermal component is a carefully calibrated, thermally operated bi-metal element. The operating dolly may be locked in either the On or Off position without affecting the ability of the trip mechanism to operate. The contacts themselves are manufactured from carefully chosen materials, selected specifically for their low electrical resistance and low propensity to weld under fault conditions. When the green indicator is visible, then a contact gap of 4 mm has been achieved. It may be used as single pole isolating switches where appropriate. Features tunnel terminals of 35mm² capacity on all ratings. Each terminal has a protective shutter to prevent cable being installed incorrectly. The terminal screws are touch proof to IP2X, captive and feature combination heads. Type B has magnetic operating limits are between 3 and 5 times the current rating of the MCB. Under these conditions the mechanism of a 10A MCB will operate between 30A and 50A in an overcurrent situation.
