Where this product is used

Master Lock circuit breaker lockout products are used in industrial maintenance, construction, electrical, and process environments where energy isolation, lockout/tagout compliance, and general security are required.

• MCB and MCCB lockout devices for positive isolation of circuit breakers in electrical distribution boards during electrical maintenance.

Key specifications

Refer to the product title and model number for size, capacity, and configuration details.

Selecting the right option

Confirm the circuit breaker type (MCB, MCCB, Griptight, or toggle) and breaker width before selecting a lockout device — the Griptight series suits variable breaker widths; clip-on devices are breaker-width specific.
