Miniature Circuit Breaker (MCB) Lockout System
A fuse, as we all know, needs to be replaced once operated. These days, most of the circuits come with an alternative and that is a Miniature Circuit Breaker (MCB). An MCB Lockout is an electromagnetically device which operates as an automatic switch and protects an electrical circuit from damage caused by excess current or overheating, generally caused by a short-circuit or a faulty design. Unlike a fuse, when an overload is detected, an MCB doesn’t have to be replaced. It can be reset, either manually or automatically and continue to function and thus offers an improved functioning and operational safety without additional costs. In a nutshell, an MCB functions as a switch that automatically turns off when the flowing current passes the allowed limit.
A miniature circuit breaker comprises of two contacts, fixed and moveable. A solenoid forces the moveable contact to disconnect from the fixed one whenever the current exceeds the allowed limit, thereby stopping the current flow through the circuit. This mechanism protects from current over load. However, a bi-metallic strip is used to protect from overheating and increase in temperature. The overload causes the temperature to rise and subsequently, the bi-metallic strip heats and deflects. The deflection then releases the trip latch and separates the contacts.
Miniature circuit breakers serve two purposes. They function as a fuse and as a switch. By toggling the switch to the ‘off’ position, the circuit can be opened for safety and maintenance purposes. Before the maintenance process begins, miniature circuit breakers need to be locked and tagged out. This ensures that they are not accidentally reactivated while maintenance is still in process.
While there are numerous companies dealing in lock out devices, Lockout India manufactures safe, effective and reliable universal miniature circuit breakers lockout devices that work on most circuit breakers throughout the world. They comply with OSHA’s safety standard 1910.147 and ensure that electrical energy sources are locked out for optimum work safety. These lockout devices are manufactured using durable plastics and effectively lock out the circuit breakers. These can be used for single, double, triple and quadruple pole MCB and can be easily installed using a screwdriver.
