SwitchFix - Switch Handle Lock / Circuit Breaker Locking Device
Electrical Isolation Procedures / Lockout Tagout (LOTO) Procedures often require that electrical switch handles be locked in the "off" position once equipment has been effectively isolated. A locking device is typically applied to the following isolating equipment:
- Switch handles
- Disconnect handles
- Circuit Breaker (CB) handles
Faulty or poorly designed isolation switch handles are potential killers.
Some isolator handles (eg Holec, Siemens) appear locked in the “off” position, however the handle can be easily rotated to the “on” position with the locking device in place. This occurs due to a previous de-isolation with the handle locking clip extended.
Some isolation switch handles (eg Terasaki) can be inadvertantly locked in the "on" position as only 35 degrees, or 25mm handle rotation, differentiates the "on" and "off" positions. Click here to view Newmont's Pajingo Gold Mine solution to this problem.
Replacing faulty switch handles with the same design is expensive and frustrating. The new isolator handle may be faulty again tomorrow.
SwitchFix Isolator Locks eliminate switch handle replacement costs, and provides positive switch locking! Users have commented that SwitchFix:
- Prolongs the life of existing switch handles.
- Provides simpler switch locking by reducing the need to use fiddly, lock scissors.
- Allows many more locks to be attached than what the original switch provided.
- Ensures a positive lock that just cannot be forced. It’s obvious that it’s safer!
- Is easy to fit. Just a screwdriver and spanner are needed.
- Offers a tough rust proof construction.
