Master Lock 493B Grip Tight™ Circuit Breaker Lockout for Electrical Lockout on Standard Single and Double Toggles, 13 x 7 x 3 cm

Required to lock off mob isolator. Better designed mcb with locking capability would be better

Good price to add to my kit

Needed for MCCB’s

Whilst this seems to be able to get a very sturdy grip onto the switch of an MCB, due to the curve of the MCB this does not sit flush and as such gives enough leverage that it can be pulled off the MCB switch. I haven't marked it down as I don't feel this is designed for MCB's but for circuit breakers with flat switch surfaces. Just be aware when buying, NOT FOR CURVE FACED MCB's

Easy to use and good quality

Me parece de buena calidad y robusto. un poco caro pero contento con la compra

Works extremely well . Was impressed . Would buy it again .

Cet accessoire de condamnation de disjoncteur est presque universel pour réaliser une consignation (avec le cadenas qui va bien), si le disjoncteur présent une manette de commande accessible

I bought this breaker lock-out as a reminder to not turn this breaker on, unless you really need it. I use this on the 240V, 50 AMP, Electric Vehicle / Recreational Vehicle outlet that I installed under our breaker panel. Most of the time, this should be turned OFF, but on rare occassion it needs to be turned on. This Lock-out makes it really easy to remember to keep it turned Off when not needed and prevents people from turning it on by accident. The quality of construction is excellent and although I didn't need to use the fitment accessories that came with it, I appreciate that they were included. Nothing is as frustrating as not being able to finish a project beause of a fitment issue. Master Lock had this in mind and they have you covered. Great little product. I would definately buy it again.

Ya lo puse, esperemos y haga su función, intente bajar el switch y no se pudo.
