## Description

QWORK Miniature Circuit Breaker (MCB) Lockout With Screw, Safe Isolation, 4 Pcs

Review: Only for DIN rail MCBs and Main Switches - They have the correct angle for DIN rail MCBs and Main Switches with a curved part to fit them. Note that the thread has a point to bite into the plastic of the switch. The ones pictured on the listing lack this and wouldn’t work so must have been pre-production samples or something. I have only tested these on MCBs and Main Switches sold in the UK and they work well to lock on or off. I can’t speak for MCBs and Main Switches sold in other countries.
Review: Great adaptable lockout device - These are very good, fit a variety of men's and main switches and much better then the fiddly small screw type. Thoroughly recommend
