Protect your employees' lives during maintenance by isolating energy sources in your plant. This circuit breaker lockout device securely fastens to electrical installation panels, adapted for ATEX sites. It locks out most miniature ISO/DIN circuit breakers worldwide, featuring a thumb turn dial screw for easy, tool-free attachment. The dimensions are 6.4 x 5.7 x 3.2 cm, and it can be mounted side-by-side on adjacent miniature circuit breakers. The device accepts all American Lock and Master Lock safety padlock shackles and lockout hasp diameters. Master Lock offers a limited lifetime warranty and a comprehensive range of lockout/tagout solutions designed to help facilities meet or surpass local standards and LOTO requirements. The patented device attaches to the circuit breaker, making the dial inaccessible in the locked position to prevent removal. Padlocks can be applied horizontally or vertically. The device works with all American Lock and Master Lock safety padlocks and lockout hasps (does not include ALO80 or ALO802).
