Single-Pole Breaker Lockout

The Brady 148690 is a clamp-on lockout device designed for single-pole circuit breakers rated up to 120/277V AC. It accepts one padlock with a maximum shackle diameter of 9/32 in and includes features for pre-loaded ID tags on TagLock devices. The unit requires no separate lock to operate.

Clamp-On Fit and Clearance

The lockout mounts directly onto the breaker toggle with an overall width of 1.06 in, height of 1.38 in and length of 2.63 in. It suits breakers with a maximum switch width of 2.63 in and works with standard nylon cable ties for added security. This compact profile leaves adjacent breakers accessible in crowded panels.

Upgrade from Improvised Lockouts

Replaces makeshift solutions such as tape, zip ties alone or generic clamps that lack a dedicated padlock point and tag integration. The jump is worth it when a facility requires a repeatable, OSHA-aligned lockout point for single-pole breakers and needs pre-loaded identification for audit trails.
