Multi-Pole Breaker Lockout

The Brady BL03 is a red polycarbonate tie-bar lockout designed for multi-pole circuit breakers operating at 120/277V AC. It isolates and secures the breaker switch to support lockout/tagout procedures for electrical maintenance personnel. The device accepts a single padlock with a maximum shackle diameter of 9/32 in. Its compact body measures 1.87 in high, 2.25 in long and 2.6 in wide.

Replaces Ad-Hoc Lockout Methods

This lockout replaces improvised solutions such as tape, zip ties or generic clamps that do not isolate the switch or accept a padlock. The jump is worth it when a facility requires a dedicated, OSHA-compliant device that physically prevents the breaker from being re-energised during service. It is not for single-pole breakers or for panels where a tie-bar cannot span the switch toggles.

Capacity And Headroom

The polycarbonate body withstands temperatures from -20 Degrees F to 170 Degrees F, making it suitable for indoor and outdoor electrical panels in varied climates. It securely holds one padlock per lockout point, which covers standard single-authorised-worker procedures. It runs out when a procedure demands multiple padlocks on the same breaker or when the breaker geometry prevents the tie bar from engaging all poles simultaneously.

Questions about this item

What is the overall width of the BL03 lockout, and will it clear the adjacent breakers in a standard panel?

The lockout measures 2.6 in overall width, so confirm the spacing between your multi-pole breaker and its neighbours before fitting.

How do you install the BL03 tie-bar lockout, and what is the step installers most often miss?

Slide the red polycarbonate body over the breaker’s tie bar, insert a padlock with a shackle no larger than 9/32 in through the hole, and verify the switch cannot be moved — the missed step is testing the toggle after locking.

At what temperature should the BL03 polycarbonate body be inspected or replaced?

The material is rated from -20 °F to 170 °F; if the lockout sees temperatures outside this range or shows cracking, discolouration or deformation, replace it.
