Locking Device for Siemens Breakers

This locking device fits Siemens QP, BL, BQ and BQXD single-pole circuit breakers. It provides a mechanical lock-off point on the breaker toggle to support lockout/tagout procedures. The unit is supplied new and ready for immediate installation on compatible panels.

Simple Field Installation

The device clips onto the breaker toggle without tools, using the 2.7 in length and .8 in width footprint. No wiring changes are required. The only common issue is selecting the wrong pole version; this model is for single-pole breakers only and will not fit two- or three-pole devices.

Suited for Maintenance and Safety Teams

Electricians and facility managers who need to isolate individual single-pole circuits will find this device effective. It is not intended for multi-pole breakers or for applications requiring a padlock hasp integrated into the breaker body itself.

Questions about this item

How do I confirm the ECQLD3 locking device is properly engaged on my QP breaker?

After installation, the mechanical latch should sit flush against the breaker body and prevent the toggle from moving to the ON position when locked.

What comes in the box with the ECQLD3 and what must I source separately?

The package contains only the locking device itself; you must supply the compatible Siemens QP, BL, BQ or BQXD 1-pole breaker and any mounting hardware.

Which version of the ECQLD3 fits my specific Siemens breaker series?

This single device fits all listed series — QP, BL, BQ and BQXD — provided the breaker is a 1-pole model.
