Siemens HL9419 Qj Circuit Breaker Padlock

Product Description

The SIEMENS HL9419 is a padlock accessory designed for use with QJ series circuit breakers. It provides a mechanical locking mechanism that prevents unauthorized or accidental operation of the breaker handle. This type of lockout accessory is a standard safety component in commercial and industrial electrical panels. It is installed by licensed electricians during lockout/tagout procedures or wherever code or site safety policy requires a secured breaker position.

This padlock accessory is suited for applications where breaker handle security is required, including commercial electrical distribution panels, industrial control systems, and facilities subject to OSHA lockout/tagout regulations. It is used in both new installations and retrofit scenarios where existing QJ series breakers need to be secured against unauthorized re-energization.

Installation Notes

Installation should be performed by a licensed electrician. Before installing or removing any breaker accessory, de-energize the panel and follow all applicable NFPA 70 (NEC) and OSHA lockout/tagout requirements. Do not force the padlock accessory onto the breaker handle, as improper fitment can interfere with proper breaker operation. Verify compatibility with the specific QJ series breaker model prior to installation.
