The SIEMENS H37892 is a Talon lug accessory designed for use with HQ-series circuit breakers. It features a 9/16 inch stud and a 3/8 inch Allen drive, accepting conductors ranging from No. 4 through 500 MCM. This lug provides a secure termination point for large-gauge conductors in panel and breaker installations. Electricians use this accessory to extend or adapt the termination capacity of compatible HQ breakers, ensuring a code-compliant mechanical connection at the breaker terminal. The MCM range makes it suitable for high-ampacity branch and feeder circuit work.

This lug accessory is intended for use in commercial and residential electrical panel installations where HQ-series breakers are deployed. It is most commonly installed during service upgrades, panel builds, or conductor termination work requiring a reliable mechanical lug rated for large wire gauges up to 500 MCM. Licensed electricians performing load-side termination work on HQ breakers are the primary installers.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the panel and verify absence of voltage before installing or removing any lug accessory. Use a calibrated torque wrench with the correct 3/8 inch Allen bit to achieve proper termination without over-torquing the stud. Ensure conductor insulation is stripped to the correct length and that no stray strands are present at the terminal.
