Product FAQs
6 answersWhat does the HID designation mean on the THQL1120HID breaker?
The HID suffix indicates the breaker is High Intensity Discharge rated. It is engineered to handle the high inrush currents generated when switching HID and fluorescent lighting systems on and off, preventing nuisance tripping.
Can I install the THQL1120HID in an older GE load center?
Yes, this Q-Line breaker is backwards compatible with legacy GE PowerMark Gold Load Centers and GE A-Series Panelboards, as well as current ABB ReliaHome Load Centers.
What are the conductor requirements for wiring the THQL1120HID?
The screw clamp box lugs are rated for both copper and aluminum conductors. Use 14 to 8 AWG for copper wire, or 12 to 8 AWG for aluminum wire.
Why might my THQL1120HID breaker arrive with ABB branding instead of GE?
Following ABB's acquisition of GE Industrial Solutions, Q-Line breakers may feature either ABB or GE branding depending on the production batch. The breakers are identical in form, fit, and function.
Does the THQL1120HID require bolt-on hardware for installation?
No, this is a THQL frame breaker which features a plug-on mounting design. It snaps directly onto the bus bars of compatible load centers without the need for mounting screws or DIN rails.
Does the THQL1120HID provide adjustable trip settings for coordination?
No, it is equipped with a fixed thermal-magnetic trip unit. The long-time and instantaneous (LI) trip functions are factory set and non-interchangeable.
