Abb thql1130pgft 30A 1-pole Circuit Breaker Plug-on Neutral

Product Description

The ABB thql1130pgft is a Type THQL, single-pole, plug-in molded case circuit breaker rated for 30 amps at 120/240 volts AC. Part of the ABB Q-Line Plug-In series, it incorporates a 5 mA ground fault circuit interrupter (GFCI) with a self-test feature, providing both overcurrent and ground fault protection in a single device. The interrupt rating is 10 kAIC. Box-type terminals accept wire sizes from 14 to 8 AWG copper or 12 to 8 AWG aluminum. Quick-make, quick-break operation and a plug-on neutral connection make this breaker well-suited for residential load center installations. It is UL Listed under Molded Case Circuit Breakers No. 489 and qualifies under Federal Government Specification WC-375B.

This breaker is designed for use in residential electrical panels that support the plug-on neutral configuration, eliminating the need for a separate neutral pigtail. The GFCI function with self-test capability satisfies NEC requirements for ground fault protection in bathrooms, kitchens, garages, outdoor circuits, and other locations where GFCI protection is mandated. The single-pole, 30-amp rating covers branch circuits such as electric dryers or dedicated appliance circuits that fall within the wire-size and ampacity range of this device. Installation is performed by licensed electricians working within applicable NEC guidelines.

Key Features

Compatibility

Designed for use in residential load centers that accept the ABB Q-Line Plug-In (Type THQL) breaker series with plug-on neutral bus compatibility. Verify that the target panel accepts plug-on neutral THQL breakers before installation.

Installation Notes

Installation must be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize the main panel and verify absence of voltage with a meter before handling any breakers or wiring. Confirm that the load center bus and neutral bar support the plug-on neutral design before installing this breaker. Conductor sizing must comply with NEC ampacity tables for the connected load and wire material.
