Abb thql32100 Circuit Breaker 3P 100A 240V 10kaic

Product Description

The ABB thql32100 is a 3-pole, thermal-magnetic circuit breaker rated at 100 amps and 240 volts, with an interrupting capacity of 10 kAIC. It belongs to ABB's Q-Line series, a compact 1-inch-per-pole platform designed for load centers and lighting panels in both residential and commercial installations. The breaker features a Quick-make/Quick-break operating mechanism and a non-interchangeable trip style with fixed long-time and fixed instantaneous trip functions. A common trip bar across all three poles ensures simultaneous disconnection. Licensed electricians install this device during new panel builds, service upgrades, and branch-circuit replacements.

The thql32100 fits residential and commercial load centers and lighting panels that accept Q-Line frame breakers. It supports system voltages of 120 Vac, 120/240 Vac, and 240 Vac, making it suitable for standard single-phase three-wire distribution systems commonly found in residential services and small commercial feeders. The breaker is also rated suitable for reverse feed, adding flexibility in certain panel configurations. Optional auxiliary contact and shunt trip accessories can be ordered separately for alarm or remote-trip applications, and the breaker can be configured for HID lighting panel use.

Key Features

• 3-pole configuration with common trip bar for simultaneous pole disconnection
• 100-amp continuous current rating, standard thermal-magnetic trip
• 10 kAIC interrupting rating across all supported system voltages
• Quick-make/Quick-break mechanism with easy-to-spot trip indication
• Non-interchangeable, fixed long-time and fixed instantaneous trip functions
• Rated suitable for reverse feed; compatible with auxiliary contact and shunt trip accessories

Compatibility

Designed for use in load centers and lighting panels that accept Q-Line frame circuit breakers. Compatible with 120 Vac, 120/240 Vac, and 240 Vac system voltages. Suitable for HID lighting panel applications when ordered accordingly.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify absence of voltage with a calibrated meter before handling any wiring or mounting the breaker. Torque all line and load lugs to the values specified on the breaker or panel label. Do not use this breaker as a substitute for a disconnect switch unless the installation specifically calls for a breaker-as-disconnect configuration and all code requirements are met.
