General Electric THQB1120 Circuit Breaker With Auxiliary Switch

General Electric THQB1120 circuit breaker with auxiliary switch is a 1-pole overcurrent protection device that pairs the main breaker with an auxiliary contact (model TQAS2A1 AUX). The THQB1120 designation identifies the primary breaker unit, while the auxiliary switch provides a secondary contact for signaling or remote control tasks, enabling status indication without interrupting the main current path. This configuration interrupts a single conductor to protect connected wiring and equipment from overloads and short circuits, and the auxiliary contact can be wired to monitoring or control circuits as needed. The associated accessory, TQAS2A1 AUX, specifies the auxiliary switch component shipped with or designed for this unit. Common applications include panels where a secondary contact is required for status feedback or simple signaling in electrical control schemes that rely on breaker status. This product pairing—GE THQB1120 breaker with its auxiliary switch accessory—offers a precise, plug-for-use solution when a single-pole protective device with an auxiliary contact is needed.
