Overview

The ABB THQL32040ST1 is a 3-pole shunt trip circuit breaker from ABB Electrification, designed for reliable overcurrent protection and remote power disconnection. This breaker features a 40A ampere rating and a 10kAIC interrupting rating at 240V. Engineered with a factory-installed 120 Vac shunt trip pole module and common trip functionality, the THQL32040ST1 allows for remote tripping of the breaker. This capability is achieved through integration with a momentary or maintained pushbutton, enabling the de-energization of all poles when the breaker is in the open or tripped state. This feature is critical for applications requiring rapid, remote power shut-off for safety compliance or emergency situations, eliminating the need for direct manual intervention at the breaker panel. Built, tested, and listed to UL and cUL standards (UL 489), this circuit breaker ensures adherence to stringent safety and performance requirements. The THQL32040ST1 occupies 4 pole spaces in a load center and is compatible with standard THQL load centers. It is suitable for protecting branch circuits powering lighting systems, HVAC equipment, and machinery controls that require medium-duty protection. Key specifications include: * **Manufacturer:** ABB - Electrification * **SKU:** THQL32040ST1 * **Poles:** 3 * **Amperage Rating:** 40 A * **Voltage Rating:** 240 V * **Interrupting Rating:** 10 kAIC * **Shunt Trip Voltage:** 120 Vac * **Standards:** UL and cUL (UL 489) * **Mounting:** Occupies 4 pole spaces * **Country of Origin:** US The common trip feature ensures that all poles de-energize simultaneously when the breaker is opened or tripped, providing comprehensive circuit isolation. The US-made THQL32040ST1 offers a dependable solution for electrical distribution systems requiring enhanced control and safety features in industrial and commercial settings.
