THQL32080ST1 - 80Amp Circuit Breaker

THQL32080ST1 - 80 Amp Circuit Breaker

The THQL32080ST1 is an 80-amp, 3-pole circuit breaker designed to protect three-phase electrical systems from overloads and short circuits. Built as part of the Q-Line family, this plug-on molded case breaker combines dependable circuit protection with a factory-installed 120VAC shunt trip, allowing the breaker to be opened remotely when connected to compatible control or safety systems. With a 10 kA interrupting rating at 240 VAC, the THQL32080ST1 is a practical choice for commercial and industrial power distribution applications where reliable operation is critical. The integrated shunt trip feature makes it especially useful in installations that require emergency shutdown capability, including systems tied into fire alarms, safety controls, or other remote switching devices. Its compact footprint also helps simplify installation in compatible panelboards without taking up unnecessary space. Whether you're protecting HVAC equipment, mechanical systems, distribution panels, or other three-phase loads, this breaker delivers the performance needed to help keep electrical systems operating safely and efficiently.
