Overview

The ABB THQL31WY15 Molded Case Switch Breaker is a 3-pole, 15 Ampere (A) circuit protection device rated for 240 Volts (V) AC, designed by ABB Electrification for industrial and commercial electrical systems. This breaker provides precise overcurrent protection with a 10 kAIC (kiloamperes interrupting capacity) rating, enabling safe interruption of fault currents up to 10,000 Amperes to prevent equipment damage and ensure personnel safety in high-fault environments. Built, tested, and listed to UL 489 and cUL standards, the THQL31WY15 complies with North American safety regulations and is certified for use as a main device in panelboards and switchboards. It is not suitable for subfeed or branch breaker applications due to the absence of wire protection. Key features include thermal-magnetic tripping for reliable performance during high in-rush currents, such as motor startups, large lighting systems, or HVAC installations. The fixed thermal and magnetic thresholds eliminate calibration delays, enabling rapid deployment. The breaker’s compact design and bolt-on mounting (where applicable) simplify installation in constrained spaces. Compatible with standard 240V power distribution systems, the THQL31WY15 is a cost-effective solution for protecting critical infrastructure in commercial buildings, industrial facilities, and utility applications. Its 10,000 ampere symmetrical short circuit withstand rating ensures compatibility with protective devices rated 10,000 amperes IC or greater, provided the ampere rating does not exceed that of the switch. Line and load lugs are included in the basic switch ordering code. Trust ABB’s legacy of reliability to maintain operational continuity while reducing downtime risks associated with electrical faults. The THQL31WY15 is manufactured in the US, ensuring adherence to stringent quality and safety standards.
