Thomas & Betts JS360175A Molded Case Circuit Breaker

The Thomas & Betts JS360175A is a 3-pole J-Frame molded case circuit breaker (MCCB) rated 175 A at 600 VAC, with a thermal-magnetic trip designed to protect feeders, branch circuits, and motors in three‑phase commercial and industrial distributions. This unit-mount breaker uses line and load lugs and a molded insulated-case frame for compact protection in switchboards, panelboards, motor control centers, manufacturing equipment, and OEM systems operating at 50/60 Hz. Part of the Thomas & Betts JS Series (ABB), the JS360175A supports 3‑pole protection in commercial buildings, industrial plants, power distribution, and OEM machinery requiring high‑capacity circuit protection. System integrators use this breaker for new installations, equipment upgrades, preventive maintenance, and replacement of existing J‑Frame molded case breakers. Note: this model is discontinued/obsolete and is commonly available as surplus or reconditioned replacement, with common replacements including JS360150A, JS360200A, and JS360225A.
