Thomas & Betts FS360100A Molded Case Circuit Breaker

The Thomas & Betts FS360100A Molded Case Circuit Breaker (MCCB) provides reliable three‑phase overload and short‑circuit protection for low‑voltage industrial and commercial power distribution. It is designed for use in switchboards, panelboards, motor control centers, industrial machinery, and OEM equipment, making it a common choice for new installations, preventive maintenance, and equipment upgrades among maintenance electricians, facility managers, OEM manufacturers, and system integrators. As part of the FS Series with the FS frame, this 3‑pole unit carries a 100 A rating at up to 600 VAC and delivers a 14 kA short‑circuit interrupting capacity at 480 VAC; the thermal‑magnetic trip is non‑interchangeable and provides long‑time and instantaneous (LI) trip functions. The device uses feed‑through connections with line and load side lug terminals and is intended for panelboard or switchboard mounting, with an approximate weight of 3 lb. Note that the FS360100A is listed as discontinued/obsolete, with common replacements including FS360080A, FS360125A, and FS360150A.
