TEY140 - 40Amp Circuit Breaker

TEY140 - 40 Amp Circuit Breaker

The TEY140 is a 40 amp, single-pole molded case circuit breaker built for commercial and industrial electrical systems that require dependable overcurrent protection. It uses a fixed (non-interchangeable) thermal magnetic trip unit, allowing it to respond to both sustained overloads and short-circuit faults. Its compact size makes it a practical option when panel space is limited, and the included load-side lugs help simplify installation. With an interrupting rating of 14kA at 277VAC and 65kA at 120VAC, the TEY140 is well suited for protecting branch circuits serving lighting, HVAC equipment, machinery, and other electrical loads. Whether you're replacing an existing breaker or maintaining industrial equipment, this breaker provides the performance expected from the TEY product line.
