TEY145 - 45Amp Circuit Breaker

TEY145 - 45 Amp Circuit Breaker

The TEY145 is a 45-amp, single-pole molded case circuit breaker designed for your commercial and industrial electrical systems that require dependable overcurrent protection. Built with a factory-installed thermal magnetic trip unit, it responds to both prolonged overloads and short-circuit faults without the need for interchangeable trip components. Its compact size makes it a practical fit in compatible panelboards and switchboards where space is limited, while the included load-side lugs help streamline installation. Rated to interrupt 14kA at 277VAC and 65kA at 120VAC, the TEY145 is well-suited for protecting branch circuits serving lighting, equipment, and general power distribution.
