TEYD3025B - 25Amp Circuit Breaker

TEYD3025B - 25 Amp Circuit Breaker

When dependable circuit protection matters, the TEYD3025B is built to do the job. This 25 amp, 3-pole thermal magnetic circuit breaker is intended for use in your 480Y/277V Class electrical systems and features a secure bolt-on design that helps you to keep the breaker firmly mounted inside compatible panelboards. The thermal magnetic trip mechanism responds to both prolonged overloads and sudden short circuits, helping protect electrical equipment from damage while supporting safe system operation.

With an interrupting capacity of 25kA at 480VAC and 65kA at 240VAC, the TEYD3025B is well suited for a variety of commercial and industrial applications where reliable overcurrent protection is essential. It also features a non-interchangeable trip, so the factory-set trip characteristics remain unchanged throughout the life of the breaker. Whether you're replacing a worn breaker or maintaining an existing electrical system, the TEYD3025B offers a straightforward solution that helps keep your equipment protected and operating as intended.
