TEYL3025B - 25Amp Circuit Breaker

TEYL3025B - 25 Amp Circuit Breaker

The TEYL3025B is a 25 Amp, 3-pole thermal magnetic circuit breaker with a bolt-on mounting design for secure installation in compatible electrical distribution equipment. Built for 480Y/277V Class systems, it helps protect branch circuits from overloads and short circuits using a fixed, non-interchangeable trip unit. With an interrupting rating of 65kA at 480VAC and 100kA at 240VAC, this breaker is well suited for applications where higher fault current ratings are required.

Whether you're replacing an existing breaker or maintaining commercial or industrial electrical equipment, the TEYL3025B delivers the performance expected from the TEYL series. The bolt-on connection helps provide a solid electrical and mechanical fit, making it a practical choice for panelboards and other power distribution equipment that depend on reliable circuit protection.
