TEYH3025B - 25Amp Circuit Breaker

TEYH3025B - 25 Amp Circuit Breaker

The TEYH3025B is a 25 Amp, 3-pole bolt-on circuit breaker with a thermal magnetic trip unit and a non-interchangeable trip. It is rated for 480Y/277V Class systems and is commonly used in your commercial and industrial electrical distribution equipment. The bolt-on mounting method provides a secure connection inside compatible panelboards, while the thermal magnetic trip mechanism responds to both overloads and short circuits.

This breaker has an interrupting rating of 35kA at 480VAC and 65kA at 240VAC, making it suitable for applications where higher available fault current is present. Before installation, always verify that the breaker type matches the panelboard or equipment manufacturer's requirements.
