TEYH3030B - 30Amp Circuit Breaker

TEYH3030B - 30 Amp Circuit Breaker

The TEYH3030B is a 30 Amp, 3-pole bolt-on thermal magnetic circuit breaker for use in your compatible 480Y/277V Class electrical distribution equipment. It combines thermal overload protection with magnetic short-circuit protection and uses a non-interchangeable trip unit with a fixed trip setting.

This breaker has an interrupting rating of 35kA at 480VAC and 65kA at 240VAC. The bolt-on design provides a secure connection to the panel, making it suitable for replacement work as well as new installations where a TEYH breaker is specified.
