TEYH1025B - 25 Amp Circuit Breaker

TEYH1025B - 25 Amp Circuit Breaker

When you need dependable circuit protection for a commercial or industrial electrical system, the TEYH1025B is built to do the job. This 1-pole, 25-amp thermal magnetic circuit breaker is designed with a bolt-on connection, helping it stay firmly mounted in compatible panelboards. It uses a non-interchangeable trip design, so the factory trip setting stays exactly as intended throughout the life of the breaker. Rated for 480Y/277V class systems, the TEYH1025B provides protection against both overloads and short circuits. It carries an interrupting rating of 35kA at 277VAC and 65kA at 125VAC, making it a solid choice for many commercial buildings, industrial facilities, schools, and similar applications. Whether you're replacing a worn breaker during routine maintenance or matching an existing installation, this model offers the performance and reliability electricians have come to expect from the TEYH product line.
