TEYL1020B - 20Amp Circuit Breaker

TEYL1020B - 20Amp Circuit Breaker

The TEYL1020B is a 20 amp, 1-pole thermal magnetic circuit breaker with a bolt-on mounting design for compatible panelboards. It is built for your 480Y/277V class electrical systems and uses a non-interchangeable trip to provide consistent overcurrent protection throughout its service life. This breaker protects branch circuits from both overloads and short circuits by combining thermal and magnetic trip elements in a single device. The bolt-on connection helps you keep the breaker firmly secured in the panel, making it a common choice in commercial and industrial electrical equipment. With interrupting ratings of 65kA at 277VAC and 100kA at 120VAC, the TEYL1020B is suitable for applications where higher available fault current must be considered. It can be used when replacing an existing compatible breaker or during new panel installations where these electrical ratings are required.
