TEYH2020B - 20Amp Circuit Breaker

TEYH2020B - 20 Amp Circuit Breaker

If you need a 20-amp, 2-pole bolt-on circuit breaker for a compatible 480Y/277V Class panelboard, the TEYH2020B is a dependable choice. It uses a thermal magnetic trip mechanism to protect electrical circuits from overloads and short circuits and comes with a non-interchangeable trip unit. The bolt-on design provides a secure connection, helping keep the breaker firmly in place after installation. With an interrupting capacity of 35kA at 480VAC and 65kA at 240VAC, this breaker is intended for applications where higher fault current ratings are required. It's commonly used when replacing an existing breaker during maintenance, repairing electrical distribution equipment, or servicing commercial and industrial power systems. Before installation, always confirm compatibility with your panelboard and electrical system.
