CHB270 - 70Amp Circuit Breaker

CHB270 - 70 Amp Circuit Breaker

The CHB270 circuit breaker is a 2-pole, 70-amp bolt-on breaker designed for use in compatible CHB panelboards and distribution systems operating at 120/240VAC. Built for dependable overcurrent protection in residential and light commercial electrical systems, this breaker provides a 10k A.I.C. interrupting rating to help protect circuits from damage caused by overloads and short circuits. Its bolt-on mounting style ensures a secure, stable connection to the panel bus, helping maintain proper electrical contact in applications where reliability and fit are critical. Designed for straightforward installation and consistent operation, the CHB270 is manufactured to meet industry standards and is built to last in demanding environments.
