Type BR and CH Surge Breakers

Product Description

The CH and BR surge
breaker is designed to
provide premier AC power
surge protection for sensitive
electronics and appliances
from the damaging effects of
electrical surges. In addition,
the surge breaker is a
functional two-pole thermal
magnetic breaker.

The combination of circuit
protection and surge
protection provides extra
flexibility and space saving in
the loadcenter.

Product Features

●

Complete home surge
protection for all circuits
plus a functional two-pole
thermal magnetic breaker

●

LEDs provide protection
status

●

Plug-on connection to the
busbar provides superior
protection and easy
installation for new
construction or renovation

●

Eliminates the potential for
incorrect installation of
externally mounted surge
devices—(longer “lead”
lengths can reduce
protection levels)
