Loadcenters and Circuit Breakers
Type CH Loadcenters and Circuit Breakers
Technical Data and Specifications
Ratings
Single- and two-pole CH breakers rated 15 and 20 A have
low instantaneous magnetic trip levels. The 15 and 20 A
breakers with “HM” suffix have high magnetic trip settings
recommended for circuits with inherently high inrush currents.
All Type CH breakers are marked for heating, air conditioning
and refrigeration (HACR) equipment application. Single-pole
15–20 A breakers are also suitable for switching duty (SWD).
Shunt trip coils operate on 120 Vac and require one additional
pole space per breaker.
