Eaton 1951 AM/R catalog 12/12/01 4:57 PM Page 6 PRECISE OVERLOAD PROTECTION — WITH HEINEMANN® HYDRAULIC-MAGNETIC CIRCUIT BREAKERS Heat-induced nuisance tripping eliminated Heinemann® hydraulicmagnetic circuit breakers offer three major advantages over thermal devices: 1. Reduces nuisance tripping caused by high ambient temperature in or near the installation. The breaker responds only to current variations, not to temperature change. 2. Assurance that 100% of the rated current will be carried. There is no such assurance with thermal devices, which may fail to carry rated current when...

Eaton 1951 AM/R catalog 12/12/01 4:57 PM Page 7 HEINEMANN® AM/R AND AM1P SERIES CIRCUIT BREAKERS TRIP CURVE EXPLANATION Tripping Specifications Breakers (in standard wallmounted position) shall hold 100% rated current. For table and ceiling mount – consult Application Engineering. Breakers may trip between 101% and 150%, must trip at 150% and above. Non-Time Delay Trip Ranges Breakers that have no deliberately imposed delay (less than 100ms) are specified as follows. 50/60 Hz or DC Breakers may trip between 101% and 125% rated load; must trip at 125% rated load and above, as shown on...
