AP/UP, AP/MIL Series Hydraulic Magnetic Circuit Protectors
INTRODUCTION
The Airpax™ AP series are fully sealed, magnetic circuit
protectors that combine power switching and accurate, reliable
circuit protection with inverse time delays and trip free features.
Unlike a thermal circuit protector, the AP does not change its
trip current over a wide temperature span. In addition, the AP
magnetic circuit protector is available in either DC, 50/60Hz or
400Hz versions and with various delays to match the protector to
specific application requirements.
One of the most important features of this protector is the “trip
free” action, which means the circuit will not remain closed in
the presence of an overload even though the handle is held in
the ON position. The delay mechanism senses the fault and the
contacts open.
Waterproof panel integrity is provided by an “O” ring bushing
seal and a silicon rubber gland within the bushing/handle
assembly. |
