Features:
- Trip Free Action
- Waterproof Panel Integrity
- Inverse Time Delay
The Airpax AP Series Hydraulic Magnetic Circuit Protectors 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. Salt
spray testing per MIL-STD-202, Method 101, Test Condition B, with no
evidence of corrosion, electrical or mechanical damage.
Typical applications include communication, navigation and aircraft
instrumentation, radar and power supplies.
The Airpax UP circuit protector, with UL recognition and CSA
certification, is essentially the same as the AP in construction and
operating principle. It is approved for operation at 50 volts DC to 20
amperes, 120 volts 50/60Hz to 15 amperes and 240 volts 50/60Hz to 7.5
amperes. The UP circuit protector is available in single pole units only,
due to UL and CSA creepage specifications and the wide glass terminals
utilized. The UP series offers an optional FM approval (Factory Mutual
Research), provided for petrochemical applications. FM approval is
available for single pole, series trip, UP type units only. The UP circuit
protector also offers an optional ATEX certification for use in explosive
environments.
The M39019/01-239 Airpax Hydraulic Magnetic Circuit Protector may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
