Enclosed AC Contactors for Military Applications
The AMETEK Switch 250 - 350 AMP contactor was first designed to meet the environment requirements of military applications. After thorough testing, the basic design was modified to provide a lower cost contactor for commercial generator set applications. These sealed explosion-proof contactors are designed for any standard 3-phase load as well as standard DC ampere loads.
All models feature compact size. The square base measures a maximum 4.80” on each side, and overall height is only 5.55” maximum.
The electrical design and construction of these contactors incorporate the standard AMETEK Switch quality features of our heavy-duty industrial DC contactors.
Other Special Features:
- The contactors are gasket-sealed and vented, and designed to meet all environmental requirements of MIL-R-6106.
- The contactor for commercial application is a modified version of the military model. It also meets the sealed and vented enclosure requirements for explosion-proof operation.
- The actuators of these contactors use precision tooled iron parts currently in large volume DC contactor production.
- All contactors are brazed to copper bridges and bus bars, and are silver plated for maintenance-free operation.
- Heavy=duty solid state rectifier module for AC input coil power is available.
- Heavy-duty environmental resistant coils are designed for efficient, quiet operation and a long service life.
- Proven phase barrier materials are employed for maximum safety during operation.
- Interlock switches are available for control circuit switching.
