150 amp contactor for AC or DC

11 July 2007 Circuit & System Protection

Gigavac has released its new multipurpose sealed contactor for switching from 12 to 750 volts AC or DC at 150 amps.

Important features of this new contactor are:

* Chassis level UL508 sized power terminals - no need for specially routed power cables, special bus bars, or special lugs.

* Rugged EPICTM Seal rated to 175°C - Same technology used for advanced aerospace programs that reduce risk of fire or meltdown in over current conditions.

* Hermetically sealed - approved for use in hazardous locations and for temporary water immersion.

* Electronics-free high efficiency coil - no EMI emissions or cross-talk on your system control power.

* Built-in coil suppression - saves engineering time and parts cost to add external coil suppression.

* Stainless steel hardware and mounting inserts, for years of corrosion free service.

* UL508 ambient compliant to 75°C but can operate continuously at 85°C with higher terminal temperature rise of 60°C. Can also operate up to 125°C in special cases.

* Not position sensitive - can be mounted in any position for ease of installation.

Applications include: electric vehicles, welding equipment, railway rolling stock auxiliaries, fork-lift trucks, telecommunications, battery back-up systems, UPS, marine winches and motors, engine starting systems, etc.
