Model JA 46 100 - 150 AMP DC Contactor

Model JA 46 DC Contactor
100 - 150 Amp Rating, Coil Voltage 12 V to 240 VDC

AMETEK Switch 46 Series DC Contactors are designed to fit a wide range of applications including electric forklift trucks, DC winches, electric vehicles, and more recently to the telecommunications industry. The 46 Series is of a modular design construction, featuring a quick assembly and disassembly with the removal of two screws. This format offers the user an easier and cost effective way to servicing. The availability of different mounting styles offers greater flexibility and with space a premium, makes this design a requirement. This 100 - 150 amp contactor is available in coil voltages from 12 V through to 240 VDC, in both continuous and intermittent duty. It is also tested to withstand a mechanical life of 3 million cycles. The AMETEK Switch 46 Series is a high-performance quality, low cost, versatile contactor with totally interchangeable contacts. With all of the above attributes, the 46 Series is a truly dependable DC contactor.

There are options available for the JA 460 Series:

  • Magnetic Blow-Outs - Normally used when switching voltages higher than 48 VDC
  • Auxiliary Switches - Available on all JA Series except the JAD and JAV styles. Rated 5 amps at 24 VDC
  • Large Contacts - Used mainly in severe applications such as pump motor switching. The suffix “L” denotes the large contacts.
