DC Contactors JC46 Tabs

		Model JC 46 250 - 350 AMP DC Contactor

250 - 350 Amp Rating, Coil Voltage 12 V to 240 VDC

JC 46 Series contactor is rated at 250 - 350 amps. This versatile unit is available in coil voltages from 12 V through to 240 VDC. It can be mounted in pairs or a triple assembly on a bracket, together with interconnecting electrical links to suit customer needs. The JCM type has a built-in failsafe. If both coils are energized simultaneously, the contact design creates an open circuit.

There are options available for the JC 46 Series:

Magnetic Blow-Outs - Normally used on all inductive load applications and on resistive loads when switching voltages higher than 48 VDC
Auxiliary Switches - Available on the JC Series and 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.
