Gigavac GV200FC Contactor - 48 V internal coil suppression
Internal coil economizer circuits can interfere with controllers that directly control the contactor such as Sevcon.
Gigavac GV200FC Contactor - 48 V internal coil suppression
GIGAVAC's GV Series contactors are among the most cost-effective, high-performance sealed power contactors on the market. Most customers require a sealed solution when specifying a contactor that supports switching large DC loads . With rated voltages between 48Vdc and 800Vdc, GIGAVAC GV series contactors are designed to switch loads greater than 400 amps and interrupt short-circuit currents at 3500 amps ( depending on voltage). Like all GIGAVAC advanced switching solutions , these contactors can be mounted in any axis or orientation and are sealed to withstand virtually any environment. difficult. All GIGAVAC GV series power contactors comply with RoHS and CE compliance requirements.

Question & Answer:
Q :
Good morning,
I have a problem with a gigavac type contactor which I think I bought from you.
When I connect the control circuit to 12V (auxiliary vehicle battery), the contactor gets very hot. I have measured more than 60ºC temperature.
I understand that it is the coil that heats up.
It heats up without having any load in the power circuit.
I understand that this is not normal. Can you tell me how to prevent the contactor from getting so hot?
Thanks for the information
