TE Kilovac KHR500 High Voltage 600 Amp Contactors

Kilovac KHR500 Contactor

TE Connectivity (TE) introduces the KILOVAC KHR500 "BUBBA II" high-voltage, high-rupture, 600 AMP contactor that is smaller, lighter and switches significantly higher power than its predecessor, the EV500 "BUBBA". This new contactor is capable of handling inrush currents up to 4000A and are hermetically sealed for use in harsh and explosive environments. Configured as a single-pole, single-throw device, this contactor can handle voltages from 28 to 1000 VDC and continuous 600A current. Because it is not polarity sensitive, the KILOVAC KHR500 contactor allows bidirectional load switching. An integrated coil economizer reduces the power required to hold the contacts closed to 320 mA at 24 VDC.

The contactor's single-pole, double-throw auxiliary switch supports 3A at 125 VRMS or 1A at 30 VDC, and low-level signals down to 5V/10mA. The KILOVAC KHR500 contactor offers an integrated dual-coil electronic "cut throat" economizer, and can withstand 100,000 cycles, operating from -40° to 125°. With its rugged and robust design, the KILOVAC KHR500 contactor is ideal for ground vehicle, marine, solar, automotive and energy storage applications.
