TE Connectivity 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.
