TE Connectivity’s (TE) Kilovac KHR500 “BUBBA II” features smaller size and lighter weights than our popular EV500 “BUBBA” high-voltage contactors. Capable of handling inrush currents as high 4000 A, the contactors are hermetically sealed for use in hazardous or explosive environments. Configured as single-pole, single-throw devices, the contactors can handle voltages from 28 VDC to 1000 VDC and continuous 600 A currents. Because it is not polarity sensitive, the contactor allows bidirectional load switching. An integrated coil economizer reduces the power required to hold the contacts closed to 320 mA at 24 VDC. A single-pole, double-throw auxiliary switch supports 3 A at 125 VRMS or 1 A at 30 VDC and low-level signals down to 5 V/10 mA.
