KHR500 High-Voltage 600 AMP Contactors
New Small, Lightweight Contactors Handle Inrush Currents Up To
4000 AMPS. KILOVAC KHR500 Contactors Provide Hermetically Sealed Solution for Hazardous Environments.

HARRISBURG, PA – TE Connectivity (TE), a world leader in connectivity, announces its new 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 I). It is capable of handling inrush currents as high as 4000 A. The new contactors are hermetically sealed for use in harsh and explosive environments.
“TE has always been focused on advancing SWaP (Size, Weight and Power) technology to help lower cost, reduce weight and size, and improve power handling capabilities,” said Earle Alldredge, product manager, Global Aerospace, Defense, and Marine, TE. “The new KHR500 high-voltage contactors are smaller and 64 percent lighter than our popular EV500 BUBBA contactors, providing more savings and flexibility to our customers.”
Configured as a single-pole, single-throw device, the contactors can handle voltages from 28 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. The contactor’s single-pole, double-throw auxiliary switch supports 3 A at 125 VRMS or 1 A at 30 VDC, and low-level signals down to 5V/10mA.
The KHR500 contactors have an integrated dual-coil electronic “cut throat” economizer. They withstand 100,000 cycles and have an operating temperature range from minus 40 Celsius to 125 Celsius. With a rugged and robust design, these new contactors are ideal for ground vehicle, marine, solar, automotive and energy storage applications.
