Contactors, High Voltage 600 AMP
Contactors, High Voltage 600 AMP
TE Connectivity (TE), a world leader in connectivity, has announced 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. Configured as a single-pole, single-throw device, the contactors can handle voltages from 28 to 1000 V DC 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 V DC. The contactor’s single-pole, double-throw auxiliary switch supports 3 A at 125 VRMS or 1 A at 30 V DC, and low-level signals down to 5 V/10 mA. 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°C to 125°C. With a rugged and robust design, these new contactors are ideal for ground vehicle, marine, solar, automotive and energy storage applications.
