SMALL, LIGHTWEIGHT HERMETICALLY SEALED CONTACTOR FOR
HARSH AND EXPLOSIVE ENVIRONMENTS
AEROSPACE, DEFENSE & MARINE /// KILOVAC KHR500 CONTACTORS
TE Connectivity’s (TE) KILOVAC KHR500 “BUBBA II” feature smaller size
and lighter weight 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.
TE Connectivity’s (TE) KILOVAC KHR500 contactors feature smaller size
and lighter weight than our popular EV500 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 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.
A single-pole, double-throw auxiliary switch supports 3 A @ 125 Vrms or
1 A @ 30 Vdc, and low-level signals down to 5 V/10 mA.
