描述

8-1617803-4 is a KILOVAC high-voltage DC contactor designed for demanding aerospace, defense, and marine applications requiring robust power switching capabilities. The contactor features a 600 ampere carry rating with 3300 ampere break capacity at 400 Vdc and 4000 ampere make current, supporting bidirectional load switching across voltages ranging from 28 to 1000 Vdc. It incorporates an integrated dual-coil electronic "cut throat" economizer for efficient operation and is hermetically sealed to withstand harsh environmental conditions including extreme shock, vibration, and temperature variations. The design is not position sensitive and offers a rugged, compact form factor that is up to 64% lighter than comparable models, making it ideal for weight-critical aerospace platforms, ground vehicles, energy storage systems, and solar applications.
