Datasheet Summary
Powered by GS/AI

The ECK100B series high-voltage DC contactor is designed for control in high-voltage applications such as battery energy storage systems and EV charging. The part number 2071583-4 corresponds to a variant with a 12 VDC coil, bottom mount, internal thread main contact connection, and no auxiliary contacts. It is hermetically sealed with ceramic technology, supports continuous currents up to 150 A at 40 °C, and switches up to 1000 VDC. The contactor has a mechanical life of 300,000 cycles, operates within an ambient temperature range of -40 °C to 85 °C, and has an IP67 protection rating. Coil power is 5.5 W, initial contact voltage drop is ≤80 mV at 100 A, and dielectric withstand voltage is 4300 Vrms between contacts and coil. Weight is 0.18 kg, and terminals use flying leads for coil connection and M5 screws for main contacts.
