Compact high-current DC contactor body with two M6 power terminals, auxiliary contact pins and four mounting holes. Outline dimensions 104.0 × 70.0 × 107.9 mm make it suitable for battery boxes, PDU assemblies and high-voltage distribution units in EVs and energy storage systems.
Handles 1500V DC load voltage and 250A continuous current with 1500A breaking capacity, supporting systems up to 500kW switching power.
Dual-pole SPST-NO configuration lets designers switch both positive and negative rails with one compact contactor, saving space and wiring in battery packs.
Standard 12V and 24V DC coils cover common EV auxiliary power rails and BMS control voltages, with 50W coil power for reliable high-force operation.
0.3mΩ contact resistance minimizes heat generation and voltage drop at 250A, improving system efficiency and reducing cooling requirements.
At 104 × 70 × 107.9 mm, the HFE88P-250 packs 500kW switching capability into a housing suitable for space-constrained EV and ESS installations.
