Product Details
Why Choose ALQ EVD250E?
High Current Switching
Rated 250 A continuous current at 200 V DC, with up to 2,000 A max cut-off capacity (at 80 V), delivering reliable high-current DC switching for EV and industrial power systems.
Long Service Life
Engineered for high-cycle operation: 200,000 mechanical cycles and up to 50,000 make cycles on capacitive load (24 V DC), reducing maintenance and replacement costs.
Wide Temperature Range
Operates from -40°C to +85°C with 5%-95% RH humidity tolerance, suitable for harsh outdoor, vehicle-mounted and industrial environments.
Vibration & Shock Resistant
Withstands 20 G sinusoidal vibration (80-2,000 Hz) and 20 G shock (1/2 sine, 11 ms), remaining stable in moving and high-vibration applications.
Reliable Silver Alloy Contact
Silver alloy contacts with typical 1 mΩ initial contact resistance. Polarity-free design enables flexible, error-proof wiring in the field.

Frequently Asked Questions
Q1: What is the voltage and current rating of the EVD250E?
A: The EVD250E is rated for 200 V DC maximum switching voltage and 250 A continuous current. It supports load voltages from 12 V to 200 V DC, making it suitable for low-to-medium voltage EV, charging and industrial DC systems.
Q2: What coil voltages are available?
A: The contactor is available with 12 V DC, 24 V DC or 48 V DC coil voltage. Choose the coil voltage that matches your battery-management system or control circuit.
Q3: What is the contact arrangement of this contactor?
A: The power contact uses an SPST-NO-DM (Single Pole Single Throw, Normally Open, Dual Make) arrangement. An optional auxiliary contact is available in SPST-NO, SPST-NC or none for status feedback.
Q4: Can the EVD250E be used in electric vehicles and energy storage systems?
A: Yes. The EVD250E is designed for electric vehicles, energy storage systems (ESS), solar inverters, DC chargers and power conversion systems. Its compact footprint and single-coil drive make it ideal for space-constrained battery cabinets.
Q5: What protection level does the EVD250E offer?
A: The EVD250E features a sealed epoxy construction with vibration resistance up to 20 G and shock resistance up to 20 G, ensuring reliable operation in moving vehicles and industrial equipment.
Q6: How do I request a quote and what is the lead time?
A: Submit your required specifications (current rating, coil voltage, auxiliary contact type, and quantity) through the inquiry form or contact us via WhatsApp. Our engineers will respond within 24 hours. Sample lead time is [to verify with factory].
