Industry Technical Advantages

Full-Load Current Carrying Capacity in High-Temperature Environments

Optimized heat dissipation channel design supports continuous full-load operation even in vehicle compartments or enclosed charging station cabinets at temperatures as high as 85°C.

Compact and Lightweight Design

Small size and light weight facilitate high-density deployment within vehicle PDU distribution boxes and compact charging station arrays.

Electronic Energy-Saving Coil Control

Utilizes intelligent dual-coil drive technology, with a holding power consumption of less than 3W–5W when closed, significantly reducing heat generation and wiring harness load.

Electrical Lifespan Adapted for High-Frequency Switching

Designed for the harsh operating conditions of commercial fast-charging stations—where plugs are frequently inserted and removed tens of thousands of times annually—it features extended contact wear resistance.

Manufacturing and Rigorous Testing

Automotive-Grade Automated Assembly Line

Robotic arms at core workstations perform automatic assembly and riveting, eliminating tolerances associated with manual assembly.

High-Frequency Electrical Life Durability Testing

Simulates fast-charging cycles to validate tens of thousands of load-carrying make-and-break cycles.

100% Automatic Detection of Operating Parameters

An automated test bench inspects each unit individually to verify consistency in engagement voltage, release voltage, and contact resistance.

Selection Guide

Charging Station Power and Continuous Current

For 120 kW–180 kW, select 200 A–250 A; for 360 kW–600 kW liquid-cooled ultra-fast charging, select 400 A–600 A.

Voltage Rating Classification

Mainstream 450V DC platforms for passenger vehicles vs. electric heavy-duty trucks and 800V high-voltage platforms (requiring 900V–1000V specifications).

Vehicle On-Board Pre-Charge Relay Coordination

Used in conjunction with the main contactor to connect the pre-charge resistor before the main contacts close, thereby eliminating capacitive inrush current.

Environmental Derating Calculation

Based on the actual internal temperature of the charging station under intense summer sunlight, calculate the thermal margin according to the product’s derating curve.
