TE Connectivity EVC 250-800 Main Contactor

The TE Connectivity EVC 250-800 Main Contactor (Model V23720-A0101-B001) is a highly advanced, heavy-duty electrical switching device engineered for the most demanding high-voltage electric vehicle (EV) and commercial energy applications. Manufactured in Portugal by TE Connectivity, this rugged contactor is designed to safely handle up to 800V DC and a continuous current of 250 Amps, acting as the critical safety gatekeeper between a high-voltage battery pack and the vehicle's drivetrain.

Key Features:

• Gas-Free Arc Suppression – Unlike traditional hermetically sealed, gas-filled contactors, the EVC 250 series innovatively uses optimized switching dynamics, expanded contact gaps, and high-performance arc-suppressing magnets to extinguish dangerous electrical arcs. This entirely eliminates the risk of internal gas leakage or pressure loss over the component's lifetime.

• Massive Short-Circuit Tolerance – Engineered for extreme safety, this contactor can withstand massive short-circuit spikes of up to 6,000 Amps for 20 milliseconds, ensuring it remains intact long enough for the system's main high-voltage fuse to blow in the event of a catastrophic fault or crash.

• Safe Galvanic Isolation – Provides absolute physical separation of the high-voltage circuit when the vehicle is turned off, ensuring the system is safe for technicians to service.

• Severe-Duty Construction – Housed in thick, flame-retardant glass-fiber reinforced plastic (PA-GF / PBT-GF). It features heavy-duty side mounting flanges equipped with metal crush sleeves, allowing it to be securely bolted to a chassis without cracking under heavy vibrations.

Ideal For:

• Main battery pack contactors in factory Electric Vehicles (EVs), commercial electric trucks, and buses

• High-performance EV conversions and motorsport electric drivetrains

• DC Fast Charging stations and EVSE infrastructure

• Solar array (PV) inverters and high-capacity Battery Energy Storage Systems (BESS)
