GIGAVAC GV351RPBX High-Voltage DC Contactor

The GIGAVAC GV351RPBX High-Voltage DC Contactor is a premium, ultra-reliable electrical switching device engineered for advanced electric vehicles (EVs), renewable energy systems, and heavy-duty industrial applications. Manufactured in Mexico by GIGAVAC (a Sensata Technologies brand), this gas-filled, hermetically sealed contactor is designed to safely handle a massive 500 Amps of continuous current at up to 1000V DC.

Key Specifications:

• Category: Automotive Parts & Accessories / EV High Voltage Components / DC Contactors & Relays

• Origin: Made in Mexico (CAGE Code: SEK19)

Key Features:

• Gas-Filled Hermetic Seal – The internal switching chamber is hermetically sealed and filled with a specialized suppression gas. This prevents contact oxidation, provides significantly lower contact resistance (less heat), and actively extinguishes the massive electrical arcs generated when breaking a 1000V DC circuit.

• Integrated Auxiliary Contacts – The 4-pin socket includes connections for an SPST-NO (Single Pole Single Throw - Normally Open) auxiliary circuit. This provides crucial physical feedback to the vehicle's Battery Management System (BMS), verifying exactly when the main high-voltage contacts have successfully opened or closed.

• Physical Arc Barrier – Features a molded plastic divider sitting directly between the main positive and negative high-voltage terminals to prevent high-voltage flashover or arcing across the top of the unit.

• Severe-Duty Mounting – Features a flanged "Upright Mount" base with pre-installed brass crush-sleeves, allowing the unit to be bolted tightly to a battery box or chassis without fracturing the plastic housing under heavy road vibrations.

Ideal For:

• Main battery pack isolation in commercial Electric Vehicles (EVs), buses, and high-performance racing EVs

• Grid-scale solar array (PV) inverters and high-capacity Battery Energy Storage Systems (BESS)

• Megawatt-scale DC Fast Charging stations and EVSE infrastructure

• Heavy-duty marine and aerospace high-voltage power distribution
