Sensata Gigavac GV200CBB-1

Sensata Gigavac GV200CBB-1 is a 500A 800VDC High Voltage DC Contactor for energy storage main disconnect systems, battery rack outputs, high-current DC distribution, and service isolation circuits. This GV200 series High Voltage DC Contactor uses a 24VDC coil, SPST-NO main contact arrangement, auxiliary contacts, stud terminals, wire leads, chassis mounting, and hermetically sealed construction. GV200CBB-1 is designed for systems that need a High Voltage DC Contactor with higher current capacity than 350A platforms while keeping a practical panel-mount format.

This product page is written around ESS main disconnect service. In an energy storage cabinet, the High Voltage DC Contactor is often part of the main positive or main negative path. It works with the BMS, fuses, precharge contactor, current sensor, and service disconnect hardware. GV200CBB-1 gives designers a 500A High Voltage DC Contactor that can be controlled from a 24V system and monitored through auxiliary contacts.

Product Positioning

GV200CBB-1 is positioned as a 24V coil High Voltage DC Contactor for 500A battery and DC bus circuits. It is suitable for containerized ESS, cabinet-level battery packs, high-current charger interfaces, backup power units, and industrial DC power assemblies. The key value of this High Voltage DC Contactor is its combination of 500A capacity, 800VDC switching class, sealed construction, and feedback capability.

Compared with compact 350A models, GV200CBB-1 provides additional current margin for main disconnect paths. Compared with very large contactors, this High Voltage DC Contactor remains practical for cabinet layouts where stud terminals and wire leads are preferred. The 24VDC coil matches common industrial and energy storage control systems, so the High Voltage DC Contactor can be driven by the same auxiliary power layer used for relays, controllers, and safety modules.

Features and Benefits

The 500A rating is the central advantage of GV200CBB-1. A main battery disconnect or DC bus isolation point often carries more current than branch circuits, so the High Voltage DC Contactor must be selected with enough margin for the full operating profile. GV200CBB-1 supports these higher-current paths while staying within the GV200 800VDC platform.

The auxiliary contacts help the system controller verify contactor state. In an ESS cabinet, the BMS should know whether the High Voltage DC Contactor is actually open or closed before allowing charge, discharge, or maintenance actions. Feedback from the auxiliary contact can support startup checks, shutdown confirmation, and fault logic.

The hermetically sealed construction protects the contact chamber from moisture, dust, oxidation, and contamination. Energy storage cabinets may face temperature cycling, site humidity, transport vibration, and long operating hours. A sealed High Voltage DC Contactor such as GV200CBB-1 is better suited to this environment than an open device. Stud terminals provide robust power cable connection, while wire leads simplify control wiring inside the cabinet.

Applications

• Energy storage system main disconnect circuits requiring a 500A High Voltage DC Contactor.
• Battery rack positive or negative main contactor positions.
• Industrial DC distribution panels with 24V control power.
• Backup power cabinets and UPS battery isolation systems.
• High-current charger interface and battery test equipment.
• Renewable energy storage cabinets using monitored DC switching.
• Service disconnect systems where auxiliary feedback is required.

Selection Guide

Select GV200CBB-1 when the design needs a 500A High Voltage DC Contactor, 800VDC capability, 24VDC coil control, auxiliary contact feedback, and sealed construction. If the circuit only requires 350A, a smaller GX or HX model may be easier to fit. If the system requires 1500VDC operation, compare an HX series High Voltage DC Contactor instead. If the control voltage is 12V or 48V, confirm the correct GV200 coil suffix before purchase.

For ESS use, confirm current rating, fault protection, precharge sequence, cable size, busbar clearance, BMS input logic, and thermal layout. The High Voltage DC Contactor should be selected as part of the full DC protection strategy, not only by matching the current number on the product title.
