Sensata Gigavac GV241BAX

Sensata Gigavac GV241BAX is a 400A 800VDC High Voltage DC Contactor for renewable energy disconnects, 12V-controlled battery packs, service isolation units, and compact DC power cabinets. This GV24 series High Voltage DC Contactor uses a 12VDC coil, SPST-NO main contact arrangement, flying leads, stud power terminals, chassis mounting, hermetically sealed construction, and no auxiliary contact. GV241BAX is a practical High Voltage DC Contactor when a system needs 400A switching capacity and a simple 12V control interface without built-in auxiliary feedback.

This page positions GV241BAX around renewable energy battery disconnect and no-auxiliary selection. Some GV24 models are very similar, so the distinction matters: GV241BAX combines upright chassis mounting, flying leads, 12VDC coil control, and an X suffix with no auxiliary contact. In a solar storage pack, battery service box, or DC disconnect module, this High Voltage DC Contactor can be used where the controller monitors the bus through voltage, current, or BMS logic rather than through an auxiliary contact on the contactor itself.

Product Positioning

GV241BAX is positioned as a 12V coil High Voltage DC Contactor for 400A battery and renewable energy switching. It is suitable for battery pack main disconnects, renewable energy service panels, charger isolation circuits, backup power modules, and compact DC distribution units. The High Voltage DC Contactor provides an 800VDC nominal switching class while keeping the control side compatible with 12V electronics.

Compared with 24V GV24 variants, GV241BAX is better suited to systems that use a 12V auxiliary battery or vehicle-style control supply. Compared with GV244CPX, which uses PCB pins, this High Voltage DC Contactor uses flying leads for more flexible harness routing. Compared with auxiliary-contact versions, GV241BAX is selected when no contactor feedback circuit is needed or when feedback is handled by other sensors in the equipment.

Features and Benefits

The 12VDC coil is one of the main benefits of GV241BAX. Many smaller energy storage systems, mobile battery packs, auxiliary power units, and service disconnect modules already use 12V control electronics. A 12V coil High Voltage DC Contactor allows the control design to remain simple without adding a separate 24V supply only for contactor operation.

The no-auxiliary-contact configuration can also be useful. In many battery and renewable energy systems, the controller already measures pack voltage, output voltage, current flow, or charger state. If the equipment does not need contactor auxiliary feedback, GV241BAX provides a simpler High Voltage DC Contactor configuration while keeping the same 400A GV24 switching platform.

The flying lead format gives the wiring harness more freedom than PCB pin versions. A High Voltage DC Contactor may need to sit close to a busbar or cable lug while the control harness routes to a BMS board, relay driver, service connector, or control module. Flying leads help separate mechanical placement from control-board placement. The sealed construction helps protect the High Voltage DC Contactor from dust, moisture, oxidation, and field contamination.

Applications

• Renewable energy battery disconnect circuits requiring a 400A High Voltage DC Contactor.
• Solar storage packs using 12V control power.
• Compact DC service disconnect boxes without auxiliary feedback requirements.
• Backup power and telecom-style battery systems.
• Charger isolation circuits in 800VDC-class battery equipment.
• Mobile energy modules and auxiliary DC power units.
• Industrial DC distribution panels where flying leads are preferred.

Selection Guide

Select GV241BAX when the design needs a 400A High Voltage DC Contactor, 800VDC nominal voltage class, 12VDC coil control, flying leads, sealed construction, and no auxiliary contact. If the controller requires contact-position feedback, choose a GV241BAB or GV241BAC auxiliary-contact variant. If the equipment uses 24V control power, choose a GV241C or GV244C variant. If PCB pin termination is needed, compare GV244 versions instead of this flying-lead High Voltage DC Contactor.

Before final selection, confirm continuous current, fault protection, cable size, fuse coordination, precharge sequence, coil driver capability, enclosure clearance, and service disconnect strategy. A High Voltage DC Contactor should be chosen as part of the complete battery safety design, not only by matching current and voltage values.
