Sensata Gigavac GX110BEB

Sensata Gigavac GX110BEB is a 1000A 800VDC High Voltage DC Contactor from the GX110 EPIC series, designed for electric ferry propulsion, heavy marine battery systems, large mobile energy platforms, and megawatt-class DC power assemblies. This High Voltage DC Contactor uses an SPST-NO-DM main contact form, a 12VDC internal coil, stud power terminals, an 8-pin Deutsch connector, chassis or flange mounting, SPST-NO auxiliary contact functionality, and hermetically sealed construction. It is intended for systems where extremely high current capacity, connectorized control wiring, and sealed switching reliability are required in an 800VDC-class architecture.

GX110BEB is positioned above 600A GX16 and 500A GV200 contactors because it supports a 1000A current class. That makes it suitable for propulsion battery outputs, high-current DC bus tie points, large inverter feeds, shore-power battery interfaces, and heavy-duty DC distribution links. The EPIC sealed construction helps protect the contact system from dust, humidity, vibration, and contamination, which is important in marine power rooms, vehicle battery compartments, and industrial energy modules.

Product Positioning

GX110BEB should be positioned as a high-current High Voltage DC Contactor for electric ferry propulsion and large mobile battery platforms. Compared with GX16CEB, this model provides a much higher 1000A rating. Compared with HX series 1500VDC contactors, GX110BEB is better suited when the design priority is very high current at up to 800VDC rather than maximum voltage headroom.

The 12VDC internal coil is useful for equipment that keeps 12V auxiliary control available for service logic, pilot relays, interlock circuits, or marine control electronics. The 8-pin Deutsch connector supports cleaner harness integration than loose control leads, and the SPST-NO auxiliary contact gives the controller a feedback signal for contactor state confirmation.

Features and Benefits

The main benefit of GX110BEB is its 1000A current capability. A High Voltage DC Contactor in this class can control very large battery outputs, propulsion inverter feeds, DC bus sections, and high-current charging paths where 350A, 500A, or 600A devices would not provide enough margin.

The 12-800VDC switching range supports large battery architectures used in marine propulsion, industrial electrification, and mobile energy systems. GX110BEB is especially relevant when the system carries very high current and still needs a sealed contactor designed for elevated DC voltage.

The 8-pin connector improves control-side integration. Connectorized wiring can reduce assembly variation, simplify service replacement, and make harness routing cleaner in marine or industrial equipment where maintenance access matters. The auxiliary contact can be routed through the same control interface for supervised operation.

The SPST-NO auxiliary contact supports monitored switching. A controller can compare the coil command with contact feedback before enabling propulsion drives, closing a charger path, or energizing a DC bus. This can help with interlock logic, start-up sequencing, fault detection, and controlled shutdown.

Hermetically sealed EPIC construction helps maintain reliable switching in demanding environments. Marine equipment and large mobile battery systems may face vibration, humidity, salt-air exposure, and long duty cycles. A sealed High Voltage DC Contactor helps protect the internal contact chamber and supports stable operation across extended service intervals.

Applications

GX110BEB is especially suitable for electric ferry propulsion and heavy marine battery systems. In an electric ferry or workboat power room, this High Voltage DC Contactor can connect a propulsion battery string, isolate a main inverter feed, switch a DC bus tie, or disconnect a high-current branch during service and fault events.

The contactor can also be used in megawatt mobile energy storage, industrial electrification skids, large charger cabinets, heavy-duty vehicle platforms, marine DC distribution, and high-current backup power systems. Its 1000A current rating makes it appropriate for applications where smaller GX, GV, or HX models would be undersized.

Selection Guide

Before selecting GX110BEB, confirm maximum DC bus voltage, continuous current, peak current, inrush current, switching duty, and fault strategy. This High Voltage DC Contactor is intended for very high current paths, so cable or busbar sizing, thermal rise, fuse coordination, precharge design, and enclosure ventilation must be reviewed carefully.

The coil supply should be a stable 12VDC source. Designers should verify the 8-pin connector pinout, auxiliary contact wiring, coil driver capability, stud terminal clearance, mounting orientation, vibration exposure, and service access. If the design needs lower current, GX16 or GV200 models may be more compact. If the design needs 1500VDC voltage capability, HX series contactors should be reviewed.
