GV124FPB 200A 100VDC High Voltage DC Contactor

Sensata-Gigavac GV124FPB is a GV12 series High Voltage DC Contactor with 48VDC coil, PC pins, auxiliary contacts, and sealed construction.

Overview

Overview

Sensata Gigavac GV124FPB

Sensata Gigavac GV124FPB is a 200A 100VDC high voltage DC contactor from the GV12 series, designed for compact DC power switching in charging equipment, battery systems, and industrial distribution circuits. This high voltage DC contactor uses an SPST-NO contact arrangement, a 48VDC coil, PC pin termination, auxiliary contacts, and hermetically sealed construction. For OEM designs that need a reliable high voltage DC contactor with feedback capability and protected switching performance, GV124FPB provides a practical option for 100VDC-class power control.

As a sealed high voltage DC contactor, GV124FPB helps isolate the switching chamber from dust, moisture, and environmental contamination. This makes it suitable for equipment that may face vibration, temperature variation, or semi-exposed installation conditions. The 48VDC coil supports control systems that already use a 48V auxiliary supply, while built-in coil suppression helps reduce voltage transients when the coil is turned off.

Product Positioning

GV124FPB is positioned as a high voltage DC contactor for low-voltage battery and charging systems that need 200A current capacity and 100VDC switching capability. It is especially useful in EV charging support equipment, charging carts, battery charging cabinets, service disconnect modules, and industrial DC power assemblies. Compared with lower coil-voltage variants, this model is better suited to platforms that standardize on 48VDC control power.

This high voltage DC contactor is also useful where contact status feedback is required. The auxiliary contacts allow a controller to confirm whether the main contactor has changed state after a command. In charging and battery equipment, this feedback can support charge-enable logic, fault confirmation, maintenance interlocks, and system diagnostics.

Features and Benefits

The main benefit of GV124FPB is its balance of current capacity, sealed construction, and control integration. As a high voltage DC contactor, it can switch substantial DC current while remaining compact enough for OEM power-control assemblies. The normally open contact design keeps the power circuit open until the 48VDC coil is energized, which is commonly required in charging isolation, battery disconnect, and controlled DC load switching.

The hermetically sealed design protects the internal contact system from external contamination. This is important because DC switching can be sensitive to moisture, particles, and corrosive environments. A sealed high voltage DC contactor such as GV124FPB can provide more stable performance in industrial cabinets, mobile equipment, charging systems, and energy storage support equipment.

The 48VDC coil helps reduce control current compared with lower-voltage coil options. Built-in coil suppression simplifies the control circuit and helps protect PLC outputs, vehicle controllers, or embedded control boards. The auxiliary contact gives designers a simple way to monitor contactor position, making this high voltage DC contactor easier to integrate into monitored power systems.

Applications

GV124FPB is suitable for EV charging equipment, battery charging systems, industrial DC distribution, low-voltage energy storage, mobile equipment, and backup power systems. In a charging cabinet, this high voltage DC contactor may be used to connect or disconnect a charge path, isolate a battery pack, control a DC output branch, or provide a monitored switching point for fault response and service procedures.

In industrial distribution systems, GV124FPB can control DC loads, battery banks, auxiliary circuits, and protected power branches. Its sealed construction and feedback capability make it useful where operators need both rugged switching and clear status information. For mobile and battery-powered equipment, the high voltage DC contactor can support start-up sequencing, emergency disconnect, and controlled shutdown functions.

Selection Guide

Before selecting GV124FPB, confirm the system voltage, continuous current, peak current, inrush profile, and switching duty. This high voltage DC contactor is intended for 100VDC-class applications and should not be used in systems that exceed its electrical ratings. Designers should also review load type, precharge strategy, fuse coordination, thermal rise, creepage and clearance, and mechanical support.

The 48VDC coil should match the available control power. If the system uses 12VDC or 24VDC control power, another GV12 variant may be more appropriate. If feedback is required, the auxiliary contacts should be wired according to the control logic and signal rating. For charging systems, the high voltage DC contactor should be validated together with emergency stop behavior, insulation monitoring, and service disconnect requirements.

FAQ

Is GV124FPB normally open?

Yes. GV124FPB is an SPST-NO high voltage DC contactor, so the main contacts remain open until the coil is energized.

What coil voltage does GV124FPB use?

GV124FPB uses a 48VDC coil, making it suitable for equipment with a 48V auxiliary control supply.

Can GV124FPB be used in charging equipment?

Yes. GV124FPB can be used as a high voltage DC contactor in charging equipment when the voltage, current, and switching duty are within specification.

Conclusion

GV124FPB is a 200A 100VDC high voltage DC contactor with a 48VDC coil, PC pin termination, auxiliary contacts, and hermetically sealed construction. It is a strong option for EV charging, battery systems, industrial DC distribution, mobile equipment, and monitored power-control assemblies that need compact and reliable DC switching.
