Sensata Gigavac GX12CCB

Sensata Gigavac GX12CCB is a GX12 series High Voltage DC Contactor designed for compact DC power systems that need 225A current capacity, 800VDC switching voltage, 24VDC coil control, and monitored installation flexibility. This High Voltage DC Contactor uses an SPST-NO double-make main contact, flying leads, normally open auxiliary feedback, chassis mounting, and hermetically sealed EPIC construction. GX12CCB is a practical High Voltage DC Contactor for charger branches, compact battery packs, service disconnect circuits, and moderate-current inverter support paths.

The GX12CCB High Voltage DC Contactor fills the gap between smaller 150A GX11 models and larger 350A GX14 models. In many equipment designs, a 225A High Voltage DC Contactor is enough for a protected DC branch, but the system still needs an 800VDC rating and sealed construction. GX12CCB gives designers a High Voltage DC Contactor with 24V control compatibility and feedback capability for control systems that need contactor state information.

Product Positioning

GX12CCB is positioned as a moderate-current High Voltage DC Contactor for compact charger and battery interface systems. It is not a 600A traction contactor and not a low-voltage MX product. GX12CCB fits equipment where the switched path is higher than a small relay can support, but where a larger High Voltage DC Contactor would add unnecessary size and cost.

The main application angle for GX12CCB is compact charging and service disconnect equipment. A High Voltage DC Contactor in this role may switch a charger output, isolate a battery module, control a protected DC load, or provide a service disconnect point. The 24VDC coil makes GX12CCB suitable for industrial controllers, charger boards, BMS outputs, and safety circuits that use 24V auxiliary power.

Features and Benefits

The first benefit of GX12CCB is the 225A current class. A 225A High Voltage DC Contactor can support moderate-current DC switching without using a larger 350A or 600A package. This helps compact charger modules, battery disconnect boxes, and smaller inverter assemblies stay easier to package.

The second benefit is 24V coil compatibility. Many battery systems, charging modules, and industrial control panels use a 24V auxiliary supply. A 24VDC High Voltage DC Contactor can integrate into those platforms without adding a separate coil power rail.

The third benefit is normally open auxiliary feedback. A High Voltage DC Contactor with NO auxiliary feedback can help a controller confirm whether the contactor has closed before enabling charge, discharge, precharge completion, or service release. This makes GX12CCB useful in systems that require monitored switching logic.

The fourth benefit is sealed EPIC construction. A High Voltage DC Contactor installed in a charger, battery cabinet, or mobile module may face dust, humidity, vibration, and temperature change. The sealed GX12 body helps protect the switching chamber and supports dependable service.

Applications

GX12CCB is commonly used as a High Voltage DC Contactor in compact charging equipment. It can switch a charger output branch, isolate a battery interface, or control a moderate-current high-voltage path. The GX12CCB High Voltage DC Contactor is also suitable for battery service boxes where feedback is required.

In energy storage and industrial equipment, this High Voltage DC Contactor can be used in modular DC distribution, small inverter support circuits, battery test fixtures, DC UPS modules, and protected load branches. The High Voltage DC Contactor should be coordinated with fuses, precharge design, insulation monitoring, thermal limits, and controller timing.

Selection Guide

Select GX12CCB when the design needs a 225A High Voltage DC Contactor with 800VDC switching capability, 24VDC coil control, flying leads, and normally open auxiliary feedback. If the system requires no auxiliary contact or NC auxiliary feedback, choose the matching GX12 suffix. If the current requirement is 350A or higher, review a GX14, GX16, or GV series High Voltage DC Contactor.

Before installation, confirm voltage rating, current profile, coil driver capacity, auxiliary logic, lead routing, cable clearance, mounting space, and thermal conditions. A High Voltage DC Contactor should be validated with the complete DC circuit and protection design.
