Sensata Gigavac SGX151CXX

Sensata Gigavac SGX151CXX is an SGX15 series High Voltage DC Contactor designed for compact charging systems, 24V-controlled battery equipment, small ESS modules, and high-voltage auxiliary power paths. This High Voltage DC Contactor provides a 150A current rating, 750VDC rated switching voltage according to Sensata SGX151 drawing data, 24VDC coil control, SPST-NO contact arrangement, connector-style control wiring, chassis mounting, and sealed ceramic construction. For equipment that uses a 24V control platform, the SGX151CXX High Voltage DC Contactor is a compact switching choice.

The SGX151CXX High Voltage DC Contactor is similar in power class to SGX151BXX, but the coil voltage changes the best application fit. SGX151BXX is better for 12V control systems, while SGX151CXX is better for 24V charger cabinets, industrial battery modules, and compact DC control panels. This High Voltage DC Contactor gives designers a moderate-current switching device for high-voltage circuits without moving to a larger GX or GTM contactor.

Product Positioning

SGX151CXX is positioned as a compact 24V-control High Voltage DC Contactor for charger and battery support circuits. Its 150A rating makes it suitable for smaller DC branches, charger enable paths, auxiliary inverter connections, and module-level battery outputs. This High Voltage DC Contactor is useful where the cabinet already has 24V control power and the system requires sealed switching.

The application angle for SGX151CXX is compact charging equipment. A High Voltage DC Contactor in a charger cabinet can isolate a power branch, enable a controlled DC output, or disconnect a battery interface path. The 24VDC coil aligns with common industrial control rails, making the SGX151CXX High Voltage DC Contactor easy to integrate into many power electronics cabinets.

Features and Benefits

The first benefit of SGX151CXX is 24V control compatibility. Many charger cabinets, industrial battery systems, and automation power modules use 24V auxiliary power. A 24VDC coil High Voltage DC Contactor can be controlled from that platform when the driver circuit is correctly designed. This makes SGX151CXX useful for compact power cabinets.

The second benefit is compact high-voltage switching. The 150A High Voltage DC Contactor class fits moderate-current DC paths where a 350A or 600A contactor would be too large. SGX151CXX helps designers keep charger modules, service boxes, and battery support circuits smaller and easier to wire.

The third benefit is sealed ceramic construction. A High Voltage DC Contactor in a charger or battery enclosure may face dust, heat, moisture, and airflow contamination. The sealed SGX design helps protect the contact area and supports consistent switching behavior in compact equipment.

The fourth benefit is normally open operation. The High Voltage DC Contactor remains open until commanded by the control system. This supports controlled startup, charger enable logic, service isolation, and fault shutdown. In a 24V control cabinet, SGX151CXX can act as a clean and compact controlled switching point.

Applications

SGX151CXX is a strong High Voltage DC Contactor choice for compact charging systems. It can control a charger output branch, isolate a battery interface, or switch an auxiliary high-voltage circuit. In small energy storage systems, this High Voltage DC Contactor can be used for module-level isolation, service disconnect logic, or DC branch control.

In industrial DC control panels, the SGX151CXX High Voltage DC Contactor can switch moderate-current loads while the controller uses standard 24V wiring. In battery test equipment, the High Voltage DC Contactor can provide controlled connection of a 150A class path. The final selection should confirm voltage rating, load current, switching duty, coil power, connector layout, and fault protection.

Selection Guide

Select SGX151CXX when the design needs a compact 150A High Voltage DC Contactor with 24VDC coil control and SPST-NO operation. If the system uses 12V auxiliary power, SGX151BXX is the closer High Voltage DC Contactor match. If the equipment requires a higher current rating, review GX14, GX16, GV24, HX, or GTM models.
