Sensata Gigavac HX22CCC

Sensata Gigavac HX22CCC is a 300A 1500VDC High Voltage DC Contactor from the HX22 series, designed for charger cabinets, high-voltage DC output stages, battery interface panels, and compact power conversion equipment. This High Voltage DC Contactor uses an SPST-NO-DM main contact form, a 24VDC coil, stud power terminals, flying lead control termination, chassis or upright mounting, auxiliary contact functionality, and hermetically sealed construction. It is a practical choice for systems that need 1500VDC-class switching with a smaller current rating than 350A or 400A HX contactor platforms.

HX22CCC is useful when a charger or power cabinet needs high voltage capability, monitored switching, and flexible lead routing. The 300A rating supports substantial DC output paths while keeping the package focused for equipment that does not require a larger HX21 or HX24 current class. The sealed HX22 construction helps protect the internal contact system from moisture, dust, and contamination, supporting reliable operation in industrial cabinets, charging systems, and high-voltage battery equipment.

Product Positioning

HX22CCC should be positioned as a 24V coil High Voltage DC Contactor for charger cabinets and 1500VDC-class DC power modules. Compared with GV24 contactors, which are commonly used in 800VDC-class systems, HX22CCC provides higher voltage capability for modern charging and power conversion designs. Compared with HX21CAC or HX241CAC, this model is better suited when the required current path is around 300A and the design benefits from a more focused HX22 configuration.

The auxiliary contact makes this High Voltage DC Contactor suitable for supervised switching. A controller can compare coil command with contact feedback before enabling charger output, closing a downstream contactor, or allowing a high-voltage bus to energize. In monitored charger cabinets, this feedback can support precharge sequencing, fault detection, service lockout, and controlled shutdown behavior.

Features and Benefits

The main advantage of HX22CCC is its 1500VDC voltage capability in a 300A contactor configuration. A High Voltage DC Contactor in this class can support charger outputs, battery interface circuits, inverter DC links, and high-voltage distribution branches where 800V contactors may not provide enough design margin.

The 24VDC coil matches common industrial and charging-system control supplies. Many charger cabinets and power conversion systems use 24VDC for controllers, sensors, fans, relays, and contactor coils. Selecting HX22CCC can simplify auxiliary power design because the contactor can operate from the same 24V control architecture used elsewhere in the equipment.

The auxiliary contact supports monitored operation. Instead of relying only on coil command, the control system can verify whether the High Voltage DC Contactor has changed state. This is useful for charger enable logic, insulation monitoring sequences, precharge routines, and fault diagnostics. For safety-related systems, the auxiliary contact should be wired and validated according to the complete control design.

Stud terminals provide secure high-current connection points for cables or busbars. Flying leads allow the coil and auxiliary circuits to route back to the controller without forcing the contactor to sit directly beside a control board. This makes HX22CCC suitable for cabinet layouts where the power section and low-voltage control section are separated.

Hermetically sealed construction helps protect the internal switching chamber from environmental contamination. Charging cabinets, industrial enclosures, and power conversion equipment may face humidity, dust, vibration, and temperature cycling. A sealed High Voltage DC Contactor helps maintain stable switching behavior across long service intervals.

Applications

HX22CCC is especially suitable for charger cabinets and 1500VDC-class charging support equipment. In a DC charging system, this High Voltage DC Contactor can switch the charger output, isolate a high-voltage branch, control a battery interface, or disconnect the DC path during service and fault conditions. The 300A rating is appropriate for charger designs that need strong current capability without moving to a larger 400A contactor.

The contactor can also be used in battery energy storage systems, inverter interfaces, renewable energy conversion equipment, high-voltage DC distribution, and industrial power cabinets. In these applications, HX22CCC may function as a branch contactor, charger interface contactor, inverter input contactor, or monitored isolation device depending on the system architecture.

Selection Guide

Before selecting HX22CCC, confirm maximum DC bus voltage, continuous current, peak current, inrush current, switching frequency, and expected duty cycle. This High Voltage DC Contactor is intended for 1500VDC-class systems and 300A current paths, but final suitability depends on load type, DC arc energy, precharge timing, cable sizing, busbar design, fuse coordination, and thermal rise.

The coil supply should be a stable 24VDC source. Designers should verify coil driver capacity, lead routing, auxiliary contact wiring, mounting orientation, terminal clearance, and enclosure spacing. If the system requires a higher current rating, HX21 or HX24 models may be more appropriate. If the system only requires 800VDC switching, a GV24 or GX family contactor may be enough.
