Sensata Gigavac HX22CC

Sensata Gigavac HX22CC is a 300A 1500VDC High Voltage DC Contactor from the HX22 series, designed for remote microgrid power cabinets, isolated battery shelters, containerized DC systems, and unattended high-voltage power nodes. This High Voltage DC Contactor uses an SPST-NO-DM main contact form, a 24VDC coil, stud power terminals, flying lead control wiring, chassis mounting, no auxiliary contact, and hermetically sealed construction. It is a practical choice when a cabinet needs reliable 1500VDC-class switching but does not require built-in contact feedback.

HX22CC is best positioned for power systems that already monitor contactor behavior through bus voltage, current sensors, controller state, or remote telemetry. In remote microgrid equipment, reducing extra feedback wiring can simplify the harness and make field service easier. The 300A rating supports meaningful DC branch current, while the 1500VDC voltage class provides design margin for battery strings, DC-coupled renewable inputs, and power conversion links.

Product Positioning

HX22CC should be positioned as a no-auxiliary High Voltage DC Contactor for remote power cabinets and autonomous DC infrastructure. Unlike HX22CBB, HX22CC does not focus on normally open auxiliary feedback. Unlike HX22CCC, it should not be positioned around auxiliary diagnostic logic. Its value is simpler coil-driven isolation in systems where monitoring is handled by the cabinet controller or external instrumentation.

The 24VDC coil fits common industrial control supplies used in microgrid cabinets, telecom-style energy shelters, monitoring panels, and battery control boxes. Flying leads allow the contactor to be mounted near the high-voltage bus while the coil wiring routes to a low-voltage control compartment.

Features and Benefits

The 1500VDC rating makes HX22CC suitable for elevated-voltage DC systems where standard low-voltage relays cannot be used. This High Voltage DC Contactor can isolate battery strings, renewable DC branches, converter inputs, and protected high-voltage loads in compact cabinet layouts.

The no-auxiliary-contact configuration keeps wiring focused. In remote systems with voltage transducers, shunts, insulation monitoring, and controller telemetry, contactor state may be confirmed without a built-in auxiliary contact. HX22CC supports that simpler architecture while retaining sealed high-voltage switching performance.

The 24VDC coil matches common cabinet control power. Many off-grid power systems use 24VDC for controllers, communications modules, relays, fans, and safety circuits. Using the same control voltage for the High Voltage DC Contactor can reduce auxiliary power complexity.

Stud terminals provide secure high-current connection points for busbars or cables. Flying leads give the designer freedom to route the coil circuit through wire ducts, harnesses, or service loops. This is useful in containerized cabinets where power hardware and control electronics are separated.

Applications

HX22CC is suitable for remote microgrid power cabinets, isolated battery shelters, telecom energy systems, containerized renewable power units, and high-voltage DC branch isolation. In these systems, this High Voltage DC Contactor can disconnect a battery branch, isolate a converter input, switch a protected DC output, or open the power path during remote shutdown.

It can also be used in charger support modules, industrial DC cabinets, test shelters, and off-grid storage equipment where 300A current capacity and 1500VDC switching are required. The no-auxiliary version is best when external sensing already provides the needed operating confirmation.

Selection Guide

Before selecting HX22CC, confirm maximum DC voltage, continuous current, peak current, inrush current, switching frequency, and load type. Battery strings, converter inputs, and long cable runs may require precharge, surge protection, or additional fault-current coordination. This High Voltage DC Contactor should be evaluated with the complete protection design.

Use HX22CC when the system has a 24VDC coil supply and does not need built-in auxiliary feedback. If the controller requires contact feedback, HX22CBB, HX22CCB, HX22CAB, or HX22CCC variants may be reviewed depending on the required auxiliary contact configuration.

FAQ

What is HX22CC used for?

HX22CC is used for remote microgrid cabinets, battery shelters, containerized DC systems, converter inputs, and 1500VDC branch isolation.

Is HX22CC a High Voltage DC Contactor?

Yes. HX22CC is an HX22 series High Voltage DC Contactor rated for 300A and 1500VDC-class switching.

What coil voltage does HX22CC use?

HX22CC uses a 24VDC coil. DigiKey lists 16VDC must-operate voltage and 0.5VDC must-release voltage.

Does HX22CC include auxiliary contacts?

No. Public distributor data for HX22CC does not list auxiliary contacts, so it should be treated as the no-auxiliary configuration.

How is HX22CC different from HX22CBB?

HX22CC is the simpler no-auxiliary version, while HX22CBB is listed with normally open auxiliary feedback. Both are HX22 300A 1500VDC contactors with 24VDC coils.

Conclusion

HX22CC is a 300A 1500VDC High Voltage DC Contactor for remote microgrid cabinets, isolated battery shelters, containerized DC systems, and off-grid power infrastructure. With its Sensata Gigavac HX22 sealed construction, 24VDC coil, stud terminals, flying leads, chassis mounting, and no-auxiliary-contact configuration, it provides a straightforward switching option for systems that rely on external sensing and controller telemetry for status confirmation.
