Sensata Gigavac HX460CAA DC Contactor

The Sensata Gigavac HX460CAA is a sealed high-voltage DC contactor from the HX460 Series, designed for robust high-power load break switching in systems up to 1500VDC. It provides a 1000A contact rating, 24VDC coil operation, chassis mounting, stud and wire lead termination, 38 cm / 15 in flying leads, and mechanically linked SPDT auxiliary contacts. This model is suitable for photovoltaic inverters, battery inverters, battery packs, DC combiner boxes, energy storage systems, industrial drives, and other HVDC power conversion equipment. In this model, 1500VDC refers to the main contact switching voltage, while 24VDC refers to the coil voltage used to operate the contactor.

Product Description

The Sensata Gigavac HX460CAA DC contactor is designed for high-voltage and high-power DC switching where reliable load break capability is required. As part of the HX460 Series, this model combines a 1000A contact current rating with 1500VDC switching capability, making it suitable for photovoltaic systems, battery energy storage, battery inverters, DC combiner boxes, industrial drives, and other demanding HVDC power conversion equipment.

The HX460CAA uses an SPST-NO main contact arrangement, also described as 1 Form X. The main contact remains open when the coil is not energized and closes when the 24VDC coil receives the correct control voltage. This allows a low-voltage control circuit to manage a very high-power DC load path. The 1500VDC value belongs to the main switching circuit, while the 24VDC value belongs only to the coil control circuit.

A key feature of the Sensata Gigavac HX460CAA is its mechanically linked SPDT auxiliary contact. This auxiliary contact is designed to provide reliable indication of the main contacts in the closed position, which is important for critical safety applications. Compared with contactors that have no auxiliary feedback, the HX460CAA gives the control system an additional status signal for diagnostics, interlock logic, and safe system sequencing.

The HX460 Series is built for robust high-voltage and high-power load break duty. Sensata describes this series as a bi-directional DC contactor designed for high-voltage power conversion equipment. The contactor also provides strong isolation performance, including 10kV withstand between open contacts, which supports safety-critical applications where high-voltage separation is important.

The HX460CAA uses hermetically sealed construction to protect the internal contact system from dust, humidity, oxidation, and contamination. This makes it suitable for outdoor power conversion equipment, renewable energy systems, battery packs, and industrial DC cabinets where environmental exposure can reduce the service life of ordinary open-frame contactors.

Applications

The HX460CAA DC contactor is suitable for high-voltage systems that need dependable connection and disconnection of battery, inverter, load, or DC bus circuits. Typical applications include photovoltaic inverters, battery inverters, battery energy storage systems, DC combiner boxes, industrial drives, high-voltage power conversion cabinets, DC charging equipment, and large battery disconnect systems.

In a power conversion system, the Sensata Gigavac HX460CAA can be used as a main DC contactor, inverter input contactor, battery disconnect contactor, charge path contactor, or safety isolation device depending on the electrical design. Its 1000A current rating and 1500VDC switching capability make it suitable for high-power platforms where sealed construction, auxiliary feedback, and strong isolation performance are required.

Why Choose Sensata Gigavac HX460CAA

The Sensata Gigavac HX460CAA is a strong option when the system requires 1000A current capacity, 1500VDC switching voltage, 24VDC coil operation, sealed construction, 15 in flying leads, and mechanically linked SPDT auxiliary contacts. Compared with lower-voltage or lower-current contactors, this model is better matched to high-power HVDC systems. Compared with contactors without auxiliary feedback, the HX460CAA supports safer monitoring and interlock design.

For replacement and maintenance projects, HX460CAA should be selected when the original system requires HX460 Series performance with 1000A contact rating, 1500VDC nominal switching voltage, 24VDC coil voltage, 38 cm / 15 in flying leads, and SPDT auxiliary contacts. Before ordering, confirm coil voltage, auxiliary contact wiring, load current, switching voltage, mounting space, and terminal requirements.
