Sensata Gigavac HX241CCB

Sensata Gigavac HX241CCB is a 400A 1500VDC High Voltage DC Contactor from the HX24 series, built for high-current DC charging cabinets, battery energy storage output sections, and industrial DC distribution panels. This High Voltage DC Contactor uses a 24VDC coil, SPST-NO main contact arrangement, auxiliary contacts, chassis mounting, stud terminals, wire leads, and hermetically sealed construction. For system designers who need a High Voltage DC Contactor with higher current capacity than compact 350A devices, HX241CCB provides a practical 400A switching component for 1500VDC-class power systems.

The page angle for HX241CCB is charger-output and cabinet-distribution service. A DC fast charging cabinet or high-current power conversion cabinet needs a High Voltage DC Contactor that can isolate the output path, support monitoring through auxiliary contacts, and work with a 24V control supply. HX241CCB is not only a current-rated switch; it is a controlled High Voltage DC Contactor for equipment where the controller must coordinate precharge, main contact closure, output enable, and fault shutdown.

Product Positioning

HX241CCB is positioned as a 400A High Voltage DC Contactor for 1500VDC equipment that uses 24VDC control logic. The HX24 series provides a stronger current class than many compact contactors while remaining suitable for cabinet installation. In charging infrastructure, a High Voltage DC Contactor such as HX241CCB can be placed in the charger output stage, battery interface section, or main DC distribution rail, depending on the final electrical architecture.

For OEM projects, HX241CCB is a suitable High Voltage DC Contactor when the design calls for a sealed 400A path and contact-state feedback. The auxiliary contacts allow the charger controller or power cabinet PLC to confirm the position of the High Voltage DC Contactor before enabling power flow. This is important in EV charging, battery charging, DC bus distribution, and service disconnect arrangements where feedback supports safer sequencing.

Features and Benefits

The 400A rating makes HX241CCB a useful High Voltage DC Contactor for charger output circuits and high-current DC distribution rails. In a charging cabinet, current capacity must be matched to the cable, busbar, fuse, sensor, and power module design. A High Voltage DC Contactor in this position must carry operating current while opening or closing under the control sequence defined by the system.

The 24VDC coil is another integration benefit. Many EV charging cabinets, industrial DC panels, and energy storage controls use 24V power supplies for relays, PLC inputs, fans, sensors, and safety modules. HX241CCB allows the High Voltage DC Contactor to be driven from that same control layer when the coil supply and protection design are properly matched. Built-in coil suppression in the HX24 platform also reduces the need for extra suppression components in many control layouts.

The hermetically sealed design helps the High Voltage DC Contactor operate in equipment that may face humidity, dust, temperature changes, and installation-site contamination. Auxiliary contacts support verification of the switching state. This is important because a charger or DC cabinet controller should confirm the High Voltage DC Contactor position before declaring the output ready or before allowing service access.

Applications

• DC fast charging output cabinets requiring a 400A High Voltage DC Contactor.
• Battery charger cabinets using 1500VDC-class DC buses and 24V control power.
• Energy storage converter output stages that require auxiliary contact feedback.
• Industrial DC distribution panels for high-current isolation and sequencing.
• Battery test stands where a repeatable High Voltage DC Contactor is needed for controlled output connection.
• Renewable energy DC collection cabinets with 400A switching requirements.
• Service disconnect and safety interlock circuits in high voltage DC equipment.

Selection Guide

Select HX241CCB when the system needs a 400A High Voltage DC Contactor, a 1500VDC nominal switching class, 24VDC coil control, auxiliary contact feedback, and stud-terminal power wiring. If the equipment only requires 350A, an HX21 series High Voltage DC Contactor may reduce size. If the design requires a 12V or 48V coil, confirm the suffix and coil code before purchase. If the circuit is intended for charger output, verify precharge, fuse coordination, short-circuit protection, busbar spacing, and controller feedback inputs.

HX241CCB should be selected as part of a complete DC power control design. A High Voltage DC Contactor does not replace system-level protection, insulation monitoring, proper cable sizing, or arc management. It works with those elements to provide controlled connection and disconnection. For charging cabinets and DC distribution equipment, the value of HX241CCB is the combination of 400A current rating, 24V control, sealed construction, and auxiliary feedback.

FAQ

Is HX241CCB suitable for EV charging cabinets?

Yes. HX241CCB is a 400A 1500VDC High Voltage DC Contactor with a 24VDC coil, making it suitable for many charger-output and DC cabinet control architectures when applied within the full system design.

How is HX241CCB different from HX21CAB?

HX241CCB is an HX24 series High Voltage DC Contactor rated at 400A, while HX21CAB is a compact HX21 series device rated at 350A. Choose based on current requirement, space, and system coordination.

Why does auxiliary feedback matter in a charger cabinet?

Auxiliary contacts help the controller confirm whether the High Voltage DC Contactor is open or closed. This feedback can support output enable logic, fault response, service lockout, and sequence checks.

Does HX241CCB use a 24V coil?

Yes. HX241CCB is listed with a 24VDC coil, which fits many industrial controls and charging systems that already use 24V auxiliary power.
