Sensata Gigavac PNC113FDA DC Contactor

The Sensata Gigavac PNC113FDA is a sealed normally closed DC contactor from the PNC113 MiniTACTOR Series, designed for HVDC discharge and dump switch applications that require a compact SPST-NC contactor. It provides a 30A contact rating, 1500VDC nominal switching voltage, 48VDC coil operation, and stud termination. This model is suitable for capacitor discharge circuits, high-voltage battery systems, energy storage equipment, solar power systems, DC bus discharge modules, industrial power electronics, and safety discharge applications. In this model, 1500VDC refers to the main contact switching voltage, while 48VDC refers to the coil voltage used to operate the contactor.

Product Description

The Sensata Gigavac PNC113FDA DC contactor is a compact normally closed MiniTACTOR designed for high-voltage DC discharge and dump switching circuits. Unlike standard normally open contactors, the PNC113FDA contact path is closed when the coil is not energized and opens when the 48VDC coil is energized. This makes it useful in systems where a discharge path must be available by default, such as capacitor discharge, DC bus bleed-down, and safety dump circuits.

The PNC113FDA uses an SPST-NC contact arrangement, also described as 1 Form Y. The main contact rating is 30A, and the nominal switching voltage is 1500VDC. The 1500VDC value belongs to the main power switching path, while the 48VDC value belongs only to the coil circuit. This separation allows a control system to manage a high-voltage DC discharge path through a lower-voltage coil signal.

A key advantage of the Sensata Gigavac PNC113FDA is its hermetically sealed contact chamber. The sealed design helps protect the contact system from dust, moisture, oxidation, and contaminated environments. This is important for energy storage systems, solar equipment, high-voltage battery packs, industrial power electronics, and outdoor DC control boxes where environmental exposure can reduce the reliability of ordinary open-frame relays.

The PNC113 MiniTACTOR platform is built as a small, lightweight, and cost-effective solution for HVDC discharge applications. It is not position sensitive and can be mounted in any orientation, which gives engineers more flexibility when designing compact power modules or discharge assemblies. The PNC113FDA uses M4 power studs and M3 coil studs, supporting secure connections in panel-mounted and chassis-mounted systems.

Applications

The PNC113FDA DC contactor is commonly used in systems that require a normally closed high-voltage discharge path. Typical applications include capacitor discharge circuits, DC bus discharge modules, battery energy storage systems, solar photovoltaic equipment, inverter systems, high-voltage test equipment, industrial power conversion, and EV auxiliary safety circuits.

In a battery or power electronics system, the Sensata Gigavac PNC113FDA can be used as a dump switch, discharge contactor, bleed-down contactor, or safety discharge device depending on the circuit design. Because it is normally closed, it should be selected when the system requires the contact path to remain closed without coil power. For main battery switching or load disconnect positions that require a normally open contactor, a different P Series, GV Series, or GX Series model may be more suitable.

Why Choose Sensata Gigavac PNC113FDA

The Sensata Gigavac PNC113FDA is a practical choice when the design requires a compact 30A normally closed DC contactor with 1500VDC switching capability and 48VDC coil operation. Compared with normally open contactors, this model is better suited for default-closed discharge circuits. Compared with open-frame relays, the hermetically sealed construction provides better protection in demanding DC environments.

For replacement and maintenance projects, PNC113FDA should be selected when the original system requires PNC113 Series performance with SPST-NC contact form, 30A current rating, 1500VDC nominal switching voltage, 48VDC coil voltage, M4 power studs, and M3 coil studs. Before ordering, confirm the contact logic, coil voltage, switching voltage, discharge current, mounting space, and terminal requirements.
