Sensata Gigavac PNC113CDA

Sensata Gigavac PNC113CDA is a 30A 1500VDC normally closed High Voltage DC Contactor for capacitor discharge, dump switch, safety bleed, and fail-safe high voltage DC circuits. This PNC113 series High Voltage DC Contactor uses a 24VDC coil, SPST-NC contact form, stud terminals, chassis mounting, and hermetically sealed construction. Unlike a normally open main power contactor, PNC113CDA is a High Voltage DC Contactor designed for applications where the circuit should remain closed in the unpowered state and open only when the coil is energized.

This page is written around capacitor discharge and fail-safe dump switching, not general battery main disconnect service. In a high voltage DC power system, stored energy in capacitors can remain after the main contactor opens. A normally closed High Voltage DC Contactor such as PNC113CDA can support a discharge path or dump circuit strategy when the system design requires a default closed condition. For engineers working with 1500VDC-class equipment, this High Voltage DC Contactor provides a compact sealed option for controlled low-current discharge functions.

Product Positioning

PNC113CDA is positioned as a compact MiniTACTOR-style High Voltage DC Contactor for 30A normally closed switching. It is suitable for capacitor banks, inverter DC link discharge circuits, charger output bleed paths, PV test equipment, and safety-related dump circuits. The High Voltage DC Contactor is not intended to replace a large main power contactor; instead, it supports auxiliary switching roles where 30A current capacity and normally closed behavior are required.

The 24VDC coil makes PNC113CDA easy to integrate into industrial control cabinets, charger controllers, and energy storage service circuits. Many control systems already use 24V auxiliary power, so this High Voltage DC Contactor can be controlled without adding a separate 12V or 48V supply. The sealed construction also helps the High Voltage DC Contactor operate in cabinets exposed to dust, humidity, and thermal cycling.

Features and Benefits

The normally closed configuration is the most important feature of PNC113CDA. A normally closed High Voltage DC Contactor can support designs where a discharge or dump path should exist when the control coil is not powered. This behavior can be valuable in capacitor discharge circuits, test fixtures, and safety logic where the system needs a defined default state.

The 1500VDC capability makes this High Voltage DC Contactor useful in modern power electronics. PV inverters, battery chargers, laboratory supplies, and DC link assemblies may operate at voltages where ordinary low-voltage relays are not suitable. PNC113CDA gives designers a small High Voltage DC Contactor for controlled auxiliary switching instead of using an oversized main contactor for a low-current function.

The sealed design helps protect the contact system from contamination. In discharge or dump circuits, reliable contact behavior matters because the circuit may only operate during shutdown, service, or fault handling. A hermetically sealed High Voltage DC Contactor reduces exposure to dust and moisture and supports repeatable performance in demanding electrical cabinets.

Applications

• Capacitor discharge circuits requiring a normally closed High Voltage DC Contactor.
• Dump switch paths in high voltage DC power electronics.
• PV inverter DC link bleed and service discharge systems.
• Battery charger safety circuits using 24V control power.
• Laboratory high voltage DC test stands and validation fixtures.
• Auxiliary safety loops where a compact 30A High Voltage DC Contactor is preferred.
• Energy storage service circuits that require defined normally closed behavior.

Selection Guide

Select PNC113CDA when the design needs a normally closed High Voltage DC Contactor, 30A current capacity, 1500VDC-class capability, 24VDC coil control, and stud terminal connection. If the circuit requires normally open operation, select a P-series normally open MiniTACTOR instead. If the control supply is 12V or 48V, compare the correct PNC113 coil variant. If the current path is a main battery line rather than a discharge path, choose a higher-current High Voltage DC Contactor from the GV, GX, or HX families.

Before using PNC113CDA, confirm discharge resistor sizing, stored energy, maximum circuit voltage, coil driver capability, thermal rise, and fail-state requirements. A High Voltage DC Contactor in a discharge circuit should be selected together with the resistor, controller logic, insulation design, and service procedure.
