Description
The ALQ EVQ100 Series 1500V 100A DC Contactor is a high-voltage switching solution designed for demanding electric vehicle, energy storage, and high-voltage DC power applications. The EVQ2H-100A model supports a rated operational voltage of 1500V DC and a continuous current rating of 100A at 23°C.
The contactor uses a 24V DC control coil and is designed for high-voltage battery and power-management systems where reliable isolation and switching of DC power circuits are required. The EVQ100 series is particularly suitable for DC fast charging equipment, energy storage systems, power battery systems, and high-voltage inverters.
Its epoxy-sealed construction and nitrogen-protected contacts help prevent oxidation while supporting effective arc cooling during high-voltage DC switching. The sealed design provides IP67 and IP69K protection, making the contactor suitable for demanding environments with exposure to dust, water, vibration, and temperature extremes.
The EVQ2H-100A DC contactor is designed for flexible installation and can be mounted in different orientations depending on the selected mounting configuration. It operates across an ambient temperature range of -40°C to +85°C and provides a specified mechanical life of 200,000 cycles.
