AER6V-300Y-F 300A High Voltage Relay with extra Auxiliary Contact

Application:

High current and high voltage DC contactor relays for electric vehicle applications such as battery power supply, DC power control, circuit protection, and other switch controls. Can also be used in uninterruptible power supply and other electronic control systems. Are available with polarized and non-polarized contacts to best suit electrical systems’ polarity. Coil Economizer greatly reduces coil power and heating after the contactor is energized. Once the contactor is energized, it takes minimal coil power to keep the contacts closed due to Pulse Width Modulation (PWM) reducing the average power delivered by pulsing the electrical signal.

Rated Current: 300A

Max Load Voltage: 750VDC

Coil Voltage: 12VDC/24VDC

Auxiliary Contact: 1NO 2A/30VDC, 3A/125VAC

Main Contact: 1NO

Electrical Life (MAX): 1000 times
