AER6V-300Y-F 300A High Voltage Relay with extra Auxiliary Contact
DC High Current Relay
Product Overview
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.
Key Features
Why This Model Is Specified
- Contact points sealed by ceramic enclosure, and anti-arc by inert gases.
- Permanent magnetic extinguishing arc, high voltage DC cut off
- Anti-magnetic disturbances and explosion-proof
- RoHS listed
