Littelfuse Contactor Relay, Bolt Mounting, Copper Alloy Contact, Nylon Housing, 250 A, IP67, 40 to 85 °C

The DCNHE250 series contactor is designed for electric vehicle and energy storage systems requiring reliable switching of high-voltage DC power. It supports continuous current up to 250 A and a maximum of 1000 V, making it suitable for applications such as battery power supply, DC power control, charging systems and other electronic control circuits. A sealed, compact structure with a corrosion-resistant resin housing provides protection in harsh environments. The attached coil economizer uses Pulse width modulation (PWM) to reduce power consumption and heat generation after the contactor is energized. The contactor is offered with either polarized or non-polarized load terminals. All models feature polarized coil terminals with voltage options of 12 to 36 V or 32 to 95 V. Auxiliary contact options include SPST-NO and SPST-NC for added control flexibility. This model (DCNHE250QFA-B) of the DCNHE250 series contactor features polarized contacts, a 12 to 36 VDC coil rating, SPST-NO auxiliary contact and stud terminal power connection.Contactor Relay, Bolt Mounting, Copper Alloy Contact, Nylon Housing, 250 A, IP67, 40 to 85 °C, Standards: U RoHS and REACH Compliant, 1000 VDC, For Battery Electric Vehicles, Hybrid Electric Vehicles, Material Handling, Electric Maintenance and Transport Vehicles, Industrial Applications
