EV-B Relays (DC Contactors)

The Panasonic EV-B Contactor Series offers a unique advantage with both vertical and horizontal mounting options, solving PCB height restriction challenges. This DC Contactor delivers exceptional performance with a minimum cut-off capacity of 2000A at 500V DC. It is this combination of flexibility and high-load reliability that sets the EV-B Series Automotive Relay (DC Contactor) apart as a design-friendly, yet powerful solution.

At just 360 grams, the EV-B Series Relay is lightweight and can maintain endurance under elevated temperatures. While maintaining stable operation with a switching life of 900A for 20 seconds at 85 °C, the EV-B Relay demonstrates resilience in demanding conditions. The ambient temperature rating of 60 °C at 15% duty ensures reliable operation in harsh environments. Combined with its compact weight, the EV-B Series is a durable and efficient choice for next-generation designs.
