EV-A Series Relays (DC Contactors)

Panasonic’s EV-A Series Automotive Relay (DC Contactor) is a 250A @ 500V DC Contactor that has an incredibly small and lightweight design. The EV-A Series can withstand up to an 8,000A short circuit current rating and has a high cut-off capability of 1,800A @ 500VDC without requiring any contact polarity. This Automotive Relay is suitable for usage in Electric Vehicles, DC Charging Stations and other high voltage DC applications such as Hybrid Construction Equipment.

Features and Benefits:

Slim Size: 42.5 mm (W) x 56.5 mm(L) x 63.0 mm(H)
Lightweight Design: Weighs Approximately 400 grams
Robust Design for Dealing with High Current Surge: Can Withstand Up To 8,000A SCCR (Short Current Circuit Rating) at 5ms Maximum Capacity with No Smoke or Ignition
High Current Breaking Capability: Can Support Up to 1,800A @ 500 V.DC Cut-Off for at Least 1 Operation at L/R ≦ 1 ms Without Polarity
Does Not Require Polarized Load Connection: The Output Load at the Contacts Can Be Connected Without Polarization Allowing for a High Freedom Of Design and No Risk of Reversing the Connection
RoHS/REACH Compliant
