EB-N Series Relays

Panasonic's EB-N Series is a sealed Automotive Relay with a low profile (23mm height) and screw mount with copper tab terminals. The low profile allows the EB-N Series Relay to be mounted within battery cells so it can function as the battery disconnection protecting the Lithium-ion batteries during a malfunction. 

The EB-N Series Relay has a polarized double-make SPST (1FormA) contact arrangement capable of 100A @ 60VDC continuous current at 85 Degrees Celsius ambient temperature and can carry 300A for 5 seconds. The EB-N Relay can also cut-off 1,500A at 60VDC for 1 operation has a high switching capacity of 35A @ 14VDC for the Normally Open contact and 20A @ 14VDC for the Normally Closed contact.

Both sealed and flux-resistant construction types are available. A built-in resistor option is available for coil protection against EMF. Both 12V and 24V DC coils are available in this series.
