CN-L Series Relays

Panasonic's CN-L Series is an automotive relay with an SPST (1FormA) contact arrangement with a maximum 150A at 14VDC continuous carry current capability and 2-coil latching functionality. This relay is mounted using screw terminals and can be used in automotive environments up to 125 DegC ambient temperature. The CN-L Series Relay is typically used for battery disconnection and protection of lithium batteries in automotive applications. With 2 separate coils, this relay can be easily controlled with dual power supply switching.

Features and Benefits

Continuous Carrying Current Possible at 150 A (at 85°C 185°F) or 80 A (at 125°C 257°F)
Maximum 1,500 A Conductivity
Can Be Used In Environments with 125°C 257°F Ambient Temperature

Applications

Main Relay Application For Protection Of Lithium Batteries, Etc.
Battery Disconnect Application
Dual Power Supply Switching Application
