The EN2, EP2, EPI and MR301 series power relays can meet the requirements of high quality and reliability in automotive
The EN2 and EP2 series are the twin relays which have two units in one package and smaller than conventional two relays.
The EN2 series is suitable for heavy load applications (35 A max.). The EP2 series is designed for medium load applications
Many of these relays have been used in automotive electronics applications throughout the world.
Twin relay for motor and solenoid reversible control
30% Iess relay space than conventional two relays
Contact switching current of 35 A max.
High performance and productivity by unique
symmetrical structure
Flux tight housing
Delivered in stick-tube for automatic insertion machine
Washable type available
