Description

The mechanical power relays are a product group of electro-mechan- ical high current relays. These relays have been designed for the use in utility vehicles and passenger cars and are able to switch or carry up to 300 A continuous load at 12 or 24 V DC. The high number of operating cycles at rated load, including capacitive and inductive loads, make these power relays particularly suitable for the utility vehicle sector. The main terminals are stud terminals. Screw flanges allow horizontal and vertical mounting. Thus these relays can replace any conventional power relays in the market. Versions
