Mechanical Power Relays MPR
Description
The mechanical power relays are a product group of electro-mechanical 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.
