Mechanical Power Relays MPR

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.
