Danfoss Electronics MBC 5000, MBC 5100 Data Sheet

Data sheet

Heavy duty pressure switch
MBC 5000 and MBC 5100

MBC pressure switches are used in industrial and
marine applications where space and reliability
are the most important features.

MBCs are compact pressure switches, designed
according to our block design to survive in the
harsh conditions known from machine rooms
onboard ships.

MBCs have high vibration resistance and
MBC 5100 features all common marine approvals.
The fixed, but low differential guarantees
accurate monitoring of critical pressures.

MBV test valves can be delivered as standard
option for MBC.
