Danfoss MBC 5000 and MBC 5100 Heavy Duty Pressure Switch

Danfoss 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 Pressure Switch 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.
