High pressure switch 25 bar with cable L=2900mm – code: M74085 – Climma

High pressure switch 25 bar with cable L=2900 mm (Climma) – M74085

The high pressure switch 25 bar with cable L=2900 mm (code M74085) branded Climma is a component used in air conditioning and refrigeration systems, particularly in the nautical field, for the monitoring of pressure on the high side of the refrigeration circuit. It is a device used as a control and safety element: it detects pressure and, upon reaching the set value, can act on the electrical circuit according to the system configuration.

This version integrates an electric cable of 2900 mm, designed to facilitate connection to the electronic board or control system, reducing the need for adaptations or extensions during replacement.

Main features and details

The M74085 pressure switch is designed to operate as a high pressure switch within the refrigeration circuit. Its function is to control the pressure on the high side and provide a command action (opening/closing of the electrical circuit) when the set threshold is reached.

Control function on the high pressure side

In HVAC and refrigeration systems, the high pressure switch is a fundamental component for managing operating conditions. In the presence of overpressure, the device can:

• interrupt the operation of the compressor or
• send a signal to the control unit, depending on the logic and configuration of the system.

In this way, it helps protect the refrigeration circuit and its components, supporting the maintenance of operating conditions consistent with the system design.

Calibration and spare identification

• Set value: 25 bar
• Product code: M74085
• Type: high pressure switch

The reference M74085 allows unique identification of the spare part, useful both when ordering and during scheduled or corrective maintenance.

Integrated cable for connection

The model is equipped with integrated electrical cable 2900 mm long. This feature is particularly useful when the pressure switch is installed in positions not immediately close to the control unit or connection point, typical of some onboard fittings or technical compartments.

The integrated cable can simplify installation because it allows a more direct connection, limiting additional wiring interventions.

Typical applications

As original replacement Climma, The M74085 pressure switch is used in air conditioning and refrigeration systems (particularly nautical) where pressure control on the high side is required. It is suitable for maintenance and functional restoration interventions when the installed pressure switch is faulty, unreliable, or no longer meets the system's requirements.

Recurring uses in maintenance

• Monitoring of the high pressure of the refrigeration circuit.
• Protection of the compressor and other components under overpressure conditions.
• Consent/block management of operation towards the electronic control unit.
• Replacement of the original pressure switch to restore the correct functioning of the system.

Advantages for the installer and for the system

In a technical context such as onboard air conditioning and refrigeration, choosing a correctly identified pressure switch with wiring suitable for the application helps make the intervention more straightforward and reduces uncertainties during replacement.

Why choose this spare part

• Identifiable spare part by code M74085, useful for orderly spare parts management.
• Declared calibration at 25 bar, consistent with use as a high-pressure pressure switch.
• Integrated cable of 2900 mm for a more practical connection to the board or control system.
• Use in Climma systems in the nautical field, where protection of the refrigeration circuit is an essential aspect of maintenance.

Usage and operational notes

The high-pressure pressure switch is a component that interacts with both the refrigeration circuit and the electrical control/command circuit. For this reason, replacement and verification of correct operation should be performed by qualified personnel, following the procedures provided by the system and good maintenance practices.

Practical indications during replacement

• Check the (5110407) with the requested replacement; M74085 with the spare part to be replaced.
• Consider the presence of the integrated 2900 mm cable in cable routing management and connection to the control unit.
• After installation, perform the functional checks provided by the system to confirm the correct reading/intervention of the pressure switch.

If you are working on an existing system and have doubts about the electrical configuration (opening/closing logic of the contact or control unit management), it is advisable to refer to the system diagram or the technical documentation of the control system.
