Wyłącznik zabezpieczający przed wysokim ciśnieniem 2,9/2,3 MPa (zielony) – 7010530

Bosta – High Pressure Protection Switch 2.9/2.3 MPa (Green)

This genuine Bosta high pressure protection switch monitors refrigerant discharge pressure in pool heat pumps, cutting out at 2.9 MPa and automatically resetting at 2.3 MPa. It safeguards the compressor against dangerous over-pressure conditions, preventing costly damage to the refrigeration circuit. The green colour-coding allows for quick visual identification during servicing and installation.

Function & Protection

Installed on the high-pressure side of the refrigerant circuit, this switch interrupts the compressor circuit the moment discharge pressure reaches the 2.9 MPa cut-out threshold. Once pressure drops back to the 2.3 MPa reset point, normal operation can resume. This automatic protection helps prevent compressor burnout caused by refrigerant overcharge, blocked condenser airflow, or high ambient temperatures.

Dlaczego oryginalność ma znaczenie

Using an original Bosta replacement switch ensures that cut-out and reset pressures are factory-calibrated to precise tolerances, maintaining the safety and efficiency standards of your heat pump. Third-party substitutes may carry inaccurate trip points, potentially voiding warranty coverage or leaving the compressor unprotected at critical moments.

Instalacja

The switch is designed to be fitted by a qualified refrigeration or pool heating technician, as work on the refrigerant circuit requires F-gas certification in most European countries. Always isolate the unit from power and recover refrigerant pressure before replacing this component, and verify correct operation with a manifold gauge set after installation.
