Protection Relay

TEMPERATURE
Two Adjustable Thermostat Switches with changeover contact for over temperature detection. Both the primary and secondary temperature thresholds are factory set at customer requirements within a 30°C to 120°C range.
One Thermometer with maximum temperature indicator provides visual temperature information.
PRESSURE
One Adjustable Pressure Switch with changeover contact. The tripping overpressure threshold of the pressure switch is factory set at customer requirement within a 100 mbar to 500 mbar.
DIELECTRIC LEVEL
A Reed Magnetic Switch with changeover contact is triggered when a dielectric-level decrease of over 170cm³ is achieved.
An integrated magnetic protection shields the Reed Switch from any external magnetic field interference.
PRESENCE OF GAS
Gassing or dielectric-level decrease is initially visible through the lowering of a small float.
This is followed by the lowering of the main float, visible all-round at 360°, which triggers the Reed Switch.
