£257.86
The Lovato 31DRPT110 is a thermistor motor protection relay designed for monitoring motor temperature through compatible thermistor protection circuits. Operating from a 110 V AC, 50/60 Hz supply, it provides a dedicated motor protection solution for industrial machinery, control panels and motor starting systems.
Part of the Lovato DRPT thermistor protection relay range, the 31DRPT110 offers selectable manual or automatic reset and incorporates a test button for functional checking. The relay is designed for standard 35 mm DIN rail mounting, allowing straightforward installation within industrial electrical enclosures.
The 31DRPT110 has a 250 V rated insulation voltage between supply, inputs and outputs, together with a 4 kV rated impulse withstand voltage. Screw terminals, IP20 frontal protection and flexible installation orientation support practical integration into industrial motor protection systems.
Thermistor protection relays are used with temperature-sensitive motor protection circuits to monitor thermal conditions within motors and other electrical equipment. This provides temperature-based protection that can complement conventional current-based motor protection methods.
The Lovato 31DRPT110 combines thermistor protection functionality with manual or automatic resetting and a test button. Its 110 V AC supply and 35 mm DIN rail mounting make it suitable for integration into compatible industrial motor control and protection systems.
