£257.86
The Lovato 31DRPT24 is a thermistor protection relay designed for temperature-based protection of motors and compatible electrical equipment. Operating from a 24 V AC, 50/60 Hz supply, it provides a dedicated protection solution for industrial motor control and automation systems.
Part of the Lovato DRPT thermistor protection relay range, the 31DRPT24 supports selectable manual or automatic reset and incorporates a test button for functional checking. Two changeover auxiliary contacts provide control and signalling capability for integration into motor protection circuits.
The relay is designed for standard 35 mm DIN rail mounting and provides IP20 frontal protection. It has a 250 V rated insulation voltage between the supply, inputs and outputs together with a 4 kV rated impulse withstand voltage.
Thermistor protection relays are used with temperature-sensitive motor protection circuits to monitor thermal conditions within motors and other electrical equipment. When the thermistor circuit detects an excessive temperature condition, the protection relay can change the state of its output contacts so the associated control system can respond.
The Lovato 31DRPT24 combines thermistor protection with manual or automatic resetting, a test function and two changeover auxiliary contacts. Its 24 V AC supply and standard 35 mm DIN rail mounting make it suitable for integration into compatible industrial motor control and protection systems.
