Digital Electronic Overload Relay Motor Protector Thermal Overload Relay Samwha-Dsp SOPR-3DE-120 Digital

General SOPR-3DE series digital overload and lost phase relays are designed toprevent failures originated from motor heat. Setting D-Time: Set two to three seconds longer than the engine start time. O-Time: overcurrent operation time. Set less than motor endurance time with overcurrent. LOAD: Set more than 110% of motor starting current or less than 120% of motor running current. Relay status When energized: 95(COM) and 96(NC) is open circuit, 95(COM) and 98(NO) is short circuit. When triggered: 95(COM) and 96(NC) is short circuit, 95(COM) and 98(NO) is open circuit.
