Product Description:

Siemens Sirius 3RN1010-1CB00 motor protection device:

The motor protection device Siemens Sirius 3RN1010-1CB00 is shown here. Despite being worn, this item is in generally good shape with few to no cosmetic flaws. Thermistor Motor Protection Relay Dimensions W x H x D: 22.5 x 92 x 91 mm Operating temperature: -25…+60 °C Operating value of PTC thermistor: 3.4…3.8 kOhm Rated output: AC-15: 3 A @ 240 VAC, DC-13: 2 A @ 24 VDC Reset value of PTC thermistor: 1.5…1.65 kOhm Assembly type: DIN-Rail Output contact: 1 Break Contact (NC) Protection rating: IP20 Cold resistance max.: 1.5 kOhm Operating voltage: 24 VAC/DC

3RN1010-1CB00 specifications:

• Temperature-dependent resistors (PTC), which are inserted directly in the motor winding and abruptly change resistance at their limit temperature, are included in the motors for this reason.
• Monitoring of temperature with PTC sensors
• Display of wire break and short-circuit in sensor circuit
• Automatic reset
• 2 LEDs for ready and tripped
• 2 potential-free signal contacts: 1 normally open and 1 normally closed
• DIN rail mounting
• Operating value of PTC 3.4 to 3.8 kOhm
• Reset value of PTC 1.5 to 1.65 kOhm

Advantages:

Even in the most challenging ambient conditions, direct motor protection through temperature monitoring of the motor winding delivers 100% motor protection without the need for device changes. Additionally, versions with strong gold-plated contacts guarantee a high switching reliability that is even greater than an electronic control.
