MK 9163N.12/100 AC/DC 24V

The MK 9163N.12/100 AC/DC 24V is a DIN rail Thermistor Motor Protection Relay protects against thermal overload of motors caused by high switching frequency, heavy duty starting, phase failure on one phase, bad cooling, high ambient temperature. It functions as - If one of the sensors in the measuring circuit reaches the response temperature (or broken wire is detected), the device indicates failure. This failure is stored in the device with manual reset, even if the temperature goes back to normal. The unit can be reset by pressing the test/reset button, by bridging X1/X2 for a short moment or by disconnecting the auxiliary supply for a short time. Besides the reset function test/reset button provides in normal operation a test facility. The unit indicates fault as long as the button is activated.

• Over-temperature monitoring
• Broken wire detection in sensor circuit monitoring
• Short circuit detection in sensor circuit monitoring
• De-energized on trip
• LED-indicator for auxiliary supply and state of contact
• Output with 2 changeover contacts
