The thermistor motor protection relays CM-MSE, CM-MSS and CM-MSN are used to control motors equipped with PTC temperature sensors. The PTC temperature sensors are incorporated in the motor windings to measure the motor heating. This enables direct control and evaluation of various operating conditions. Depending on the products also ATEX approvals for use in hazardous areas are available.

How do you troubleshoot a thermal overload relay?
Ideally an overload relay should be set above maximum load by some small amount, but below the capability of the electrical circuits being protected. For example, breakers in your home are designed for overload protection; typical home wiring is 14 awg - 12 awg. If you have a 14 awg wire (good for 15A), you may install a 10A breaker, but if needed could install a 15A breaker depending on codes. A 20A breaker would not provide overload protection since it is too big. It would provide fault protection.
What is electrical motor type test?
test in lamp
Is swinburnes test direct or indirect test?
in this test their is a no load on dc shunt motor so it is an indirect test
What motor test will determine if someone is drunk?
It's called a 'sobriety test'
How do you test power transformer stability?
The stability and sensitivity test shall be performed for unit protection to prove the stability for through fault and sensitivity for the internal faults. The principle of the test is as followed. The protected zone of unit protection is restricted by location of the CTs. For stability test the primary current shall be injected through one set of two CTs such a way one of current inwards and other outwards. At relay terminal no operating current shall be observed for proper connection. Sensitivity test shall be conducted with same set-up with either reversed CT polarity or injecting primary current on only one CT of the set. At relay terminal, operating current shall be observed for proper function.
How to test a motor Thermal protection?
depend on to existence of test equepment. if we have a single phase injection current and we want test the thermal overload we have to do serie the heater and inject current two time of thier setting.
You suspect your radiator fan on a 1993 LeBaron is broken. How can you test it before you spend money on a new part?
Apply 12 volts directly to the fan motor. If it runs it is good. If so look at the thermal relay, as it may be bad.
1998 Grand Cherokee Larado fan not blowing Is this a relay or fan motor and how do I find and fix.?
Use a test light connected to the fan motor - if it lights fan motor is bad if it does not light could be fuse, relay, switch, or resistor
Cooling fans stop working on 2002 Chevy impala?
See if power is getting to fan motor--connect a test light and turn on A/C or defroster--if getting power to motor. Then motor is bad. If not getting power to fan-- Check fuse Check relay See if power is getting to fan motor--connect a test light and turn on A/C or defroster--if getting power to motor. Then motor is bad. If not getting power to fan-- Check fuse Check relay
Heater fan doesnt work in1995 dodge Dakota?
Check fuse. If good then check if you have power to motor (just need a 12 volt test light) If there is power then need fan motor-if no power check the relay. power to relay then you have found the problem. Relay is in the engine compartment on pass side of firewall. 95% of time the relay is out
How do you test electric fan 1988 Honda accord?
Apply 12 volts directly to the fan. If it runs, it is good, so proceed to checking the fuse and thermal relay.

How do you test the windshield motor on a 1991 Chevy S10?
You could try to use "jumper" wires from a 12volt battery if it doesnt move them the motor is bad. If it does then the relay\fuse or switch is bad. Hope this helps you.
How do I test a cooling fan motor on a 1992 Miata?
Apply 12V directly to the motor and see if it works Turn ignition switch and A/C on and check to see if you are getting power to the fan motor- if so motor is bad - if not could be a bad fuse or relay or sensor switch
How do you test vehicle relay switches?
The quickest & easiest way to test a relay is by substitution. It can be bench tested using wires and a test lamp.
What makes heater quite blowing on a 2003 pontic grand prix?
could be a fuse, a relay, the blower motor or the blower resistor. It's easy to check the fuse, using the owners manual. I am not sure where the relay is, and it requires special tools or replacement with a known good relay to test. If the blower works on high and no other speed, then the resistor is bad. If fuse and relay are good, and blower does not work in any position, suspect the blower motor itself.
How do you test the air conditioner relay on '97 Ford Ranger?
Swap the relay with another like relay.
