They are suitable for light/standard duty applications. Trip class corresponding to minimum overload current withstand time. For example: Class 10A = overload ratio 8 (8 times nominal current) for 1.6 seconds; Class 10 = overload ratio 8 for 3 seconds.
Where can I find some technical information about your products?
Please see our online product catalogue: http://www.danfoss.com/BusinessAreas/IndustrialAutomation/Product+catalogue/IA+product+catalogue.htm
Does a thermal overload relay provide full protection of the motor?
A thermal overload relay equipped with bimetals is a relatively small, yet reliable appliance to protect electrical motors against: –mechanical overload, –asymmetrical operation, –phase failure. To provide protection against short circuit current you should use fuses. For full protection of the motor, we recommend CTI circuit breakers.
