Time Current Characteristic MPW25 Class 10

The tripping characteristic shows the manual motor protector trip time in relation to the rated current.
The curves show average tolerance range values for an ambient temperature of 20ºC (68ºF), starting in cold state. Thermal trip
time when working in operating temperature is reduced to around 25% of the presented values. Under normal operating
conditions, all 3 manual motor protector phases must be conducting.
