Derating at higher temperature By derating the current to 80% of nominal current, the MSF can be operated at an ambient temperature of up to 50 C. E.g. a MSF-045 can operate a heavy load of 36 A (45 A*0.8). Environmental conditions Normal operation Temperature Relative humidity Max altitude without derating Storage Temperature Relative humidity Standards Market Low voltage switch gear and control gear - Part 1: General rules. Low voltage switch gear and control gear - Part 4-2: Contactors and motor starters AC semiconductor motor controllers and starters Russian certificate of conformity...

Semi-conductor fuses Always use standard commercial fuses to protect the wiring and prevent short circuiting. To protect the thyristors against short-circuit currents, superfast semiconductor fuses can be used if preferred (e.g. Bussmann type FWP or similar, see table below). FWP/FWJ Bussmann fuse Type
