Choose fuse type and capacity, according to the protection of the load characteristics, the electric motors size of the short circuit current working conditions and use of the occasion. Most of the small and diesel engine medium-sized motor with light load or full pressure relief starting, lamination starting current is usually 5 to 7 times of the rated current; The power capacity is larger, low-voltage distribution main transformer (including capacity) in 1000 ~ 400 electric water pump kva, system impedance is small, when water pump price short-circuit fault occurs, the short circuit current is larger; The workplace such as kiln, grinding, poor ventilation condition, the working environment temperature is higher.

Therefore, choose fuse breaking capacity and rated current of the melt, compared with the general industrial use should appropriately increase a bit. 3.1 the melt the experience formula of the rated current melt Electric motor rated current (A) = motor rated current (A) (3). 3.2 melt rated current simplified formula: "melt protection, kw by 6" the simplified formula, is refers to a 380 v cage motors, light load starting or decompression starting full pressure, low operating frequency, suitable for below 90 kw and cage motor. If the actual use of the motor starting frequently, or starting time is long, the empirical formula or water pump price the simplified formula of the above results can be appropriately increased a little, but it should not be too large. In short to achieve when the motor starting, melt by fusing; In the case of short circuit fault, the melt acmotor2.blogspot.com must be reliable fuse, squirrel cage induction motor cut off power supply, to achieve the purpose of the short circuit protection.
