This method has easy way of controlling the device. If the push button is pressed, the contactor gets energised and gets closed. MK 1 DOL STARTER ARE IN DIFFERENT HP / RELAY RANGE. RELAY RANGES : 1A / 1.6A/ 2.5A/ 4A/ 6.5A/ 10A/ 14A. A 3 phase induction motor derives its name from the fact that the rotor current is induced by the magnetic field, instead of electrical connections. The operating principle of a 3 phase induction motor is based on the production of a rotating magnetic field (r.m.f.). Motor Full Load Current (Line) = (5×0.746)x1000/1.732×415 = 6 Amp. Motor Starting Current = 6 to 7xFull Load Current A DOL starter (also known as a direct on line starter or across the line starter) is a method of starting a 3 phase induction motor. In a DOL Starter, an induction motor is connected directly across its 3-phase supply, and the DOL starter applies the full line voltage to the motor terminals To properly size a NEMA-style full-voltage, across-the-line motor starter, the only information required is the motor horsepower and voltage. Sizing an IEC starter of the same type requires knowing the motor load, the duty cycle and full load current. NEMA standards list 10 sizes to cover 2-hp to 900-hp motors. Although typical control relays operate in the 5 ms to 20 ms range, relays with switching speeds as fast as 100 μs are available. Reed relays which are actuated by low currents and switch fast are suitable for controlling small currents.
