Used for sizing of switch gears for DOL starter

DOL Starter input fields are:

System Voltage (V)

Phase (1ph/3ph)

Type of Motor (single phase, 3-phase induction, synchronous, wound rotor etc.)

Motor Size (HP or kW)

Motor Code (A, B, C… -H)

Motor Efficiency (%)

Motor RPM

System P.F

Application of Motor (motor load in household application, hermetic refrigerant comperssor motor etc.)

According to above inputs, following starters components are calculated:

Motor Torque / Current

Fuse (As per NEC 430-52)

Circuit Breaker (As per NEC 430-52)

Over Load Relay Setting

Contactor (for DOL starter)

Type of Contactor
