This electrical calculator " Calculate Size Of DOL and Star-Delta Starter Components." can be downloaded free from below link.

This electrical calculation tool "Calculate Size Of DOL and Star-Delta Starter Components" is helpful for professional and engineers. This electrical tool 'Calculate Size Of DOL and Star-Delta Starter Components' is Easy way to calculate motor torque, fuse, CB, OL relay and contactor. For both DOL and Star-Delta Starter input fields are:

1. System Voltage (V)
2. Phase (1ph/3ph)
3. Type of Motor (single phase, 3-phase induction, synchronous, wound rotor etc.)
4. Motor Size (HP or kW)
5. Motor Code (A, B, C… -H)
6. Motor Efficiency (%)
7. Motor RPM
8. System P.F 
9. Application of Motor (motor load in household application, hermetic refrigerant compressor motor etc.)

According to above inputs, following starters components are calculated:

Motor Torque / Current

1. Motor Rated Torque (Full Load)
2. Motor Rated Torque (Full Load)
3. Motor Starting Torque
4. Lock Rotor Current IL (Min)
5. Lock Rotor Current IL (Max)
6. Motor Starting Current
7. Motor Full Load Current (Line)
8. Motor Full Load Current (Phase)

Fuse (As per NEC 430-52)

1. Non-Time Delay Fuse (Max)
2. Time Delay Fuse (Max)

Circuit Breaker (As per NEC 430-52)

1. Instantaneous Trip Circuit Breaker (Max)
2. Inverse Time Circuit Breaker (Max)

Over Load Relay Setting

1. Relay Min (70% of FLC Phase)
2. Relay Max (120% of FLC Phase) or
3. Relay Setting (100% of FLC Line)

Contactor (for DOL starter)

1. Type of Contactor
2. Making / Breaking Capacity of Contactor:
3. Main Contactor (100% of FLC Line):

Contactor (for Star-Delta Starter)

1. Type of Contactor
2. Making / Breaking Capacity of Contactor
3. Main Contactor (58% of FLC Line)
4. Delta Contactor (58% of FLC Line)
5. Star Contactor (33% of FLC Line)
