Starter Control Panel

MCCB (Main Circuit Breaker): Protects against short-circuits on the main power supply. 

Contactors: Typically three – Main (K1), Star (K2), and Delta (K3). Mechanical and electrical interlocks prevent simultaneous star and delta engagement.

Overload Relay: Senses motor overcurrent and trips the circuit to protect the motor. 

Motor Terminals: Provide connection points for the motor’s six winding leads.
