Switchgear

👉 Terminal Blocks

     A terminal block is a screw-type electrical connector where the wires are clamped to the metal part by a screw.

👉 ELCB

     It is used for the protection against electrical leakage in the circuit. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, ELCB cuts off the power within the time of 0.1 s automatically protecting the personal safety and preventing the equipment from the fault.

     ELCB also protect the circuit against over load and short-circuit.

👉 Miniature Circuit Breaker (MCB)
     It is used for protecting the circuit against overload and short circuit. It can be used in lighting and electric motor distribution system.

👉 Moulded Case Circuit Breaker (MCCB)
     It is used to control electric energy in distribution network and is having overhead and short circuit protection.

👉 Contactor

     A contactor is an electrically-controlled switch used for switching an electrical power circuit. 

     A contactor is typically controlled by a circuit, which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.

👉 Star - Delta Starter

     Star-Delta starter is generally used for controlling motors above 7.5 hp and consist of following: 

• One main contactor 
• One star contactor 
• One delta contactor 
• One on-delay timer 
• One overload relay 
• Set of auxiliary control contacts
