Direct start with magnetothermal wiring

Direct start with magnetothermal wiring:

This diagram shows how to make direct start with magnetothermal wiring. In this circuit, we use a TP MCB ( Tripple Pole Minature Circuit Brekaer ), a DP MCB ( Double Pole Minature Circuit Breaker ), and a Magnetic contactor. First, we need to connect the DP MCB and TP MCB with power source then connect the magetic contactor with the power source. Now it's ready for use.

Components used to make the MCB wiring:

01. TP MCB

Fig 2: TP MCB

Three wires can be controlled by a triple pole MCB. Triple pole MCB circuit breakers are generally used in three-phase lines. A triple-pole MCB circuit breaker has three wires at its input and three wires at its output. But one can use this circuit breaker in a single-phase line. TP MCB widely used in industries. The reason is that it has three poles. And this TP circuit breaker is used to provide three-phase and three-phase connections. A neutral is not normally used in three-phase lines. But a 4-pole MCB circuit breaker is used if needed.

02. DP MCB

Fig 3: DP MCB

Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

03. Contactor 

Fig 4: Contactor

A magnetic contactor is an electrical device used for load control, automation, and protection. It is much like a magnetic reel. However, relays are generally used for low power and voltage, on the other hand, when we think of high power, these heavy-duty contractors only come to mind. It basically works by switching the load on and off. It has 3 terminals whose inputs are denoted as L1, L2, L3, and outputs as T1, T2, and T3. The circuit of the load is made in automation mode or protection using auxiliary contacts. It has two types of terminals. 1) Normally Open (NO). 2) Normally Closed (NC)
