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.

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)

CFLs work in a completely different way from ordinary lamps, they work by using a different process called fluorescence rather than generating light from heat. A typical light bulb wastes 90% of energy and converts only 10% of energy into light, this is where CFL has the biggest advantage. CFL- Curved or conical glass tube filled with argon and a small amount of mercury vapor. The inner wall of the glass is coated with fluorescent material. CFL- It is manufactured using the principle of creating fluorescent light. CFL- Originally white in color but now the construction and use of CFLs producing colored light has become popular.
