Circuit Breakers And Distribution Boards

MCB – These are an alternative to fuses and are used to protect circuits from excess current. These miniature circuit breakers (MCBs) are automatic switches which open when the current flowing through them exceeds the value for which they have been set. Several different MCB types are available – types A, B, C, D, K, and Z. However, the three key versions are type B, type C, and type D. Each is designed to be responsive to the likely strength of electrical surges in different settings. SP ( Single Pole ) MCB: In Single Pole MCCB, switching & protection are affected in only one phase.
DP ( Double Pole ) MCB: In Two Pole MCCB, switching & protection are affected in phases and the neutral.
TP ( Triple Pole) MCB: Only three phases of the circuit are switched and protected by a triple/three-phase micro circuit breaker, not the neutral.
TPN (3P+N) MCB: A TPN MCB has switching and protection for all three phases of the circuit, and Neutral is also included as a separate pole.
4 Pole MCB: A four-pole MCB is similar to a TPN, but it also has a neutral-pole protective release. Types of Circuit Breakers. MCB, MCCB, RCD, RCCB, RCBO, ELCB, RCCB, ACB, VCB, MOCB, BOCB, SF6 CB, GFCI, MPCB, HVDC, DC-CB, Auto CB.

Distribution board – A distribution board (also known as panelboard, breaker panel, electric panel, DB board or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure. It is important to understand the different purposes of the distribution board. Bearing industrial uses in mind, different boards are suggested based on electricity and power usage and usage of cost-efficiency products. Here are some of the types of distribution boards used in industries: Motor Control Centers (MCCs), User-Friendly Human Machine, Interface (HMI), Operator Panels, Industrial Hydraulic Control Panels, Programmable Logic Controller (PLC) Panels and Industrial Hydraulic Control Panels
