Berikut di bawah ini perbedaan MCB DC dan MCB AC: 1. Dilihat dari Jenis Arus: 2. Dilihat dari Karakteristik Pemutusan: 3. Dilihat dari Struktur dan Konstruksi: MCB DC: Beda dengan instalasi listrik / rangkaian listrik AC, arus listrik DC punya arus yang konstan dan tidak bolak-balik. Karena tidak ada mempunyai tegangan 0 V, maka MCB AC tidak

Figure 1 below shows an AC current waveform after a fault current situation occurs. Figure 1: AC current waveform behavior after a short circuit fault (Source: Littelfuse, 2007) When selecting the proper fuse, it is important to look at the peak let-through current, I peak (Ampere) and nominal melting, I 2 t (Ampere Squared Seconds), ratings.

The minimum circuit ampacity also tells us the minimum size of the circuit breaker; it needs to be sized large enough to help prevent nuisance tripping when the air conditioner first turns on. Circuit Breaker Size. To determine the right circuit breaker size for an air conditioner, we look at both the minimum and maximum size allowable.
Every device has an operating temperature. Even if you have a temperature-compensated MCB, a high ambient temperature (above 40°C) can be the reason for tripping. You should ventilate your enclosure to avoid high temperatures. If there is abnormal heating due to the loosening of the screw at the terminal part.
RCBO devices are a combination an RCD and an MCB in one device. An RCD also detects earth leakage which has become another keen topic within the 18th edition wiring regulations. Currently in residential installations it is common to find one or more RCD’s used alongside MCB’s within the Consumer unit.
Tripping Characteristics of MCB: B,C,D,K,Z Trip Curves. electricalterminology 3 years ago. Circuit-breakers are used to protect cables in installations. They should disconnect automatically as soon as the combination of the current rise and duration causes the cable or a component to heat up excessively. Circuit-breakers are used for overload
By Interrupting Mechanism. There are many different types of interrupting mechanisms in circuit breakers. Basically, the interrupting mechanism stops the current flow and shuts off the power. The most common types are air, oil, vacuum, MCCB, and ICCB. Here is how the different types work. G series MCB: G series MCBs are designed to protect circuits with inductive loads. These are suitable for protection of motors, air conditioners, hand tools, halogen lamps, etc. DC series MCB: DC series MCBs are suitable for voltage up to 220 V DC and have a breaking capacity up to 6 kA. The tripping characteristics are similar to the L and G
