ICHYTI shunt trip ac mccb FAQ

Q: How do I choose a MCB for DC?

A: To ensure proper selection of a suitable MCB for a DC circuit, it is essential to first determine the total current of the circuit. Once the current is determined, the appropriate MCB can be selected accordingly. It is important to note that the current rating of the MCB should not exceed the cable's current carrying capacity. Therefore, it is necessary to carefully match the MCB's current rating with the cable's capacity to avoid any potential hazards or damages.

Q: What are the advantages of DC circuit breaker?

A: Circuit breakers in DC circuits serve two main purposes: protecting individual loads that operate on DC power, and safeguarding primary circuits such as those found in inverters, solar PV arrays, or battery banks.

Q: What is the capacity of DC MCB?

A: When selecting a DC MCB, it is important to consider the breaking capacity required for the specific application. Residential DC MCBs typically have a breaking capacity of up to six kA, while industrial-grade DC MCBs are designed to handle higher breaking capacities. Therefore, it is essential to evaluate the application and select a DC MCB with an appropriate breaking capacity to ensure safe and reliable operation of the circuit.
