What is the breaking capacity (6kA vs 10kA)?

Breaking capacity (Icu) is the maximum short-circuit current the breaker can safely trip without damaging itself. 6kA is standard for normal residential wiring. 10kA (like NXB-63H) is used for commercial buildings, solar installations, or locations near grid transformers.

How do I choose the correct Ampere rating (e.g. 10A, 20A, 32A, 63A)?

The Ampere rating must match the load. For example: 6A/10A for lights and fans, 16A/20A for ACs and geysers, 32A/40A for main distribution lines or high-power sub-circuits, and 63A for single-phase main switches.

Frequently Asked FAQs

Answer

An MCB is an electromagnetic switch that automatically cuts off electricity when the current exceeds safe limits. It protects wiring against Overloads (running too many devices) and Short Circuits (live and neutral wires touching).

جواب (اردو)

ایم سی بی ایک خودکار سوئچ ہے جو وائرنگ کو اوور لوڈ (زیادہ لوڈ چلانے) اور شارٹ سرکٹ (تاروں کے باہم ٹکرانے) سے بچاتا ہے۔ کرنٹ زیادہ ہونے پر یہ خودکار طور پر بجلی بند کر دیتا ہے۔
