| ASKB2 series household miniature circuit breakers are suitable for the end power distribution lines of office buildings, residences and general industrial use. ASKB2 can protect lines against overload and short-circuit, and provide functions of isolation and control. Under normal conditions, MCB can also be used in infrequent on-off control of electrical devices and lighting lines. The MCB are suitable for AC 50/60Hz, rated voltage below 230V, rated current below 32A. |

FAQ
1. What are the rated current specs of ASKB2 series miniature circuit breakers?
- 32(A) frame: 3, 6, 10, 16, 20, 25, 32A
2. How does an MCB work?
-Overload Protection: A bimetallic strip heats up and bends, triggering the trip mechanism (thermal tripping).
-Short-Circuit Protection: An electromagnetic coil generates a magnetic force to instantly trip the mechanism (magnetic tripping).
-Manual Operation: Supports manual ON/OFF switching; some models allow remote control.
3. What Are the Common Types of MCBs?
-By Tripping Curve:
Type B (3–5× rated current): For residential/lighting circuits.
Type C (5–10× rated current): For motors and inductive loads.
Type D (10–20× rated current): For high inrush currents (e.g., transformers, compressors).
4. How to Select the Right MCB Current Rating?
Match Load Current: MCB rating should slightly exceed the circuit’s operating current (e.g., 16A MCB for a 10A load).
Consider Starting Current: Motors require higher tripping curves (Type C/D).
Cable Compatibility: Ensure the MCB protects the wire gauge (e.g., 2.5mm² copper cable pairs with 16A–20A MCB per local standards).
