| ASKB6 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 40A. The MCB adopts the innovative "phase line+ N line" design, which can cut off the phase and neutral lines at the same time, achieving higher safety performance and avoiding personal and fire hazards caused by reverse wiring of the phase and neutral lines or high neutral-to-ground potential when using single-pole circuit breakers. The compact design makes its thickness only 18mm, which fully meets the high standard requirements for compo-nent volume of household distribution box. MCB has high breaking capacity, adopts modular design, and can be used with a variety of accessories to meet customers' requirements for other additional functions. |

FAQ
1. What are the rated current specs of ASKB6 series miniature circuit breakers?
- 40(A) frame: 6, 10, 16, 20, 25, 32
2. What do the trip curves (B/C/D/K/Z) mean?
-Type B (3–5× In): Homes (sensitive devices like electronics).
-Type C (5–10× In): Commercial (motors, fluorescent lighting).
-Type D (10–20× In): Industrial (high inrush currents, transformers).
-Type K/Z: Specialized (semiconductors, medical equipment).
3. Does MCB wiring direction matter?
Yes! Most MCBs label "LINE" (input) and "LOAD" (output). Reverse wiring may affect performance or safety.
4. MCB trips but won’t reset – What to do?
-Disconnect all loads and try resetting.
-If it still trips, check for short circuits (use a multimeter).
-Replace the MCB if defective.
5. What If an MCB Won't Reset After Tripping?
Possible Causes:
Persistent short circuit/ground fault.
MCB mechanism failure (e.g., failed to reset).
Solution: Inspect wiring or replace the MCB.
7. Can MCBs Be Used in DC Circuits?
Standard MCBs: Designed for AC; DC use requires special models (DC MCBs).
DC Ratings: Check manufacturer specs (e.g., 24V/48V DC systems in solar panels).
Arc Extinction: DC arcs are harder to interrupt, needing higher breaking capacity.
