Product Q&A

Q:What protection functions does this MCCB provide?

It provides overload, short circuit, undervoltage, and overvoltage (OVP) protection to safeguard lines and power equipment.

Q:What are the available breaking capacity levels?

The breakers are classified into four levels: C type (economic), L type (standard), M type (medium breaking), and H type (high breaking).

Q:What is the rated current range?

The rated working current is up to 630A. Specific models like ARM3-160 offer frame sizes from 16A to 160A.

Q:Can the circuit breaker be installed in different orientations?

Yes, it can be installed vertically (upright) or horizontally (transversely) and includes an isolation function.

Q:What materials are used for the contacts and insulation?

It uses alloy contacts with high silver content, high-quality high carbon steel for mechanism parts, and unique thermosetting insulating material with high strength and flame retardancy.
