💡 Product Features and Applications

K-Type Trip Curve: This is the core feature of this product. The K-type curve has a high magnetic trip threshold (typically between 8-14 times the rated current), enabling it to withstand the large instantaneous inrush current (typically 5-8 times the rated current) generated when inductive loads such as motors start, thus avoiding false tripping while still providing effective short-circuit protection.

Dual Protection Mechanism: An integrated delayed thermal trip mechanism for overload protection and an electromagnetic trip mechanism for short-circuit protection ensure rapid and safe circuit disconnection under fault conditions.

Compact Design: A single-pole modular design with a width of only 17.5mm saves distribution box space and facilitates installation and maintenance.

Main Applications: Particularly suitable for protecting small motors, transformers, and control circuits. Also commonly used in specific power distribution circuits in residential, commercial, and industrial buildings.

⚠️ Selection and Installation Notes

Accessory Compatibility: Please note that accessories (such as auxiliary contacts, alarm contacts, etc.) from ABB’s System Pro M Compact series and Classic series are not interchangeable.

Professional Installation: Electrical installation work must be carried out by qualified professional electricians and must strictly comply with local electrical installation codes and safety standards.
