It uses a thermal-magnetic trip unit, with a rated current of 1 A and a magnetic tripping threshold of 22 A — meaning it protects against overloads (thermal) and short-circuits (magnetic) in one compact device. Rated for uninterrupted duty per IEC 60947-4-1, it is suitable for continuous motor loads.
IP20 finger-safe protection (IEC 60529) and IK04 impact resistance suit it for enclosed panel installation. Climatic withstand per IACS covers marine and humid environments.
