Description
Part of the Multi 9 series, this 40-amp supplementary protector delivers targeted overcurrent defense for industrial equipment. It is specifically engineered to provide additional protection within appliances where branch circuit breakers are already present. The unit installs onto standard 35mm DIN rails inside OEM control panels. Featuring a B-curve thermal-magnetic profile, it trips between 3 and 5 times the rated current to safeguard sensitive components. Replaced by the M9F22240 model.Specifications
