Description
Part of the Multi9 C60N series, this 40A supplementary protector delivers reliable thermal-magnetic protection for industrial applications. It safeguards sensitive equipment and control circuits against overcurrent events. Mounting onto standard 35mm DIN rail systems, this three-pole unit integrates into OEM control panels. This legacy component is replaced by the M9F22340 model in newer installations. Featuring a C-curve trip profile, it handles moderate inrush currents effectively.Specifications
