Description
Built for demanding industrial applications, this 30A supplementary protector from the Square D Multi 9 series provides reliable overcurrent protection. The three-pole unit mounts onto standard 35mm DIN rails, offering a compact footprint for OEM panels. It functions as a direct replacement for older installations and can be substituted with the M9F23330 model. Equipped with a D-curve thermal-magnetic trip mechanism, it allows for magnetic tripping at 10 to 14 times the rated current.Specifications
