Description
Operating as a non-automatic disconnect, the Siemens JJ3S400 provides reliable circuit isolation for commercial and industrial applications. This 400-amp, 3-pole molded case switch is designed without overcurrent protection, serving purely as a manual switching device. It bolts into Siemens P4 and P5 panelboards, as well as compatible switchboards. Rated for 600VAC with a 25kA short-circuit withstand rating at 480VAC, this legacy J-frame unit is replaced by the JXD63S400 in newer systems.Specifications
