Socomec 38513038F J400A 3-Phase Disconnect Switch

Socomec FUSERBLOC J400A F/L, reference 38513038, is a manually operated three-pole fusible disconnect switch designed to safely isolate power in industrial electrical installations. It is rated for 400 A per pole, with voltage ratings up to 600 V AC and 250 V DC, and is part of the FUSERBLOC UL family. The J400A designation identifies a 3P, 400 A per-pole device, with the F/L variant noted within the model line. The switch uses double-break contacts per pole to ensure full isolation of the fuse when OFF, reinforcing safety during maintenance and service. This configuration supports integration into multi‑circuit control panels and power distribution setups where a fusible disconnect is required for protection and isolation. With a three‑phase, 400 A per-pole rating, it is well-suited to OEM panel builders and service engineers seeking a reliable, UL-listed isolation solution inside industrial equipment.
