The Schneider Electric GS1PPB4 is a TeSys GS fuse switch disconnector body, 4-pole, designed for BS-type fuses (sizes B1, B2, B3). It serves as a manual disconnect and protection device in AC and DC networks, rated for 50/60 Hz. The conventional free air thermal current (Ith) is also 315 A at 40 °C.
Short-circuit withstand rating is 80 kA — this is the fault current the device can survive in a through-fault condition without rupturing, assuming upstream protection coordinates. Making capacity is 3150 A at 400 V AC-23B, which is the peak current the switch can close onto without welding or damage. Rated short-circuit making capacity (Icm) is 315 kA at 400 V with protection by BS fuses — that figure reflects the fuse's ability to limit the let-through energy. Rated operational power is 132 kW at 400 V and 220 kW at 690 V. IP20 with terminal cover per IEC 60529 — finger-safe but not washdown-rated; mount inside a panel with a higher overall enclosure rating.
Mounts on a rail or plate (mounting support: rail, plate). The external operating handle can be fitted on the right side or front, giving flexibility for panel layout. Power connections are via bars or screw terminals accepting 185...240 mm² flexible cable.
If you need a drop-in replacement, you will need to cross-reference the functional ratings (315 A, 4P, BS fuses, AC-23B duty) against current TeSys GS or TeSys GV products. We can source the GS1PPB4 against an RFQ — let me be transparent: availability and pricing vary with the batch, but we can locate genuine units.
