The GS1PPB3 is a TeSys GS fuse switch disconnector body — the base unit you mount and wire, then fit the appropriate fuse carrier and handle. It's a three-pole (3P) device rated for 315 A at 400 V in AC-23B duty, which covers motor switching with occasional overloads. It accepts BS-type fuses (sizes B1, B3, B2) and is designed for either rail or plate mounting. For the commissioning engineer: this is a heavy-duty disconnect body. Power connections are via bars or screw terminals accepting 185 to 240 mm² flexible cable. The control circuit and power circuit both torque to 25 N·m on screw terminals. Mechanical durability is 10 000 cycles, electrical durability is 1000 cycles at AC-23A/B and only 200 cycles at DC-23A/B — if your application is DC, factor that into maintenance intervals.
The headline rated operational current of 315 A at 400 V AC-23B is the number that decides whether this body fits your motor circuit. That 315 A is also its conventional free-air thermal current (Ith) at 40 °C, so it's not a burst rating — it can carry that continuously in open air. The making capacity is 3150 A at 400 V AC-23B, and the short-circuit withstand is 80 kA, which tells you the fuse holder and body can handle a high-energy fault without bursting. For the panel OEM: the body dimensions are 271 mm wide, 205 mm high, and 149 mm deep. The operating handle can be mounted externally on the front or right side, which helps with panel layout.
