The Class 10 trip curve means it will not nuisance-trip on a normal motor start but still protects the winding during a stalled-rotor condition, which is the standard for most general-purpose motor applications. ## Mounting and panel fit Clearance spacings are specified: 50 mm upwards, 20 mm forwards, 10 mm downwards, and 20 mm at the side, with zero clearance needed backwards — this keeps the heat rise from the contactor from cooking adjacent components. ## Sourcing and lifecycle reality Listed as current production — this is not a legacy or phase-out SKU, so it can be specified into new BOMs without worrying about a last-time-buy window closing. Operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C — covers most panel environments without derating until you hit the upper end.","metaTitle":"Siemens 3RA2115-1EA16-5BB4-ZX95 SIRIUS Direct Starter","metaDescription":"Siemens 3RA2115-1EA16-5BB4-ZX95 SIRIUS direct-on-line starter, size S00, 4 A at 400 V AC-3, Class 10.
