Product details

What this SIRIUS direct starter delivers

The 3RA2110-0KE15-1BB4: This is a factory-assembled direct-on-line motor starter from the Siemens SIRIUS range, size S00 — the smallest frame in the family, intended for fractional-horsepower motors up to about 0.75 hp at 460/480 V.

Mounting and panel clearance — the S00 footprint

Width is 45 mm, height 198 mm, depth 97 mm. The mounting position must be vertical — the bimetallic overload relies on natural convection for its trip curve, and a horizontal mount shifts the thermal response enough to nuisance-trip or fail to protect. Clearance requirements: 50 mm above, 20 mm below, 20 mm to the side, and 20 mm forward — no rear clearance needed.
