Motor protection and reversing duty
Reversing starter configuration (two contactors mechanically interlocked) handles forward/reverse control for conveyors, hoists, or pump direction changes without external interlocking relays. Rated for 750 W at 400 V (AC-3) and 1.5 hp at 575/600 V — the full voltage range from 200 V to 690 V AC-3 is covered, so it fits North American and IEC motor ratings on the same device.
Snap-on DIN rail mounting and dimensions
Snap-on fastening onto a 35 mm standard DIN rail — no tools needed for installation; vertical mounting position only. Dimensions: 90 mm wide, 130 mm deep, 265 mm tall. Clearance requirements: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the side — factor these into panel layout to avoid thermal derating.
Environmental and compliance
Pollution degree 3 (conductive pollution or dry non-conductive that becomes conductive due to condensation — typical for industrial control panels).
