The 3RA2210-0GA15-2BB4: The 0.63 A at 400 V AC-3 rating means it switches a motor load up to about 0.25 kW at 400 V, with the reversing contactor pair interlocked mechanically and electrically to prevent both directions closing together. The 24 V coil is standard for control circuits in industrial panels — the 50/60 Hz operating frequency means it works on either mains frequency without derating.
Class 10 thermal overload and magnetic short-circuit trip
Trip Class 10 means the overload relay trips within 10 seconds at 600% of the set current — fast enough to protect a standard squirrel-cage motor during a stalled-rotor condition. The overload release is thermal bimetallic, so it tracks the motor's I²t heating curve naturally; the short-circuit trip is magnetic for instantaneous response on a hard fault. The supplied contactor is 3RT2015-1BB42 and the link module is 3RA1921-1DA00 — the assembly arrives as a coordinated reversing starter, not a field-built combination.
DIN rail mounting and panel clearances
Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, 0 mm backwards — the backwards clearance of zero means it can sit flush against a back panel or busbar support.
