The 3RA2215-1AA16-2BB4-ZX95: It ships as a pre-assembled unit with a 3RT2016-1BB42 contactor and a 3RA1921-1DA00 link module, plus a thermal bimetallic overload relay set to Trip Class 10 — so it protects the motor against overloads while allowing the short starting inrush typical of standard squirrel-cage motors.
Mounting and panel fit — screw and snap-on DIN rail
Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, and 0 mm backwards — the zero backward clearance means the unit can sit flush against the back panel, saving rail space.
Duty ratings and operating range
The coil is rated 24 V DC (24... 24 V), and the operating temperature range is -20 to +60 °C during operation, with storage and transport limits of -50 to +80 °C — the -20 °C floor matters for unheated enclosures in cold climates.
