Specification Summary for Procurement
The 3RT1016-1AT62: Mounting is via screw or snap-on onto a 35 mm standard mounting rail per DIN EN 50022, which is the standard DIN rail profile for panel integration. Side-by-side mounting is permitted with a 6 mm clearance required at the side for heat dissipation. The main circuit uses screw-type terminals, accepting conductors from 2x (0.5... 1.5 mm²) up to a maximum of 2x (0.75... 4 mm²) or 1x 12 AWG. The front and terminal faces are rated IP20 for finger-safe installation within an enclosure.
Switching Performance and Application
For motor switching duty, the contactor is rated at 4 kW at 400 V in AC-2 duty (slip-ring motor starting) and 8.5 A at 400 V in AC-4 duty (plugging/inching of squirrel-cage motors). At 690 V, the motor power rating is 5.5 kW; at 500 V, it is 4.5 kW. These ratings define the maximum motor load the contactor can switch under those specific duty cycles. The auxiliary contact block provides switching capability at multiple voltage levels: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V. The mechanical service life is rated at 30,000,000 operating cycles typical. For short-circuit protection, the specification requires a gL/gG fuse rated at 20 A for Type 2 coordination (no damage to the contactor) and 35 A for Type 1 coordination (contactor may need replacement after fault).
Environmental and Installation Conditions
The contactor is rated for operation in ambient temperatures from -25 °C to +60 °C, with a pollution degree of 3 (conductive pollution or dry non-conductive pollution that becomes conductive due to condensation). Maximum operating altitude is 2,000 m above sea level. Physical dimensions are 45 mm width, 57.5 mm height, and 72 mm depth, fitting the standard S00 footprint for panel layout planning.
