Product details

The spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded wire, so no ferrule crimping is required for the power connections — a time-saver during panel wiring.

The contactor's switching capacity is defined by duty-specific current ratings: at 230 V rated value it handles 6 A, at 400 V rated value 3 A, and at 60 V rated value 2 A. These are the numbers that govern real motor and resistive loads — not a single headline figure. The auxiliary contacts (1 NO + 1 NC) each carry 12 A rated value, enough for pilot duty on contactors or small relays.

Mounting and integration into a DIN-rail panel

The 45 mm width, 60 mm height, and 72 mm depth mean it occupies a single 45 mm module on the rail — standard for size S00 contactors.

Frequently asked questions

What is the depth of 3RT1517-2BP40?

The depth is 72 mm.

What wire size does the spring-loaded terminal accept?

The spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded wire.

Will 3RT1517-2BP40 drop into a panel specified around 3RT1016-2AP02?

Both are size S00 contactors on the same 45 mm DIN-rail footprint, so the mechanical fit is the same. The 3RT1517-2BP40 uses spring-loaded terminals versus screw terminals on the 3RT1016-2AP02, so wiring method differs but the panel layout does not need re-drilling.
