Product details

Panel-fit and mounting

Dimensions are 121 mm depth, 45 mm width, 70 mm height — compact enough for dense panel layouts where space is tight.

The magnet coil uses spring-type terminals — no screwdriver needed for the coil connection, which speeds up panel wiring. Main contact terminals accept solid or stranded wire from 0.5 to 4 mm², and can take two conductors per terminal (2x 0.5 to 4 mm²).

Duty ratings and switching frequency

This contactor is rated for AC-1 (resistive), AC-2, AC-3, and AC-4 duty classes, with maximum switching frequencies: 1000 operations/hour at AC-1, 750/h at AC-2 and AC-3, and 250/h at AC-4. The AC-3e rating also caps at 750/h. These limits govern how fast you can cycle the contactor in motor-starting or resistive-load applications — exceeding them shortens life or causes weld risk. Switching capacity at DC voltages: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.14 A at 440 V. For DC loads, the arcing time is 4 to 15 ms at AC, and the contactor is rated for 0.25 A holding current at 50/60 Hz. Motor horsepower rating at 230 V is 0.75 hp — useful for small pump or fan motors in the sub-1 hp range.

Typical mechanical endurance is 10 million operations — a high-cycle figure that suits frequent switching in conveyor or packaging lines.

Frequently asked questions

What are the key dimensions of 3RT2015-2CP04-3MA0?

Depth is 121 mm, width is 45 mm, height is 70 mm. It mounts on 35 mm DIN rail per DIN EN 60715.

What wire sizes does the 3RT2015-2CP04-3MA0 accept?

Solid or stranded wire from 0.5 to 4 mm², and it can take two conductors per terminal (2x 0.5 to 4 mm²). The coil uses spring-type terminals.

Will 3RT2015-2CP04-3MA0 drop into a panel specified around 3RT2015-2AP02 without rewiring?

Both are Size S00 contactors with the same footprint and DIN-rail mounting, so the mechanical fit is identical. The terminal type differs: the -2CP04-3MA0 uses spring-type coil terminals, while the -2AP02 uses screw-type. If your panel wiring expects screw terminals, the spring-type coil connection may require a different wiring approach, but the main power terminals are compatible.
