Product details

The coil is 24 VDC with screw-type terminals, and the main contacts are rated for switching at several voltage levels: 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, and 0.2 A at 440 V. At 230 V it carries a 1 hp motor load. These ratings define the actual load it can break — match your motor FLA against the appropriate voltage column. Mechanical switching frequency varies by duty: up to 1 000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-2 and AC-3 (motor starting/running), and 250 cycles/hour at AC-4 (plugging/inching). For AC-3e the rate is also 750 cycles/hour. The arcing time is 10 to 15 ms at AC, and the contactor's typical mechanical life is 10 000 000 operations.

Dimensions are 45 mm wide, 58 mm high, and 117 mm deep — a standard S00 footprint that fits alongside other S00 contactors and overload relays on the same DIN rail. Wire terminations accept solid or stranded conductors from 0.5 to 4 mm², with dual-wire capability: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².

Frequently asked questions

What are the key ratings for the 3RT2016-1CU07?

The contactor is rated 6 A at 24 VDC, 3 A at 400 VAC, and 1 hp at 230 VAC. Mechanical life is 10 000 000 operations, and switching frequency is up to 1 000 cycles/hour at AC-1 duty.

What wire sizes does the 3RT2016-1CU07 accept?

It accepts solid or stranded conductors from 0.5 to 4 mm², including dual-wire combinations up to 2x 4 mm².

Does the 3RT2016-1CU07 include an auxiliary contact block?

No, this variant has no auxiliary switch. A separate side-mount auxiliary contact block must be ordered if needed.
