Product details

Dimensions are 210 mm height, 145 mm width, 202 mm depth. The main circuit uses screw-type terminals accepting 2/0 to 500 kcmil AWG or 185 mm² minimum conductor at both 40 °C and 60 °C.

Electrical Ratings & Duty Cycles

Rated insulation voltage is 1 000 V. The contactor carries a mechanical life of 10 000 000 operations typical. Switching frequency varies by duty: 2 000 operations per hour for both AC and DC general use, up to 800 1/h in AC-1 (resistive) duty, 700 1/h in AC-3 (motor starting), and 130 1/h in AC-4 (plugging/reversing). The coil circuit is rated for 6 A at 24 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. A built-in varistor surge suppressor handles coil transients — no external snubber needed for standard PLC or relay outputs.

Frequently asked questions

What is 3RT5065-6AD36's closest functional second-source — 3RT5065-6AB36?

The 3RT5065-6AB36 uses a 24 V AC coil (versus 42-48 V AC on the -6AD36) but shares the same S10 frame, screw terminals, and power ratings. It will drop into the same panel footprint without rewiring the main power circuit, but the coil supply must match. The 3RT5065-6AP36 uses a 110-127 V AC coil, and the 3RT5065-6NF36 uses a 42-48 V DC coil — so if you need DC control, the -6NF36 is the functional equivalent for the coil voltage.

Will 3RT5065-6AD36 drop into a panel that was specified around 3RT5065-6AB36 without rewiring?

Yes, the physical footprint is identical — both are S10 size with the same mounting pattern and screw terminals. The only difference is the coil voltage: the -6AD36 requires 42-48 V AC, while the -6AB36 uses 24 V AC. If the panel's control transformer and wiring are already set for 42-48 V, it drops in directly. If not, the coil circuit must be re-fed.

What compliance documentation does this brand provide for 3RT5065-6AD36 (RoHS, REACH, UL, IEC)?

The substance prohibitance date of 03/01/2017 confirms RoHS and REACH compliance for EU markets. The rated insulation voltage of 1 000 V and pollution degree 3 align with IEC 60947-4-1 for contactors. UL and CSA listings are standard for the SIRIUS series, though specific file numbers are not in this evidence set.

Where can I buy 3RT5065-6AD36 and how is it quoted?
