Product details

The 10 A rated operational current at 24 V (AC-1 duty) means it handles resistive loads up to that current; for motor duty (AC-3), the rated current is lower, so size for the actual motor FLA, not the contactor's maximum.

The 45 mm width and 58 mm height fit standard S00 footprint enclosures. Depth of 73 mm leaves clearance for wiring and auxiliary contact blocks. Accepts solid or stranded conductors from 0.5 to 4 mm², with dual-wire capability up to 2x 2.5 mm².

Switching performance and thermal limits

Maximum switching frequency varies by duty: 1 000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor start/run), and 250/h at AC-4 (plugging/inching).

Frequently asked questions

What is the closest functional second-source for 3RT2016-1AH02?

The closest functional sibling is 3RT2016-1AB01-ZX95. Both share the same S00 frame size and 24 VDC coil, but the -ZX95 suffix may indicate special auxiliary contact configurations or customer-specific markings. Verify the auxiliary contact arrangement before substituting.

What are the key dimensions of 3RT2016-1AH02?

Width 45 mm, height 58 mm, depth 73 mm. It fits the standard S00 contactor footprint and mounts on 35 mm DIN rail.

What wire sizes does 3RT2016-1AH02 accept?

Solid or stranded conductors from 0.5 to 4 mm². Dual-wire capability supports 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm².

Will 3RT2016-1AH02 drop into a panel specified around 3RT2016-1AB01-ZX95?

Physically yes — same S00 frame, same 45 mm width, same DIN rail mounting. The coil voltage is identical at 24 VDC. However, the auxiliary contact arrangement may differ between the standard -1AH02 and the -ZX95 variant, so check the auxiliary switch configuration before finalizing.
