Product details

Power wiring accepts stranded conductors from 16 to 70 mm². The auxiliary circuit uses screw-type terminals accepting 2x 0.5–1.5 mm² solid or 2x 0.75–2.5 mm² stranded, max 2x 4 mm².

Duty-cycle capability — the rating that governs real use

Maximum switching frequency: 800 operations/hour in AC-1, 400 in AC-2, 1,000 in AC-3, 130 in AC-4. AC-3e rating also at 1,000 ops/h. Arcing time runs 10–15 ms; total opening time (including arc extinction) is 40–60 ms for both AC and DC coils.

Auxiliary contact capacity

Built-in auxiliary switch rated for 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. These are the continuous current limits for the auxiliary contacts feeding PLC inputs, indicator lamps, or interlocking relays.

Environmental and clearance

These are the free-air spacing requirements for heat dissipation and arc flash — a panel layout that crowds the contactor below these distances will derate the switching capacity.

Frequently asked questions

What are the overall dimensions of 3RT1054-1AT36?

Depth 170 mm, width 120 mm, height 172 mm. These are the envelope dimensions for panel layout and enclosure sizing.

What wire sizes does 3RT1054-1AT36 accept on the power and auxiliary terminals?

Power terminals accept stranded conductors 16–70 mm². Auxiliary screw terminals accept 2x 0.5–1.5 mm² solid or 2x 0.75–2.5 mm² stranded, up to 2x 4 mm² maximum.
