Product details

It carries 3 NO main contacts and is rated for 11 kW at both 500 V and 690 V, making it suitable for 400 V-class motors up to that power level in standard AC-3 duty. For demanding applications like reversing, inching, or plugging, the AC-4 rating of 15.5 A at 400 V defines the switching capability under high electrical stress — this is the figure to check when the load sees frequent starts or reversals under full current.

Main circuit connections use screw-type terminals accepting 2x (1 to 2.5 mm²) solid/stranded, 2x (2.5 to 6 mm²), or up to 2x 10 mm² — or AWG equivalents 2x (16 to 12), 2x (14 to 10), 1x 8.

For Type 2 coordination (contactor remains fully operational after a fault), the fuse must be limited to 35 A gL/gG. These values govern the upstream short-circuit protection device selection.

Auxiliary contacts and endurance

The integrated auxiliary contact block (1 NO + 0 NC) is rated for switching at various control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 2 A at 60 V, with lower ratings at 110 V (1 A) and 220 V (0.3 A). These cover typical PLC or relay interface signals.

Frequently asked questions

What are the key ratings for this contactor?

The 3RT1026-3AP00 is rated for 11 kW at both 500 V and 690 V in AC-3 duty, with an AC-4 current rating of 15.5 A at 400 V. It has 3 NO main contacts, mechanical endurance of 10 million cycles, and accepts screw-type terminals for wire sizes up to 2x 10 mm².

What are the physical dimensions for panel layout?

The S0 frame measures 45 mm width, 85 mm height, and 90 mm depth. It mounts on 35 mm DIN rail per DIN EN 50022 and supports side-by-side mounting without derating.

What short-circuit protection does this contactor require?

For Type 1 coordination, use a gL/gG fuse up to 100 A. For Type 2 coordination (full protection after fault), limit the fuse to 35 A gL/gG.

What compliance documentation is available?

The part carries a reference code per DIN EN 81346-2 (Q for switching devices). Standard Siemens SIRIUS documentation includes CE declaration of conformity and UL/CSA certifications; specific certificates are available on request through the RFQ process.
