Product details

Rated at 45 kW in AC-2 duty at 400 V, this contactor handles slip-ring motor reversing and plugging applications. In AC-4 duty at 400 V it carries 80 A, covering inching and reversing of squirrel-cage motors. At 500 V it delivers 55 kW, and at 690 V it delivers 25.4 kW — useful for higher-voltage motor circuits common in European and export panels. The auxiliary contact block is rated for 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V DC — enough for PLC-level signal switching and relay interposing. Main contacts handle 230 V at 6 A and 400 V at 3 A for resistive loads. Maximum switching rates: 900 cycles/hour at AC-1, 350 at AC-2, 850 at AC-3, and 250 at AC-4. The operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, with pollution degree 3 for industrial environments. Front-side protection is IP20 with cover or box terminal; the terminal itself is IP00. Wire capacity: solid 2x (0.25...2.5 mm²) for control, stranded 2x (10...50 mm²) for power, and 2x (2.5...16 mm²) for mixed connections. The contactor is RoHS compliant with substance prohibition date of May 1, 2012, and operates at 50 Hz rated frequency with a voltage operating range of 0.8...1.1 at 50 Hz.

Dimensions: 146 mm height, 70 mm width, 139 mm depth. The 70 mm width matches the S3 frame footprint — verify clearance for the arc chute and auxiliary contact block if adding one. Screw terminals accept up to 50 mm² stranded on the power side; use ferrules for stranded conductors to avoid whiskers under the screw head. The IP20 front cover is adequate for most enclosed panels; if the contactor is mounted near the gland plate, maintain at least the IP00 clearance for the live terminals.

Frequently asked questions

What are the key motor ratings for this contactor?

It is rated 45 kW at 400 V AC-2, 80 A at AC-4 at 400 V, 55 kW at 500 V, and 25.4 kW at 690 V. The AC-3 rating is not explicitly listed, but the AC-2 and AC-4 ratings cover the heavy-duty motor switching profiles.

What wire sizes does the screw terminal accept?

For the main power circuit, it accepts stranded conductors 2x (10...50 mm²). For control wiring, solid 2x (0.25...2.5 mm²). Mixed connections use 2x (2.5...16 mm²) solid or stranded.

What is the mechanical life and switching rate?

Mechanical life is 10,000,000 operations typical. Maximum switching rates: 900 cycles/hour at AC-1, 350 at AC-2, 850 at AC-3, and 250 at AC-4.

What compliance documentation is available?

The contactor is RoHS compliant with a substance prohibition date of May 1, 2012. It is rated for pollution degree 3 and operates at 50 Hz. Standard Siemens documentation includes the declaration of conformity for the SIRIUS series.
