Product details

Capacitor switching on a DIN-rail footprint

The Siemens 3RT2617-1AF03 is a SIRIUS capacitor contactor in Size S00, purpose-built for switching capacitor banks in power-factor correction panels. The operating temperature range is -25 to +60 °C, and the contactor can be rotated ±180° on a vertical surface or tilted ±22.5° — useful when the panel layout forces an unconventional orientation.

The coil and main terminals use screw-type connections. Solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² per clamp. At 40 °C ambient, a single 4 mm² or two 2.5 mm² conductors are the maximum; at 60 °C, two 4 mm² conductors are allowed — derate the wire count, not the cross-section, when the panel runs hot.

Frequently asked questions

Where can I buy 3RT2617-1AF03?

It is sourced and quoted to order against an RFQ through independent distribution channels; availability and current pricing are confirmed at quote time.

What is the switching capacity of 3RT2617-1AF03 at 400 V?

It is rated 3 A at 400 V AC, with an arcing time of 10 to 15 ms, designed for capacitor bank switching.

What wire sizes does 3RT2617-1AF03 accept?

Screw terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² per clamp.

Will 3RT2617-1AF03 fit a panel designed for 3RT1025-1AN24?

Both are Size S00 contactors on a 45 mm DIN-rail footprint, so the mechanical fit is the same — but 3RT1025-1AN24 is a general-purpose contactor, not a capacitor-rated one, so verify the inrush duty before substituting.
