Product details

Integrator note — 3RT1017-5BB42

The Siemens 3RT1017-5BB42 is a SIRIUS power contactor in size S00, rated for 5.5 kW at 400 V AC-2 and 8.5 A at 400 V AC-4. Three NO main contacts, three poles, IP20 on the front face.

DIN-rail fit and panel clearance

Width 45 mm, height 60 mm, depth 73 mm. The 6 mm clearance to adjacent devices at the side is the minimum air gap — no extra spacer needed for a standard panel layout. Pollution degree 3 rated, so it handles conductive dust environments typical of industrial control cabinets.

The AC-12 operating current max is 10 A — that's the resistive load ceiling for the main circuit.

Frequently asked questions

What is the coil voltage for 3RT1017-5BB42?

24 V DC rated coil. Closing and holding power is 3.3 W DC — no separate economy resistor needed.

Where can I buy 3RT1017-5BB42?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
