Product details

Siemens 5SP9240-7KC47 — 2-pole C-curve MCB, 40 A, 50 kA

Where it fits — panel and environment

Snaps onto standard mounting rail or screws into the panel backplate. Ambient range -25 to +45 °C, storage down to -40 °C. Mount in any position; installation depth 92 mm. Tunnel terminals top and bottom simplify daisy-chaining busbars or looping out to downstream loads.

Mechanical and environmental robustness

Rated for 20 000 mechanical switching cycles. Withstands shock at 150 m/s² (11 ms half-sine) per IEC 60068-2-27 and vibration at 50 m/s² (25–150 Hz) and 60 m/s² at 35 Hz (4 s) per IEC 60068-2-6. Screw terminals torque to 2.5–3.5 N·m (22–31 lbf·in).

Frequently asked questions

Where can I buy 5SP9240-7KC47 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What is the breaking capacity of 5SP9240-7KC47?

50 kA at 400 V AC per IEC 60947-2. That is the high-fault rating that lets it hold up in industrial panels with high available fault current.

What conductor sizes does 5SP9240-7KC47 accept?

Solid and stranded conductors from 0.75 to 50 mm² (AWG 14 to 2). The tunnel terminals top and bottom accept that full range.
