Product details

It carries a 10 kA interrupting capacity per IEC/EN 60898-2 and UL1077, and 15 kA per IEC 60947-2 for DC faults. The 18 mm width (1 modular unit) snaps onto a DIN rail — standard panel fit for a 1P branch circuit.

C-curve and interrupting capacity

Panel integration

Snap-on DIN rail mount, any position. 18 mm width (1 MW) leaves room for adjacent breakers in a multi-pole assembly. Combined top and bottom terminals simplify daisy-chaining. Halogen-free and silicon-free construction for sensitive environments like medical or food processing.

Environmental and vibration resistance

Rated for ambient -40 °C to 75 °C, with humidity limits per temperature band (95% at 55 °C, 55% at 70 °C, 35% at 75 °C). Vibration tested per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — suitable for installation near rotating machinery or in mobile equipment.

Frequently asked questions

Where can I buy 5SY5106-7?

The 5SY5106-7 is available to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 5SY5106-7?

The 5SY4140-7 is a 1-pole C-curve MCB from the same SENTRON family, but it carries a 6 kA interrupting capacity (versus 10 kA for the 5SY5106-7). The 5SY5106-7 offers higher fault current handling and a wider DC voltage rating. Verify the interrupting capacity requirement before substituting.

What compliance documentation does Siemens provide for 5SY5106-7?

The 5SY5106-7 is certified to IEC/EN 60898-2 and UL1077. It is halogen-free and silicon-free. RoHS and REACH declarations are available from Siemens upon request.

Will 5SY5106-7 drop into a panel specified around 5SY4140-7 without rewiring?

Yes, both are 1-pole, 18 mm wide (1 MW) with the same DIN-rail footprint and combined top/bottom terminals. No rewiring needed for the panel layout — but verify the interrupting capacity requirement: 5SY4140-7 is 6 kA, 5SY5106-7 is 10 kA.
