Product details

The 15 kA DC rating per IEC 60947-2 covers DC-side protection in rectified supplies. Under UL 1077 and CSA C22.2 No. 235 it holds a 5 kA interrupting rating — that's the number to use for North American supplementary protection listings.

Any mounting position is allowed. Combined terminals top and bottom simplify busbar and outgoing wiring. Neutral conductor switching is integrated — no separate neutral link needed.

Derate the 50 A rating at elevated temperatures: 48.95 A at 50 °C, 47.85 A at 55 °C. Halogen-free and silicon-free construction. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Suitability marked for mechanical engineering and industry.

Lockout & Touch Protection

The breaker is sealable — padlockable in the OFF position for positive isolation during maintenance. Touch protection is built in per the product feature. If it's not locked, it's not safe — this one accepts a lock.

Frequently asked questions

Where can I buy 5SY8650-7 and how do I get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.

Will 5SY8650-7 drop into a panel specified around 5SY7210-7CC without rewiring?

Both are 4-pole SENTRON MCBs on the same DIN-rail quick-assembly system, same 4 MW width. The 5SY8650-7 is a 50 A C-curve; the 5SY7210-7CC is a different rating. If the panel was wired for a 4-pole 50 A C-curve, it fits without rewiring. If the original callout was a lower ampacity, verify the load and upstream protection before swapping.

What is 5SY8650-7's listed depth?

76 mm overall depth, with a 70 mm installation depth behind the panel face.

What compliance documentation does Siemens provide for 5SY8650-7?

The breaker is halogen-free and silicon-free. It carries IEC 60947-2, UL 1077, and CSA C22.2 No. 235 ratings. RoHS and REACH declarations are standard Siemens documentation for the SENTRON line — request them with your RFQ.
