Product details

The Siemens 5SY8215-7 is a 2-pole SENTRON miniature circuit breaker with a C tripping characteristic, rated 1.6 A at 440 V AC for multi-phase operation.

Thermal derating and environment

Rated 1.6 A at 45 °C, the breaker derates to 1.56 A at 50 °C and 1.52 A at 55 °C — a 5 % drop from the 45 °C baseline by 55 °C.

Breaking capacity is rated 70 kA per IEC 60947-2, 15 kA DC per the same standard, and 5 kA per UL 1077 / CSA C22.2 No. 235. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) confirms it holds up on machinery or in transport applications.

Frequently asked questions

What is the closest functional second-source for 5SY8215-7?

The closest peer in the SENTRON family is the 5SY4140-7, which shares the same 2-pole C-curve form factor but is rated 40 A — a different current class. The 5SY8215-7 at 1.6 A fills the low-current branch protection slot that the 5SY4140-7 does not cover. They are not drop-in substitutes; the 5SY8215-7 is the correct part for a 1.6 A BOM line.

Will 5SY8215-7 drop into a panel specified around 5SY4140-7 without rewiring?

Both are 2-pole, 36 mm wide SENTRON MCBs that clip onto the same DIN rail. The physical footprint is identical, so the 5SY8215-7 fits the same panel slot. However, the 5SY4140-7 is a 40 A breaker; replacing it with a 1.6 A unit would require rewiring the branch circuit to match the lower rating. For a new 1.6 A position, the 5SY8215-7 drops in without mechanical modification.

What compliance documentation does Siemens provide for 5SY8215-7?

The breaker carries ratings per IEC 60947-2, UL 1077, and CSA C22.2 No. 235. It is halogen-free and silicon-free, which supports RoHS/REACH compliance declarations. Standard documentation includes the declaration of conformity and the product datasheet.

Where can I buy 5SY8215-7?

The 5SY8215-7 is sourced to order against an RFQ through independent industrial-automation distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.
