Product details

The 50 kA breaking capacity per IEC 60947-2 at 400 V AC gives it the interrupting capability for industrial panelboards where fault currents are substantial; the same unit also carries a 15 kA DC rating per IEC 60947-2 and a 5 kA rating per UL 1077 and CSA C22.2 No. 235 for North American acceptance.

Rated for ambient temperatures from -40 °C to 75 °C, with derating above 45 °C: 6 A at 45 °C, 5.85 A at 50 °C, 5.69 A at 55 °C. Mounting position is any; depth behind the panel is 70 mm (76 mm overall). Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz.

The 5SY8606-8 is halogen-free and silicon-free, and is sealable for tamper-evident applications. The product designation per IEC 81346-2 and DIN EN 61346-2 is F.

Frequently asked questions

Where can I buy 5SY8606-8 and how is it quoted?

The 5SY8606-8 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of 5SY8606-8?

50 kA per IEC 60947-2 at 400 V AC, 15 kA per IEC 60947-2 at DC, and 5 kA per UL 1077 and CSA C22.2 No. 235.

Will 5SY8606-8 drop into a panel specified around 5SY7210-7CC?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint, but verify the tripping characteristic and rated current — the 5SY8606-8 is a D-curve 6 A unit, while the 5SY7210-7CC is a different variant. Panel cutout and busbar spacing are identical, but the protection curve and ampacity must match the circuit design.

What compliance documentation does Siemens provide for 5SY8606-8?

RoHS, REACH, IEC 60947-2, UL 1077, and CSA C22.2 No. 235 compliance is documented on the nameplate and in the accompanying declaration of conformity.
