Product details

Siemens 5SY7602-8 — 4-pole D-curve MCB for industrial branch circuits

The Siemens 5SY7602-8 is a 4-pole (3P+N) miniature circuit breaker from the SENTRON series, sized at 4 modular width units (72 mm) for DIN-rail panels. Rated 2 A at 35 °C, it derates to 1.7 A at 60 °C, so the actual continuous load must be checked against the panel ambient temperature. The DC rating of 15 kA per IEC 60947-2 covers DC branch circuits, common in control power or battery-backed loads.

Integration — panel fit and wiring

The breaker is sealable for tamper-proof applications. Halogen-free and silicon-free construction avoids corrosive off-gassing in sealed enclosures or near sensitive contacts. Ambient humidity limits: max 95% at 55 °C, derating to 35% at 75 °C.

Frequently asked questions

Where can I buy 5SY7602-8?

The part 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 5SY7602-8?

15 kA per EN 60898 for general distribution, 50 kA per IEC 60947-2 for industrial duty, and 15 kA at DC per IEC 60947-2.

What does the D tripping characteristic mean?

The D curve trips at 10–20 times the rated current (2 A), so it handles high inrush from small motors, transformers, or solenoid banks without nuisance tripping.

What is the temperature derating for 5SY7602-8?

Rated 2 A at 35 °C, derated to 1.85 A at 45 °C, 1.8 A at 50 °C, 1.75 A at 55 °C, and 1.7 A at 60 °C. Ambient temperature inside the enclosure governs the actual continuous load.
