The Siemens 5SY6602-7 is a 4-pole (3P+N) SENTRON miniature circuit breaker with a C-curve tripping characteristic, rated at 2 A at 35 °C on AC supply.
Ratings that matter for fit
The 6 kA per EN 60898 is the residential/commercial rating; the higher IEC 60947-2 rating is what matters for machinery panels. Temperature derating is built in: at 45 °C the continuous current drops to 1.85 A, at 50 °C to 1.8 A, at 55 °C to 1.75 A — if the panel runs hot, you need to account for that or step up one frame size.
Mounting position is any — horizontal, vertical, upside down — no derating required. Sealable, halogen-free, silicon-free — relevant for food, pharma, or clean-room panels where outgassing or tamper-proofing is specified.
