At 16 A it handles a 3.5 kW resistive load on 230 V single-phase per pole. The 10 kA IEC 60898-1 rating is the domestic breaker standard; the 20 kA IEC 60947-2 rating means it can also sit in an industrial distribution board with higher prospective fault current without derating.
Sealable for lockout/tagout. Operating temperature range -40 to 75 °C, with a derating curve above 35 °C (15.23 A at 40 °C, 14 A at 55 °C).
3-pole, B-curve, 16 A rated current. Breaking capacity: 10 kA per EN 60898-1 and 20 kA per IEC 60947-2. Operating temperature -40 to +75 °C.
Both are 3-pole B-curve 16 A MCBs with the same DIN-rail footprint, so mechanical fit is identical. The 5SY4316-6 carries a higher IEC 60947-2 breaking capacity (20 kA vs the 5SL's 10 kA), which gives more fault-current headroom. Wiring and terminal positions match.
The breaker is certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077. It is halogen-free and silicon-free. Expect CE, UKCA, and UL markings on the nameplate.
