Product details

Its dual-rated breaking capacity — 10 kA per EN 60898-1 and 20 kA per IEC 60947-2 at 400 V AC — means it handles fault currents up to the higher figure under industrial panel rules, while the lower EN rating applies for residential or commercial distribution boards where the standard governs.

C-curve and load compatibility

The 5SY4313-7 is rated for 400 V AC (440 V with multi-phase operation) and 60 V DC (72 V max), covering standard 3-phase panel voltages and some DC control circuits.

The 5SY4313-7 carries dual certification to IEC/EN 60898-1 and IEC/EN 60947-2, plus UL 1077 and CSA C22.2 No. 235 (5 kA at AC per UL/CSA). This means it qualifies for European distribution boards (EN 60898) and industrial panels (IEC 60947-2), as well as North American supplementary protection applications under UL 1077.
