It breaks fault currents up to 4.5 kA per EN 60898 and 6 kA per IEC 60947-2, with a UL 1077/CSA rating of 5 kA. The 18 mm width (1 MW) snaps onto standard DIN rail — quick assembly system — and accepts solid or stranded conductors from 0.75 to 35 mm² at the combined top/bottom terminals.
The housing is IP20 with connected conductors, rated for ambient temperatures from -25 to +55 °C operating, -40 to +75 °C storage. Sealable, halogen-free, and silicon-free construction suits food, pharma, or clean-room panels where outgassing matters.
Compared to the 5SY3132-6 (a 32 A C-curve sibling in the same 5SY3 family), the 5SY3102-7 shares the same 18 mm width, terminal range, and breaking capacities — the only difference is the 2 A rating. It drops into the same panel footprint without rewiring the busbar or DIN rail layout.
