Product details

Siemens 5SY4202-7-ZW08 — SENTRON 2-Pole MCB, C-Curve

The 2-module-width (36 mm) body snaps onto DIN rail and accepts any mounting position. At 400 V AC (multi-phase) the breaker clears fault currents up to 10 kA under EN 60898, and up to 35 kA under IEC 60947-2 — the higher figure matters when the panel SCCR requirement exceeds 10 kA. For DC circuits, it's rated 15 kA at 60 V (72 V max) per IEC 60947-2.

Panel Fit and Environmental Range

The quick-assembly fastening system clips onto the rail without tools — handy when you're populating a row of breakers. Ambient temperature range spans -40 °C to 75 °C, with humidity derating above 55 °C (95% RH to 55 °C, 55% to 70 °C, 35% to 75 °C).

This breaker carries dual certification: IEC/EN 60898-1 for residential-style MCB duty and IEC/EN 60947-2 for industrial use, plus UL 1077 / CSA C22.2 No.235 for supplementary protection in North America. Halogen-free and silicon-free construction simplifies disposal and avoids contamination in sensitive environments like semiconductor fabs or food processing lines.
