Product details

The 5SY4332-7: Rated to IEC / EN 60898-1 and IEC / EN 60947-2, plus UL 1077. The dual rating means it qualifies for both residential-distribution (60898-1) and industrial-panel (60947-2) applications — the 20 kA figure under 60947-2 is the one to use for SCCR calculations in industrial control panels. Also carries CSA C22.2 No. 235. Halogen-free and silicon-free construction suits clean-room or sensitive environments.

Mounting position any. Sealable for tamper-proof installations.

Environmental and operating conditions

Humidity influence: max 95% at 55 °C, derating to 55% at 70 °C, 35% at 75 °C. Frequency 50/60 Hz. Suitable for mechanical engineering and industry.
