Product details

Rated operating voltage is 400 V AC (440 V max single- or multi-phase) and 60 V DC (72 V max). The 2-pole design switches both phases; neutral is not switched. Breaking capacity varies by standard: 6 kA under EN 60898-1, 30 kA under IEC 60947-2, 15 kA at DC per IEC 60947-2, and 5 kA per UL 1077. This gives flexibility for industrial panels that need the higher interrupting rating while still meeting residential/commercial code at the lower figure.

The quick-assembly fastening system and combined top/bottom terminals simplify wiring. Halogen-free and silicon-free construction. Suitable for mechanical engineering and industrial environments.
