Product details

Railway & industrial deployment

This MCB is specifically designed for railway applications, with a vibration resistance of ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz per IEC 60068-2-6 — critical for on-board panels subject to constant shock and vibration. The ambient temperature range of -40 °C to +75 °C covers both cold-soaked winter starts and hot summer traction compartments. Mounts in any position via the quick assembly system (snap-on DIN rail), occupying 3 modular width units (54 mm wide). The IP20 rating with connected conductors is standard for enclosed panel use; the sealable design allows lockout/tagout for maintenance isolation. Suitable for mechanical engineering and industry, with pollution degree 3 and overvoltage category III — meaning it can handle the transient voltages typical of industrial and railway power systems.
