The 5SY5406-7: Four modular-width units (72 mm wide) snap onto the standard DIN rail via the quick-assembly system; mounting position is any orientation. The 76 mm depth and 70 mm installation depth fit standard distribution boards. Terminals are combined at top and bottom, accepting AC or DC supply — observe DC polarity per the marking.
Lifecycle status is current — no end-of-life notice or last-time-buy window on record. The 5SY5406-7 is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
Rated for pollution degree 2, overvoltage category II. IP20 with connected conductors — suitable for enclosed distribution panels, not for wet or washdown environments. Halogen-free and silicon-free construction. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. The C-curve characteristic (tripping between 5× and 10× rated current) is standard for general-purpose motor and lighting circuits with moderate inrush. No neutral conductor switching — the neutral pole is a switched-neutral variant only if ordered as such; this code is a 4-pole MCB with all poles protected.
