REDLED Onesto Switch-Disconnector KCM-N 4P 63 A – IEC 60947-3, DIN Rail, 415 V

The REDLED Onesto KCM-N is a four-pole (4P) switch-disconnector (isolator) rated 63 A — a manual load-break switch for a distribution board, not an automatic circuit breaker. Its job is clean, visible isolation: throw it and the downstream circuit is fully and safely disconnected for maintenance, a machine change-over, or a main switch on a sub-board.

Built to IEC/EN 60947-1 and 60947-3, it switches its full 63 A rated current on load, withstands a 6 kV impulse and 500 V insulation voltage, and mounts on a standard 35 mm DIN rail. It carries no thermal or magnetic trip — pair it with MCBs or fuses for overload and short-circuit protection; the Onesto handles the isolation.

Key Features

• Four-pole (4P) switch-disconnector rated 63 A

Product Benefits

• Gives you a proper isolating main switch on a sub-board — safe to work downstream
• On-load rated, so you can switch it under current without damaging the contacts
• 4P switches all live conductors together including neutral
• Standard DIN format drops into any consumer unit or enclosure

Why You'll Love It

• Solid, deliberate throw — you can feel the contacts make and break, no vague middle position
• 63 A headroom covers most domestic and light-commercial sub-mains comfortably
• IEC 60947-3 rating means it behaves exactly as an electrician expects on inspection
