SCHELINGER A11-SR8-1P-063 1-Pole 63A Isolator Switch, DIN Rail Mount, 230/400V AC

For installations where a robust, single-pole disconnection point is non-negotiable, the SCHELINGER A11-SR8-1P-063 stands apart from typical modular isolators. It combines a full 63 A rated current with a compact 1-module DIN rail footprint, making it a practical choice for both residential distribution boards and commercial control panels. Unlike many alternatives that compromise on terminal capacity, this switch accepts conductors up to 25 mm², ensuring secure connections even in demanding wiring scenarios.

Highlights

• Rated current of 63 A with 1-pole switching for single-phase isolation.
• Wide rated voltage range of 230/400 V AC, suitable for standard mains and three-phase auxiliary circuits.
• High insulation voltage of 500 V and impulse withstand of 4 kV for reliable performance.
• Compact 1-module width (18 mm) saves valuable DIN rail space.
• Terminal capacity up to 25 mm² accommodates thick conductors without ferrules.
• Mechanical endurance of 10,000 operations ensures long service life.

In daily use

Installation is straightforward: the switch snaps onto a standard TH35 DIN rail and offers clear ON/OFF indication. The front face provides IP40 protection, while terminals are rated IP20, making it safe for use inside distribution enclosures. Electricians will appreciate the generous wiring space and the ability to use either flexible or rigid conductors from 1 mm² to 25 mm². The operating temperature range of -25°C to +50°C allows deployment in unheated garages, basements, or outdoor kiosks with appropriate enclosure protection.
