SCHELINGER A11-SR8-4P-063 4P 63A lastscheider

The SCHELINGER A11-SR8-4P-063 is a high-quality 4-pole isolator switch designed for reliable electrical isolation in industrial and commercial installations. Rated at 63A and 400V AC, this switch ensures safe disconnection of circuits for maintenance and emergency shutdown. Compliant with IEC/EN 60947-3, it offers robust performance with a rated impulse withstand voltage of 4 kV and a short-circuit making capacity of 3 kA.

Advantages

This isolator switch provides clear ON/OFF position indication, ensuring safe operation. Its compact 4-module (72 mm) design fits standard DIN rail (TH35) enclosures, saving space in distribution boards. With high electrical endurance (10,000 cycles) and mechanical endurance (20,000 cycles), it delivers long-lasting reliability. The front protection rating of IP40 and terminal protection of IP20 offer good resistance to dust and touch.
