Phoenix 3031487 ST 6 Spring-Cage Feed-Through Terminal Block, 6 mm², 1000 V, 41 A, Grey

In industrial control panels, reliable and maintenance-free wiring is essential. The Phoenix 3031487 ST 6 spring-cage feed-through terminal block solves this by providing a secure, vibration-proof connection for conductors up to 6 mm². Its tool-free spring-cage technology speeds up installation while ensuring a constant contact force, even in harsh environments. This terminal block is ideal for distributing power and signals in automation systems, machine building, and electrical installations.

Who is it for

This terminal block is designed for electrical engineers, panel builders, and maintenance technicians who need a compact, high-current connection point on standard DIN rails. It suits applications requiring frequent wiring changes or where space is limited, such as control cabinets, motor control centers, and distribution boards.

Main features

• Spring-cage connection: tool-free, vibration-proof, and maintenance-free.
• High current rating: 41 A nominal current for demanding circuits.
• Wide conductor range: accepts solid conductors from 0.2 to 10 mm² and flexible conductors from 0.2 to 6 mm².
