EATON LSHU-E50/3-KL hoofdbeveiligingsschakelaar, 50 A, 3-polig, 230/400 V AC, uitschakelkarakteristiek E, selectief

Main line protection switch with selective tripping characteristic E, rated at 50 A and 3 poles for 230/400 V AC systems. This circuit breaker provides reliable protection for main distribution lines, ensuring high selectivity and short-circuit breaking capacity up to 25 kA. Its compact modular design allows DIN rail mounting, making it suitable for industrial and commercial electrical installations.

Advantages

The LSHU-E50/3-KL offers exceptional selectivity, preventing unnecessary downtime by isolating only the faulty circuit. With a rated current of 50 A and 3-pole configuration, it handles high loads while maintaining safety. The E characteristic ensures precise tripping for main line protection, and the 25 kA breaking capacity provides robust short-circuit protection. Screw terminals accommodate conductors up to 70 mm² rigid, ensuring secure connections.

Suitable for

• Main distribution boards in industrial facilities
