Phoenix Contact MTRS485 Rail Mount RS-485 Surge Protection
The PHOENIX CONTACT MT-RS485 surge protection device is a critical component for safeguarding RS-485 communication lines from damaging voltage surges. Designed for rail mounting on NS 35/7.5, this module provides robust protection against line-to-line and line-to-ground surges, ensuring the longevity and reliability of connected equipment. Its compact design (77.5mm height, 47.6mm width, 54.9mm depth) makes it suitable for a wide range of industrial applications where RS-485 communication is essential, such as industrial automation, building management systems, and remote monitoring devices. The MT-RS485 offers surge protection with nominal discharge currents up to 10kA, minimizing downtime and maintenance costs.
