Phoenix Contact Termitrab Complete surge protection range

The Phoenix Contact Termitrab Complete range features a 3.5 mm ultraslim and compact surge protection solution.

This will allow technicians to build smaller systems to protect analog and digital signals transmitted using MCR as well as gain valuable installation space for system planning and save money.

Further, the 3.5 mm devices are claimed to provide the highest density for system expansion on the DIN rail, and technicians can easily expand their systems to protect up to 572 MCR signals per metre.

The 3.5 mm arrester is available as a push-in model, while the 6.2 mm Termitrab arresters provide technicians with considerable choice. They can choose from versions with screw or push-in connections, knife disconnections, pluggable arrestors and Ex approval, to meet their individual requirements.

The 6.2 mm arrester models also feature an integrated status indicator that lets technicians see when the unit has reached its end of life and requires replacing.

Technicians can also choose to install the optional, low-cost, remote signalling module to remotely detect overloaded surge protective devices and maintain the integrity of their system. The module is easy to retrofit and does not require any programming or additional wiring. It uses a photoelectric barrier to monitor the status of up to 40 adjacent protective devices and a floating contact transmits the status to the control room. The devices meet SIL 3 and IEC 61508.

The Termitrab Complete range has over 130 models and includes the ultranarrow 3.5 mm, to simple, single-stage 6 mm surge protection units, right through to multistage devices. The range is suitable for 12, 24 and 48 V systems as well as RTD, Tc and serial communications. The portfolio of Termitrab Complete arresters is suitable for use in process technology, wind power, water and wastewater treatment, building services and infrastructure.
