ABB has the industry's most comprehensive range of time relays measuring and monitoring relays, interface relays and power supplies – helping you to source all critical components from a single global supplier. 

Limit Switches

Limit Switches LS2, LS3, LS4
ABB limit switches are an easy and reliable way to convert mechanical movements into electrical signals.

Time Relays
Time relays are available in three different ranges to cover every application.

CT-C time relays
The CT-C range combines higher value and performance at a lower cost by offering essential functions.
CT-D time relays
The CT-D range has a compact modular housing which is ideal for building applications and installation panels.
CT-S time relays
CT-S range high-performance time relays.

Measuring & Monitoring Relays

CM-Exx and CM-Sxx Single-phase monitoring relays
CM-Exx and CM-Sxx are the single-phase current and voltage monitoring relays that provide reliable monitoring of voltages and currents by using the TRMS measuring principle.
CM-MPx and CM-Pxx three-phase monitoring relays
The three-phase monitoring relays of the CM range guarantee reliable and continuous monitoring of a three-phase network as well as the trouble-free and economic operation of...
CM-UFx Grid feeding monitoring relays
The CM-UFx grid feeding monitoring relays monitor voltage and frequency according to the relevant standards for decentral energy generation.
