Products & services
CTF – Time relay with forcibly guided contacts
The CTF time relays are designed for safety-critical applications and provide reliable, hardware-based time control wherever PLC solutions are too complex and SIL relays are not required. They enable precise timing functions in control and signalling circuits and feature reliable contact technology with clear feedback on the switching status, supported by positively driven contacts for fault diagnosis. Thanks to their compact design, narrow mounting width and a wide time range from 40 ms to 80 h, they are also suitable for space-constrained applications.
CMA – Coupling module with manual control
The CMA coupling modules have been specially developed for use in modern building automation and industrial systems and enable reliable manual operation of individual function groups.

Cx – pluggable industrial relays
Modern relays are electromechanical masterpieces of the highest precision and, in various designs, perform a wide range of tasks across every conceivable industrial sector. Semiconductor technology (solid-state technology) enables the development of solid-state relays (SSRs), which, unlike electromechanical relays, contain no moving parts. Switching is purely electronic and therefore wear-free. ComatReleco develops products using both technologies and is a competent partner for all industrial applications involving relays.
MRS13R – Overcurrent Protection Relay
Overcurrent protection relays in combination with circuit breakers are used primarily when conventional safety solutions are not possible, such as in high-current and high-voltage systems or in railway technology. They prevent electrical devices and systems from being damaged or destroyed by the harmful effects of excessive current in the event of short circuits or overload conditions. In contrast to many other conventional overcurrent protection solutions, many parameters can be configured with the MRS13R. In conjunction with circuit breakers, currents in the kA range can be switched and, in comparison to fuses, the switching state of overcurrent protection relays is reversible when the cause of the fault has been eliminated.
MR – Monitoring relays
The MRM series devices have been developed for the reliable monitoring of AC and DC signals in single-phase and three-phase electrical systems. • Monitoring of various electrical parameters: voltage, current, power (AC/DC), frequency, phase sequence or power factor cosϕ • Suitable for use in low-voltage and extra-low-voltage installations thanks to a wide measurement range • Wide range of monitoring functions: signals when values exceed or fall below the adjustable threshold value or window range • Power supply: DC 12–48 V or AC 110–240 V
