Thermistor motor protection relays in new housing
The thermistor motor protection relays of the CM-MSS range monitor the winding temperature
of motors which have PTC temperature sensors installed. These sensors are incorporated in
the motor windings thus measuring the motor heat directly. This direct temperature measure-
ment enables the thermistor motor protection relays to evaluate various motor conditions such
as overheating, overload and insufficient cooling. Depending on the product also the ATEX
approval is available for the use in hazardous areas.
The new housing provides two different connection terminals: The proven double-chamber
cage connection terminals and the Easy Connect Technology with Push-in terminals.

CR-S Range pluggable small interface relays
The pluggable interface relays of the CR-S Range are used for electrical isolation, amplifica-
tion and signal matching between the electronic controlling, e.g. PLC, iPC or field bus systems
and the sensor / actuator level. The CR-S Range combines the flexibility of a modular system
and the ability of switching high currents on a small footprint thus can be used in applications
where space saving is essential.

Universal Motor Controller UMC100.3 now available
The intelligent ABB Motor Controllers for motor protection, motor control, fieldbus and Eth-
ernet communication and fault diagnosis. Due to the benefits it provides, the UMC is used
worldwide in many segments and in Projects with several thousand motor controllers. Beside
the proven UMC100 the new UMC100.3 offers even more capabilities like 24 V DC or
110-220 V AC/DC supply voltage and fieldbus communication interfaces.

Grid feeding monitoring relays from the CM-UFD.Mx range
The multifunctional grid feeding monitoring relays of the CM-UFD range are designed to moni-
tor several grid parameters when feeding energy into the public grid. The intention is to trip a
section switch which is connected between the distributed generation and the public grid in
order to disconnect the distributed generation in case of problems (e.g. unstable grid), faults or
maintenance on the grid. Different monitoring functions such as 10-minutes average value, real
time over- and undervoltage as well as over- and underfrequency are configurable via the front
face display.
