2.4.6 Accessories and enclosures

Since manual motor starters combine the functions of multiple components, such as circuit-breakers, disconnect
switches, and overload relays, they are offered with many of the same types of accessories. Thus, the manual motor
starters can be extended with auxiliary contacts which can be connected either on the side or - especially to save
space - on the front. Also, undervoltage releases are available, and shunt releases complement the product range.
With the help of separately available adapters can the manual motor starter easily and quickly, build to a compact
starter combinations of motor protection switch and contactor.
