Circuit breakers / Manual motor starters

Type CTI 15

Circuit breakers/Manual motor starters CTI 15 cover the power ranges 0.09 – 7.5 kW

This product range is modular, flexible, and offers a large selection of clip-on auxiliary functions and accessories: auxiliary contact blocks, shunt releases, connection terminal, bus bars and enclosures.

Features	•	Short-circuit protection:
		An advanced and fast reacting contact system
		with arc-control devices give CTI high
		short-circuit break capability which makes
		them very suitable for the protection of
		electrical panels.
	•	Indicating functions:
		–– condition (ON or OFF)

•Supply isolation:

––operation switch (manual motor starter)

––isolation switch (with locking device)

––emergency stop switch (with undervoltage trip)

Max. motor load

AC-2 and AC-3 operation

The table contains kW values of rated motor sizes according to IEC 60072 which fits to the current range of the circuit breaker.

Sometimes more than one rated current fits to the range. In such cases both values are given and they are valid for AC-2 as well as for AC-3.
