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)
