Circuit Breakers

Type CTI 25M, CTI 45MB

Circuit breakers for short circuit and overload protection of motor applications cover the current range 0.1 – 45 A (AC-3 rating). The product range is split in two product sizes. The smallest size is CTI 25M. It consists of 14 code numbers and covers the current range 0.1– 32 A. The bigger size is called CTI 45MB. It consists of two code numbers and covers the current range from 23 – 45 A.

The program is very exible and includes addon accessories such as auxiliary contacts, alarm contacts, voltage and under voltage trips, connection terminals and bus bars.

Features • Indication for magnetic trip (short circuiting)

• Overload protection and short circuit protection of motor installations

• Test function for thermal trip

• Manual reset function

• Indication for thermal trip

• Single phase protection (Dierential trip)

• Temperature compensated (-20 – 60 °C)

• Tripping class 10
