Effective February 23, 2024, ITC is discontinuing its popular line of IEC-type AC contactors from 9 to 95A, known as NC1-…., as well as the relevant accessories (overload relays NR2-…, auxiliary contacts, etc…).
While a limited supply of these components will still be available for some time, we are pleased to introduce a new line of IEC contactors covering the range of 9 to 500A, available with both AC coils (24 to 600V) and with multi-voltage coils (‘wide-range’ 24-250 VAC/DC), equipped with up to 4 auxiliary contacts and certified cULus. All corresponding accessories are available for this new series. ITC has already in stock a limited quantity of the new contactors; orders for the old line will be accepted, subject to conditions and availability.
A new quick reference catalog ‘EC-2401 - Ex9C Contactors’ describing the new line (known as Ex9C) is available – download.

ITC is offering the new Ex9QR5 line of Soft Starters (Solid State Reduced Voltage Starters or SSRVs) from NOARK.
Soft starters offer ramping up the voltage applied to the windings of a three-phase motor during the start-up phase, in order to prevent the well-known detrimental electrical and mechanical effects which occur in case of a direct start (high in-rush current and starting torque, stress on mechanical components, etc...).
The Ex9QR5 devices offer several programmable modes of operation, plus a number of protection functions, including phase loss or unbalance, overload, over- and under-voltage, locked rotor, starter timing, and additional features.

Starting a 3-phase motor presents several problems, well known by designers and users of this type of equipment. Direct starting an AC motor will cause inrush current frequently higher than 5 times full-load current (FLA); the resulting high torque may produce mechanical stress on the equipment connected; and, last but not least, users may incur penalties from their Utility, due to consequences of the temporary high inrush current on the network.
The following is a compact and simplified exposition of the methods used to start a three-phase electric motors. The choice of these methods depends on the need to minimize the effects mentioned above – effects which are, in turn, depending also on the power rating of the motor.

Do you want to mount your device on DIN Rail?
If you need to mount on a standard 35mm DIN rail a device which is not equipped with a foot clip, ITC’s DINBASE is the solution. No drilling, no special tools!
DINBASE is a sturdy steel support measuring 92x28x11mm (3.6x1.1x0.4 in) which is mounted on any 35mm rail and fixed by a single screw. Equipment such as small transformers, definite-purpose contactors and, enclosures can then be fixed upon the same by using two sliding caged nuts (M6 is standard, M4 and M5 are available), or the existing holes (4mm) spaced maximum 76mm (2.99”).
