CHT 112 Three-Phase Motor 2-Pole B3 (4 kW)
CHT 112 three-phase motor, 2-pole (about 3000 r/min at 50 Hz), B3 foot mounting — Chiaravalli's IEC frame 112 aluminium motors in the IE3 efficiency class, 4 kW. Aluminium casing, IP55, class F insulation, IC411 fan cooling, phase separator, Δ/Y 230/400 V 50 Hz, RAL 9022 grey. The dimension sheets give the frame 112 B3 mounting dimensions; the other mountings are the sibling cards one level up.
How to pick from the table: choose the power, then the efficiency class — IE3 from 0.75 kW up (we supply IE3 and above only from 0.75 kW; IE1 below that). The type letter is the motor's length designation within the frame. Voltage 400/690 V standard from frame 160 (other sizes on request); brake motors and Siemens motors available on request.

Product Information
Reading the table
Every row is one motor of this frame, pole count and mounting: the type letter (the catalogue's length code), the efficiency class, rated power, speed, rated torque and current at 400 V, with the weight last. Pick the power you need, then the efficiency class.
Mounting
This page is one mounting — B14 (face flange, our most common fit on gearboxes), B5 (large flange) or B3 (foot). The electrical data is the same across the three; the mounting dimensions are on the dimension sheets (B3 / B5 / B14 drawings and the frame table). The other mountings are the sibling cards one level up.
Efficiency classes
IE is the international efficiency grading for electric motors (IEC 60034-30-1). The higher the number, the less of the electricity you pay for is lost as heat for the same shaft power — so a lower running cost over the years the motor is in service. IE1 is standard efficiency, IE2 high efficiency, IE3 premium efficiency and IE4 super premium efficiency. Nusaf supplies IE3 and above only from 0.75 kW up — IE1 motors are listed below 0.75 kW only. The exact efficiency figure for each motor is in the Chiaravalli catalogue.
Fitting to a gearbox
The frame size is the IEC size the gearbox flange is specified by — a gearbox listed for "IEC 80" takes a frame 80 motor in B5 or B14.
