CHT 315 Cast Iron Three-Phase Motor 4-Pole (110–200 kW)
CHT 315 cast iron three-phase motor, 4-pole (about 1500 r/min at 50 Hz) — Chiaravalli's IEC frame 315 cast iron motors in the IE3 / IE4 efficiency classes, 110–200 kW. Cast iron casing, IP54, class F insulation, IC411 fan cooling, Δ/Y 400/690 V 50 Hz. Mounting B3 (foot), B5 (flange) or B35 (foot and flange): pick it in the table's Mounting filter; the dimension sheets give the frame 315 mounting dimensions per efficiency class.
How to pick from the table: choose the power, the efficiency class — IE3 or IE4 (we supply IE3 and above only from 0.75 kW up; IE4 where the energy saving pays) — and the mounting. The type letter is the motor's length designation within the frame. Forced-cooling fan kits for inverter duty are available for every frame (catalogue p8).

Product Information
Reading the table
Every row is one motor of this frame and pole count: the mounting, the type letter (the catalogue's length code), the efficiency class, rated power, speed, rated torque, current at 400 V, efficiency and power factor. "Show starting and part-load data" adds the starting torque and current ratios (Ms/Mn, Mmax/Mn, Is/In), the rotor inertia J0 and, for IE3 / IE4 motors, the efficiency at 75 % and 50 % load.
Mounting
The table opens on B3 (foot). Switch the Mounting filter to B5 (flange) or B35 (foot and flange); the electrical data is the same, the mounting dimensions are on the dimension sheets per efficiency class.
Efficiency classes
From January 2017 the EU regulation (CE) 640/2009 requires motors of 0.75 to 375 kW with 2, 4 or 6 poles sold in the European market to be at least IE3. Nusaf supplies IE3 and above only from 0.75 kW up — IE1 motors are listed below 0.75 kW only. Efficiency figures follow IEC 60034-30 / 60034-2-1.
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.

- Cast iron casing
