196 A at 40°C — the rating that sizes the starter
The 3RW4434-2BC36: That is the continuous motor full-load current it can handle in a standard 40°C panel. At 50°C the rating drops to 173 A; at 60°C it is 152 A. The operating frequency is 50/60 Hz — one unit works on either line frequency without a configuration change.
Inside-delta wiring and adjustable current limit
This starter supports inside-delta circuit wiring, which lets the soft starter handle a motor line current higher than its own rating by connecting the thyristors in the motor delta legs. For a given motor, inside-delta reduces the current through the starter by about 58% compared to standard in-line connection — useful when the motor FLA exceeds the starter's 196 A rating. The adjustable current limitation lets you set the starting current between 100% and about 400% of the motor FLA, depending on the ramp profile. Minimum load is 8% — it starts lightly loaded conveyors or pumps without the starter dropping out on undercurrent. Integrated motor overload protection and intrinsic device protection mean you can omit a separate overload relay in many panels. The display shows fault codes locally — no need to pull up a laptop for basic diagnostics.
Mounting, wiring, and panel fit
Dimensions are 200 mm high, 170 mm wide, 270 mm deep. Mounting is screw fixing with the unit oriented on a vertical surface; it can be rotated ±90° or tilted ±22.5° front-to-back. Clearance above the unit is 100 mm, below 75 mm, at the sides 5 mm — the side clearance is tight, so plan airflow accordingly. Main circuit connection accepts busbar or cable: stranded 25–120 mm², finely stranded 16–95 mm², or AWG 4–250 kcmil. Maximum motor cable length is 500 m — beyond that, reflected wave spikes may need a dV/dt filter. Pollution degree 3 per IEC 60947-4-2 means it is rated for conductive dust and condensation typical in industrial panels — not clean-room or sealed environments.
