Motor Protection MCCB with Flat Derating to 70 °C
Breaking capacity is substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
Panel Fit and Auxiliary Contact Configuration
The 105 mm width is standard for a 3-pole 63 A frame in the 3VA series — it occupies three 35 mm DIN module positions if panel-mounted, or bolts directly into a mounting plate. Depth of 86 mm leaves clearance behind the panel for wiring and the auxiliary contact block.
Protection and Release Features
Includes an undervoltage release and phase failure detection as standard — both critical for motor protection applications where a phase loss can single-phase a motor and cause winding damage.
