D-curve and load compatibility
The D characteristic (10–20× In magnetic trip) is the right choice for loads with a high starting surge — think conveyors, compressors, or large contactor coils — where a C-curve would nuisance-trip on inrush. At 63 A per pole, this breaker handles a 3-phase motor group or a heavy resistive bank without derating the frame.
Panel fit and environmental tolerance
Width is 72 mm (4 modular width units).
Sealable terminals allow the panel builder to lock the cover after commissioning, preventing unauthorized tampering. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) means it holds up on a machine-mounted sub-panel next to a press or conveyor drive.
