The unit is instantaneous (no short-time delay), mounts on DIN rail, and occupies 3 width units. Type A detection means it responds to both sinusoidal AC residual currents and pulsed DC residual currents — a requirement for circuits with single-phase rectifiers, switching power supplies, or variable-speed drives. The 500 mA sensitivity is a higher threshold than standard 30 mA personal-protection RCDs; this unit is sized for equipment protection or fire prevention on circuits where nuisance tripping from leakage is a concern. The 63 A rating at 40 °C and 45 °C holds at 58.59 A, then derates to 56.7 A at 50 °C, 54.81 A at 55 °C, 53.55 A at 60 °C, 52.29 A at 65 °C, and 50.4 A at 70 °C.
