The 5SU1624-2RC40: The D curve means it's built for loads with high inrush — think motor starters, small transformers, or discharge lighting where a B or C curve would nuisance-trip on startup. The 300 mA Type AC residual detects sinusoidal AC fault currents only; it's the standard choice for general distribution where no DC or pulsed DC fault components are expected. Two-pole configuration with 4-module width. Snaps onto a standard DIN rail.
Current production lifecycle stage. Quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
