What the ratings mean for fit
The 5SU1344-7RC32: The 32 A rating at AC and C characteristic mean this RCBO handles moderate inrush loads like motor starters and lighting banks without nuisance tripping, while the 30 mA Type A residual protection catches pulsating DC fault currents from electronics and variable-speed drives — common in mixed-load panels. Breaking capacity is 10 kA per EN 60898 for residential/infrastructure duty and 15 kA per IEC 60947-2 for industrial installations — the higher figure gives headroom in high-fault panels without upsizing the device. Overvoltage Category III and Pollution Degree 2 confirm it is rated for fixed-installation distribution boards, not plug-in portable gear.
Panel integration and mounting
Snap-on DIN rail mount, any orientation. The 7-module width (126 mm) and 70 mm depth fit standard distribution board cutouts — verify gland plate clearance if retrofitting into a panel originally laid out for narrower single-function breakers. Supply can enter from top or bottom; IP20 rating applies only with connected conductors in an installed distribution board — not rated for wet or dust-exposed locations. Rated for 50 Hz AC supply only, with insulation voltage of 440 V and surge voltage resistance of 4 kV.
