The short-time delayed G and super resistant K design provides selectivity against nuisance tripping from transient leakage or short-duration ground faults, which is useful in distribution boards feeding multiple downstream RCBOs. It can be installed in any position, and the supply cord can enter from either top or bottom, which simplifies panel layout. The IP20 rating is typical for enclosed distribution boards — the protection is complete once the board cover is fitted and conductors are connected.
The RCBO is rated for a full 32 A at 30 °C ambient, but the current must be derated as the enclosure temperature rises: 30.4 A at 40 °C, 29.76 A at 45 °C, 28.8 A at 50 °C, 27.84 A at 55 °C, 27.2 A at 60 °C, 25.92 A at 65 °C, and 24.64 A at 70 °C. In a crowded panel with multiple breakers, the effective load current may need to be reduced — plan the thermal budget accordingly.
The 5SU1354-7LB32 is halogen-free and silicon-free, meeting material restrictions common in clean manufacturing environments. It carries the standard SENTRON approvals (CE, UKCA, EAC, and IEC/EN 60898 certification for the 10 kA breaking capacity). The product designation per DIN EN 61346-2 and DIN EN 81346-2 is F. For compliance documentation (RoHS, REACH, UL), the manufacturer provides declarations and certificates on request — these are typically included with the shipment or available through the distributor.
