The short-time delayed G design (super resistant K) means the residual-current element tolerates brief leakage pulses from equipment like VFDs or UPS filters, reducing nuisance trips on sensitive circuits. Rated insulation voltage (Ui) is 264 V, surge voltage resistance is 4 kV, and overvoltage category III applies — this RCBO is designed for fixed-installation distribution boards, not portable equipment. Mounts in any position on DIN rail; supply top or bottom. Installation depth 70 mm, overall depth 77 mm. Width 36 mm (2 MW). Halogen-free and silicon-free.","metaTitle":"Siemens 5SU1354-6LB20 SENTRON RCBO, 20 A, 10 kA, Type B, 1P+","metaDescription":"Siemens SENTRON 5SU1354-6LB20 RCBO, 20 A rated, 10 kA breaking capacity (EN 60898), Type B characteristic, 1P+N, halogen-free.
