Terminals accept solid conductors from 0.5 to 4 mm², or 2x (0.5 to 2.5 mm²) — fine for standard motor leads up to about 4 mm². The screw-type main current circuit is familiar to any panel builder; no special tooling needed. Shock resistance of 15g / 11 ms means it holds up on vibrating conveyor drives. Carries ATEX protection type PTB 06 ATEX 3001 Ex II (2) GD, so it's rated for use in potentially explosive atmospheres (Zone 2 gas, Zone 22 dust) when paired with an appropriate contactor. Surge voltage resistance is 6 kV, and burst immunity meets IEC 61000-4-4 severity level 3 — 2 kV on power ports, 1 kV on signal ports. That covers most industrial EMC environments without external filtering.","metaTitle":"Siemens 3RB2113-4NB0 SIRIUS solid-state overload relay, Clas","metaDescription":"Siemens 3RB2113-4NB0 SIRIUS solid-state overload relay, trip class 5E/10E/20E/30E adjustable, contactor mounting, 690 V AC-3 max, IP20 front.
