The 3RA2130-4EA35-0NB3: The 32 A rating at both 480 V and 600 V tells you the current-limiting element is the overload relay, not the contactor's arc extinction — the contactor in this assembly (3RT2035-1NB30) is sized to clear the full motor locked-rotor current within the Class 10 window, provided the upstream short-circuit protection is coordinated per IEC 60947-4-1.
Panel integration and mounting constraints
Mounts via screw and snap-on to two parallel 35 mm DIN rails — the 274 mm height and 55 mm width fit a standard S2 feeder footprint, but the 150 mm depth plus 32 mm forward clearance and 50 mm upward clearance means the gland plate and door swing must accommodate the full envelope before you lay out the backplane. Screw-type terminals on the main current circuit — no spring-cage option on this variant, so factor in a torque screwdriver for the power connections and allow tool access above the terminals (50 mm upward clearance is the minimum for screwdriver swing). The supplied link module (3RA2931-1AA00) bridges the contactor and overload — it's pre-assembled, so the only field wiring is the incoming line, motor leads, and the 20-33 V control coil circuit.
Lifecycle and sourcing posture
The 20-33 V coil range covers 24 VDC nominal supplies with margin for brownout — common in control panels with a 24 VDC bus, provided the supply holds above 20 V under load.
