Product details

Mounting and wiring in the panel

The 45 mm width means it occupies one standard modular device slot; plan for 165 mm depth behind the panel door for clearance on the screw terminals. Main circuit terminals are screw-type, accepting 0.5...4 mm² solid or 2x (0.5...2.5 mm²) stranded. That covers most motor feeder wiring up to 4 mm² without needing terminal adapters. Strip length and torque are standard for SIRIUS screw terminals — consistent with the rest of the line.

That covers unheated warehouses and truck-bed exposure in most climates without special handling. Vibration resistance tested to 4...5.8 Hz at 15 mm displacement, then 5.8...500 Hz at 20 m/s² for 10 cycles — standard for industrial machinery mounted on a panel near a motor or gearbox. Shock rated at 60 m/s² (6g) for 10 ms, three shocks per axis, so it holds up to fork truck drops during commissioning.

Frequently asked questions

What coil voltage does the 3RA6120-1AP32 accept?

The coil accepts 110...240 V AC/DC, covering both AC and DC control voltage standards with a single part number.

What wire sizes does the 3RA6120-1AP32 accept on the main circuit terminals?

Screw-type terminals accept 0.5...4 mm² solid or 2x (0.5...2.5 mm²) stranded.
