Product details

Integrated motor starting for S0 load feeders

The 3RA2120-1GA24-0AP6 is a SIRIUS non-fused direct starter combining a 3RT2024-1AP60 contactor and a thermal bimetallic overload relay in a single S0-size package, pre-assembled with the 3RA2921-1AA00 link module.

Mounting and panel integration

Vertical mounting position only; clearance requirements are 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, and 0 mm backwards — plan the enclosure depth and gland plate accordingly.

Thermal and environmental limits

Operates from -20 to +60 °C with pollution degree 3 (conductive or dry non-conductive pollution becoming conductive) — suitable for industrial control panels without climate control, though the thermal overload setting must be adjusted for ambient temperature above 40 °C per the derating curve. Storage range -50 to +80 °C and transport range -55 to +80 °C cover cold warehouses and unheated freight.

Frequently asked questions

What are the key ratings for 3RA2120-1GA24-0AP6?

AC-3 rated voltage 690 V maximum, Class 10 thermal overload, S0 size.

What clearance is needed around 3RA2120-1GA24-0AP6 in a panel?

30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, and 0 mm backwards. The starter must be mounted vertically.
