Product Positioning

The 3RA2328-8XB30-1AN2 is a SIRIUS 3RA23 series S0 size forward and reverse contactor combination with a coil voltage of 220V AC. It is suitable for installing forward and reverse circuits of 18.5kW motors in distribution panels with limited space.

Core Product Advantages and Features

S0 compact size

It is smaller than the S2/S3 and is suitable for installation in situations where the space of the distribution box is limited.

18.5kW switching capacity

Rated current 38A, corresponding to an operating level of approximately 18.5kW AC-3 motor at 400V.

220V AC coil power supply

The coil is rated at 220V and 50/60Hz, and can be directly used with common 220V control power supplies.

Integrated interlocking module

The 2NO auxiliary contacts and mechanical and electrical interlocks are pre-integrated, eliminating the need for additional interlock devices on site.
