The SITAS 4AM4342-8ED40-0FA0 is a 315VA single-phase control transformer with a high-range multi-tap primary (575/550/525V) stepping down to 230V for industrial control circuits. It is designed for installations where mains voltage can reach up to 575V, such as Canadian or heavy-industrial power networks.

Electrical Performance

The EI 105/60 laminated core delivers approximately 90% efficiency at full load. The short-time power rating of 1,120VA (S6 duty) provides over 3.5x headroom for high-inrush loads from contactors, relays, and solenoids. Full galvanic isolation between primary and secondary via II0 vector group.

Mechanical Design

Compact 107x111x120mm IP00 open-frame design for enclosure mounting with screw terminals. Class B (130 C) insulation system per IEC 60085, rated for 40 C ambient. Weighs approximately 3.6 kg.

Application

Suitable for machine tool control panels, HVAC control systems, and industrial automation where 230V control circuits must be supplied from high-line voltage mains up to 575V.
