The SITAS 4AM5742-8JD40-0FA1 is a 1000VA single-phase control transformer with the widest primary tap range in the 4AM5742 series — six taps from 415V down to 215V — and dual 115V secondaries that can be series-connected for 230V (4.35A) or parallel-connected for 115V (8.70A). Cage-clamp terminals provide tool-free, vibration-resistant wiring for fast panel assembly.

Electrical Performance

Rated at 1,000VA continuous with a short-time power rating of 5,000VA (S6 duty). The EI 150/90 laminated core achieves approximately 93 percent efficiency. The six-tap primary handles a wide range of international grid voltages without requiring separate transformer models. III0 vector group with shielded isolation.

Mechanical Design

Compact 152x144x132mm IP00 open-frame construction for enclosure installation. The -0FA1 variant features cage-clamp spring-loaded terminals for maintenance-free, vibration-resistant connections. Screw-mount chassis. Class B (130 C) insulation system, rated for 40 C ambient. Weighs approximately 16 kg.

Application

Ideal for international machine builders who need one transformer model to cover control panels shipped to countries with different mains voltages — from 215V to 415V. The dual secondary adds flexibility for both 230V and 115V control circuit standards.
