Product Description
The SITAS 4AM4642-4TN00-0EB0 is the DIN rail mount version of the 400VA 230V-to-24V control transformer, featuring cage-clamp spring-loaded terminals for tool-free, vibration-resistant wiring. Electrically identical to the 4TN00-0EA0 screw-mount variant.
Electrical Performance
Rated at 400VA continuous with a short-time power rating of 1,440VA (S6 duty). The EI 120/52 laminated core achieves approximately 91 percent efficiency. Primary taps at 218/230/242V accommodate mains voltage variation. Full galvanic isolation via II0 vector group.
Mechanical Design
Compact 122x121x114mm IP00 open-frame design. The 0EB0 variant differentiates with cage-clamp terminals and DIN rail mounting — reducing wiring time and enabling snap-on panel integration. Class B (130 C) insulation, rated for 40 C ambient.
Application
Suited for control panels where fast installation and maintenance are priorities. The DIN rail mount integrates directly into standard 35mm DIN rail enclosures, while cage-clamp terminals maintain reliable connections under vibration.
