Product Description

The Siemens 4AM3242-4TT10-0FA1 is a 63 VA SITAS 1:1 isolation transformer equipped with Cage-Clamp spring-loaded terminals, enabling fast, vibration-resistant wiring without the need for screwdrivers or periodic retightening. It provides full galvanic separation between two 230 V AC circuits while maintaining the same voltage level on both sides.

Why Cage-Clamp Terminals

Tool-free push-in wiring reduces panel assembly time and eliminates screw-tightening errors
Spring-loaded contact maintains consistent clamping force over the product lifetime, even under vibration
63 VA continuous power with 190 VA S6 short-time headroom for momentary overload conditions
230 V primary with ±5% taps (218/230/242 V) and 230 V secondary at 0.27 A rated current

Typical Use and Alternative

Used to create floating 230 V circuits that eliminate ground loops in distributed instrumentation or provide reinforced isolation for auxiliary equipment. Mounts via screws or DIN rail inside an enclosure. For the same electrical ratings with conventional screw-type terminals, the 4AM3242-4TT10-0FA0 variant is also available in the SITAS range.
