Product Description
The 4AM2342‑4TN00‑0EA1 is a certified safety transformer for control systems. It provides safe galvanic isolation between the 230 V supply network and 24 V control circuits. The generous multi‑tap primary (242V/230V/218V) allows voltage adaptation without additional components – a real advantage when the supply voltage fluctuates or when installed in older facilities. Together with the vibration‑proof cage‑clamp terminals, this makes it a robust choice for machine and panel builders who value longevity and safety.
Safety & Compliance
- Certified as a safety isolating transformer according to EN 61558‑2‑6.
- cRUus recognized for the North American market.
- Insulation class B, protection class IP00.
Connection & Installation
- Cage‑clamp terminals provide secure, maintenance‑free connections resistant to vibration.
- Screw mounting using the EI 60/20 iron core's two fixing holes.
- Compact dimensions (62 × 78 × 79 mm) fit into tight control panels.
