Product Specifications

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.
