The Siemens SITAS 4AM4842-5AT10-0FB1 is a 500 VA single-phase control transformer that steps down 400 V primary to 230 V secondary — with DIN rail mounting and cage-clamp terminals for the fastest possible panel installation. Snap it onto the DIN rail, push in the wires, done. With 2.17 A continuous output and 2000 VA short-term capacity, it reliably powers contactor coils, relays, and PLC power supplies in standardized control panels.

Key Features

• DIN rail mountable with cage-clamp terminals — snap-on installation and tool-free wiring for fastest panel assembly
• Adjustable primary voltage taps at 380/400/420 V (±5%) compensate for supply voltage variations
• 2000 VA short-term capacity (4× nominal) handles high inrush from contactor coils and relay banks
• Low inrush current design simplifies primary-side protection coordination
• Compact EI 120/72 core: 122 × 121 × 134 mm footprint
• 50/60 Hz dual-frequency operation for global industrial power compatibility
• IP00 open-type construction for enclosed panel or cabinet mounting

Technical Data

Applications

This DIN rail transformer is designed for supplying control circuits in standardized industrial control panels where rapid DIN rail installation and modular panel design are priorities. The cage-clamp terminals and snap-on mounting reduce panel assembly time, while the compact EI 120/72 footprint maximizes available DIN rail space. The ±5% adjustable primary taps provide adaptability for installations with fluctuating mains voltage, and the 2000 VA S6 rating handles contactor and relay inrush currents.
