Siemens 4AM3 Series Panel Mount Transformer, 160VA Power, 230V Secondary Voltage - 4AM3842-5AT10-0FA0


This panel-mount transformer provides galvanic isolation and steps a three-phase supply-derived input to a single low-voltage output for control and auxiliary circuits in industrial installations. It is intended for DIN-rail or screw fixing and operates on standard mains frequencies, offering a Compact alternative to larger control transformers in automation and electrical distribution panels.

Features & Benefits


• 160 VA rated apparent power delivers consistent auxiliary supply
• 420V primary accommodates higher-line voltage applications
• 230V secondary rated output supports standard control equipment
• 50 to 60 Hz frequency range enables flexible deployment across grids
• Screw and tab termination simplifies field wiring and maintenance
• 0.86 efficiency reduces internal losses during continuous operation

Applications


• Suitable for supplying control circuits in PLC cabinets
• Ideal for isolating sensor and instrumentation supplies
• Used for retrofitting auxiliary power in motor control centres
• Can be used for powering relay and contactor coils in panels

What protective class and thermal rating apply to this device?


It is specified with thermal class B and an ambient operating temperature rating of 40 °C, suitable for typical indoor panel environments.

How is the unit mounted and connected within a control enclosure?


The transformer is designed for screws or DIN-rail fastening and accepts screw-type and tab terminals for both input and output connections.

What short-term performance can be expected under transient loading?


It has a short-term Vector power capability of 490 VA and a relative short-circuit voltage of 7.7% to withstand brief overloads.

Are there shielding windings or temperature monitoring fitted?


No shielding windings are fitted and it does not include built-in temperature or insulation monitoring functions.

What mechanical characteristics affect panel planning?


The construction uses an EI96/44 iron core and the device mass is 2.871 kg, assisting space and mounting considerations.
