Siemens Industrial Controls MT0075M Transformer

The Siemens MT0075M is a 75VA control power transformer engineered for precision power conversion in high-demand industrial and HVACR control circuits. Designed with a silicon steel-laminated core and copper magnet wire, this Class MT transformer minimizes core losses and mitigates voltage instability caused by high inrush currents. The primary voltage 240/480V and secondary voltage 120/240V configuration provides the dual-voltage flexibility required for complex panel builds and local control circuit isolation.

Built for the rigors of the field, the MT0075M features epoxy-encapsulated coils that provide a complete seal against moisture, dust, and industrial contaminants. For streamlined installation, it includes screw-type terminals with integrally molded barriers to prevent electrical creepage and slotted feet for universal mounting. This industrial control transformer is a reliable solution for providing stable 120V or 240V power to contactors, relays, and PLCs from a 480V source.

• Enhanced Durability: Epoxy encapsulation protects internal windings from humidity and debris in hostile mechanical rooms.
• High Efficiency: Silicon steel laminations optimize magnetic flux, reducing heat generation and operating costs.
• Superior Connectivity: Screw terminals with 1/4-inch thread depth prevent stripping and ensure low-loss electrical connections.
• Safety Standards: UL listed and CSA certified for compliance with North American electrical codes and domestic industrial standards.
• Inrush Handling: Specifically wound to maintain secondary voltage stability during the activation of heavy inductive loads.

What is the maximum amperage output of the Siemens MT0075M?
At a 75VA power rating, the MT0075M provides a maximum amperage of 0.625A at 120V or 0.312A at 240V, making it suitable for standard control circuit components.

Can this transformer be used for 50Hz and 60Hz applications?
Yes, the Siemens MT0075M is rated for 50/60Hz frequency, allowing for standard operation across different power grid standards without performance degradation.

Does the MT0075M include primary or secondary fusing?
This model features factory-mounted secondary fuse clips on most versions to save panel space and simplify wiring for secondary circuit protection.
