Siemens Industrial Controls MT0250M Transformer

The Siemens MT0250M Class MT Control Transformer is a rugged, 250VA rated industrial solution designed for stepping down high-voltage feeds in demanding motor control environments. Built with a silicon steel-laminated core and high-quality copper magnet wire, this unit delivers superior voltage regulation and thermal efficiency. The primary dual-voltage input of 240/480 VAC and secondary output of 120/240 VAC make it highly versatile for domestic and international panel configurations. To ensure maximum reliability in hostile environments, the coils are epoxy encapsulated, sealing the internal components against moisture, dust, and industrial contaminants. This 1-phase transformer is engineered to handle high inrush VA demands without sacrificing secondary stability, meeting stringent UL and CSA standards. Integration is simplified via factory-mounted screw-type terminals and heavy-gauge steel mounting brackets, providing a secure, vibration-resistant panel mount installation for contractors managing complex HVACR or automation systems.

• Environmental Protection: The epoxy-encapsulated design ensures the 250VA transformer remains operational in high-moisture or dusty industrial settings.
• Superior Efficiency: Features a high-grade silicon steel core to minimize core losses and thermal rise during heavy duty cycles.
• Simplified Wiring: Includes secondary fuse clips and terminal jumpers for dual primary voltage configurations, saving critical panel space.
• Reliable Performance: Optimized to provide precise voltage regulation during magnetic device inrush, preventing contactor chatter or control failure.

What type of fuses should be used with the Siemens MT0250M?
It is standard practice to use time-delay fuses on the primary side to accommodate high inrush current without nuisance trips, while the secondary side can utilize fast-acting fuses for component protection.

Can this transformer be used for both 50Hz and 60Hz applications?
Yes, the Siemens industrial control transformer is dual-rated for 50/60 Hz, allowing for broad compatibility with various regional power grids.

Are jumpers included for the dual-voltage primary?
Yes, each unit is supplied with two jumper links to facilitate wiring for either 240V or 480V primary input voltages.
