## Overview

The Siemens MT0300A Industrial Power Transformer delivers a robust 300 VA rating, efficiently stepping down multiple primary voltages to stable secondary voltages (120/115/110 V). Featuring a silicon steel-laminated core and copper magnet wire, it maximizes efficiency while minimizing inrush current impact. Its epoxy-encapsulated coils resist moisture, dust, and industrial contaminants, ensuring durability in demanding environments. Built-in fuse clips streamline installation, saving time and space. UL listed and CSA certified, this transformer is engineered for reliable industrial control and machine tool power transformation.

## Description

his Siemens MT0300A industrial power transformer has a 300 VA power rating, a voltage letter designation of A, and reduces 240 x 480, 230 x 460, or 220 x 440 V (primary voltage) to 120/115/110 V (secondary voltage). A silicon steel-laminated core and copper magnet wire increase transformer efficiency, which decreases the destabilizing effect of inrush current on secondary voltage. Epoxy-encapsulated transformer coils resist moisture, dust, and industrial contaminants, and built-in terminals and barriers resist breakage. Steel mounting brackets provide stable mounting and slotted mounting feet make installation easier. The thermal insulation class for this transformer is 105 degrees C with a 55 degree C (131 degrees F) temperature rise. This power transformer is Underwriters Laboratories (UL) listed and CSA International certified, and is suitable for use in transforming electrical power for machine tools and industrial control circuits.

## Features

- Reduces 240 x 480, 230 x 460, or 220 x 440 V (primary voltage) to 120/115/110 V (secondary voltage)
- Rated up to 300 VA
- Silicon steel-laminated core and copper magnet wire for increased transformer efficiency
- Epoxy-encapsulated to resist moisture, dust, and industrial contaminants
- Built-in fuse clips on secondary side save panel space and wiring time because they do not have to be manually installed in the field
- Fuse Block Shown in Image is Purchased Separately

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good purchase
*by C***L on May 15, 2025*

Very good

### ⭐⭐⭐⭐ Wiring up this transformer
*by K***R on July 17, 2025*

Easy to wire up for my step-down application. Terminal lugs are a little narrow for "yellow" fork terminals.

### ⭐⭐⭐⭐⭐ Be sure this xfmr is properly sized for your application
*by V***E on April 18, 2025*

Excellent quality, as suspected
