Why Choose the ETE XMS300P0S6 Class II Enclosed Safety/Isolating Transformer?
The ETE XMS300P0S6 is a high-capacity 300 VA single-phase Class II enclosed safety/isolating transformer designed to provide a dependable 24 V AC output from a nominal 110 V AC primary supply. Part of the ETE XMS stock control transformer range, it combines Class II electrical protection construction, an integral moulded housing and chassis mounting for integration into appropriately designed industrial electrical equipment.
The XMS300P0S6 features primary terminals marked 0/110V and secondary terminals marked 0/24V, providing a straightforward voltage transformation arrangement for compatible industrial control and auxiliary equipment. Its Class II construction uses a double-insulated or reinforced-insulated protection concept, while the integral moulded housing provides an enclosed transformer assembly. Unlike smaller XMS models offering alternative mounting arrangements, the XMS300P0S6 is specified for chassis mounting only.
With a rated apparent power of 300 VA, Class F insulation and dimensions of 126 × 136 × 127 mm, the ETE XMS300P0S6 offers substantial capacity for compatible 24 V AC control and auxiliary circuits. Weighing 5 kg, it is intended for secure installation onto a suitably supported chassis or mounting surface within industrial machinery, control panels and electrical assemblies.

Class II Enclosed 110 V to 24 V AC Transformer for Industrial Control Applications
The ETE XMS300P0S6 is designed for applications requiring a 24 V AC supply derived from a nominal 110 V AC input. Its primary terminals are marked 0/110V, while the secondary terminals are marked 0/24V. This straightforward input and output arrangement makes it suitable for compatible industrial control equipment, particularly where an available 110 V AC supply must be transformed to a lower AC control voltage.
A defining feature of the XMS300P0S6 is its Class II construction. Class II electrical equipment uses double or reinforced insulation as its protective measure, rather than relying on protective earthing of accessible conductive parts. This classification should not be confused with the transformer's separate Class F insulation specification, which describes the thermal classification of the insulation system. Both classifications are relevant to transformer selection but address different aspects of its electrical design.
The transformer features an integral moulded housing and is specified for chassis mounting only. This distinction is important when planning electrical cabinet layouts or replacing an existing transformer. The installation must provide a suitable chassis or mounting surface capable of supporting the transformer's 5 kg weight. DIN rail mounting is not an authorised mounting option in the supplied specification. The integral moulded housing is the stated enclosure reference; it does not independently establish an ingress protection rating or suitability for outdoor installation.
Its 300 VA rated apparent power provides capacity for one or more compatible 24 V AC loads, provided their combined operating and starting demands remain within the transformer's permitted limits. At a nominal 24 V output, 300 VA corresponds to approximately 12.5 A when calculated from apparent power divided by voltage. This is a theoretical sizing reference, not a separately stated manufacturer output current rating. Suitable load assessment should also consider any significant inrush current requirements of connected equipment.
Installation should be carried out by suitably qualified personnel in accordance with ETE's instructions and applicable electrical requirements. Appropriate primary and secondary circuit protection, conductor sizing, ventilation, chassis support and electrical clearances must be provided. The transformer's Class II protective construction must be preserved during installation, operation and maintenance.

What is the power rating of the ETE XMS300P0S6?
The transformer has a rated apparent power of 300 VA. Connected equipment must be selected so that its combined operating and starting requirements remain within the transformer's permitted ratings.
What primary input voltage does the XMS300P0S6 require?
The transformer has primary terminals marked 0/110V and is specified for a nominal 110 V AC primary input.
What secondary output voltage does the XMS300P0S6 provide?
The transformer has secondary terminals marked 0/24V and provides a nominal 24 V AC output.
What does Class II mean for the ETE XMS300P0S6?
Class II refers to an electrical protection concept based on double or reinforced insulation rather than reliance on protective earthing of accessible conductive parts. Installation must preserve the manufacturer's intended protective construction.
Is Class II the same as Class F insulation?
No. Class II describes the transformer's electrical protection construction, while Class F describes the thermal classification of its insulation system. The ETE XMS300P0S6 has both Class II construction and Class F insulation.
Can the ETE XMS300P0S6 be mounted on a DIN rail?
No. The supplied product specification states chassis mounting only. DIN rail mounting is not specified for the XMS300P0S6. The mounting arrangement must provide adequate mechanical support for the transformer's 5 kg weight.
Does the XMS300P0S6 have an enclosed housing?
Yes. The transformer is supplied with an integral moulded housing. This is the specified enclosure reference and should not be interpreted as a particular ingress protection rating.
What are the dimensions and weight of the ETE XMS300P0S6?
The transformer measures 126 × 136 × 127 mm (length × width × height) and weighs 5 kg.
What is the insulation class of the XMS300P0S6?
The ETE XMS300P0S6 has Class F insulation. This is its thermal insulation classification and is separate from its Class II electrical protection construction.
How much current can a 300 VA, 24 V transformer theoretically supply?
Dividing the 300 VA apparent power rating by the nominal 24 V secondary voltage gives approximately 12.5 A. This is a calculated sizing reference, not an independently stated manufacturer current rating. The actual connected load must comply with the manufacturer's operating limits.
A Practical Choice for Industrial Control Panel Builders and Engineers
The ETE XMS300P0S6 combines 300 VA capacity, a nominal 110 V AC primary input and a dedicated 24 V AC secondary output in a Class II enclosed safety/isolating transformer.
