The ETE XMS300P5S6 is a 300 VA single-phase Class II enclosed safety/isolating transformer designed to provide a nominal 24 V AC secondary supply from a 415 V AC primary input. Part of the ETE XMS transformer series, it combines Class II electrical construction, an integral moulded housing and chassis mounting for industrial control panels, machinery and automation equipment.
Featuring 0/415 V primary terminals and 0/24 V secondary terminals, the XMS300P5S6 provides dedicated AC voltage transformation for compatible low-voltage industrial control circuits. Its Class II construction incorporates protective insulation arrangements, while its safety/isolating transformer design provides electrical separation between the primary and secondary circuits. This makes it a practical choice for installations requiring an enclosed transformer with a defined 415 V to 24 V AC voltage configuration.
The XMS300P5S6 is specified for chassis mounting only, allowing installation on a suitably supported equipment mounting surface. With Class F insulation, dimensions of 126 × 136 × 127 mm and a weight of 5 kg, it offers electrical panel builders, OEM machinery manufacturers and maintenance engineers a practical solution for supplying compatible 24 V AC control equipment.
The ETE XMS300P5S6 provides a straightforward method of transforming a nominal 415 V AC primary supply into a 24 V AC secondary supply. Its 300 VA rated capacity makes it suitable for compatible industrial control equipment where the combined apparent power demand remains within the transformer's rating. Typical loads may include AC control relays, contactor coils, signalling devices and other electrical equipment designed for 24 V AC operation.
A key feature of the XMS300P5S6 is its Class II electrical construction. Class II equipment incorporates protective insulation arrangements designed to provide protection against electric shock without relying on a protective earth connection for its protective insulation system. The transformer's safety/isolating designation provides electrical separation between the primary and secondary circuits, supporting appropriately engineered low-voltage control power installations. Class II electrical construction is distinct from the transformer's Class F thermal insulation rating.
The integral moulded housing provides an enclosed transformer format, while the specified chassis-only mounting arrangement allows the unit to be installed on a suitable equipment mounting surface. Unlike smaller XMS models that may offer DIN rail installation, the XMS300P5S6 must be chassis mounted. The mounting surface and fixings should be suitable for its 5 kg weight and the conditions of the installation.
At its rated capacity, the calculated nominal secondary current is approximately 12.5 A at 24 V AC. This figure is derived from the 300 VA rating and nominal output voltage rather than a separately verified manufacturer current rating. The calculated ideal primary current is approximately 0.72 A at 415 V AC, excluding transformer losses and magnetising current. Suitable primary and secondary circuit protection, conductor sizing, ventilation and electrical clearances remain essential for dependable operation.
When selecting a transformer for control circuits containing contactors, solenoids or other inductive devices, both the continuous load and any short-duration inrush demand should be considered. The transformer's 300 VA rating alone does not establish its permissible short-duration inrush capability, so the complete load profile should be checked against the manufacturer's installation and application guidance.

The ETE XMS300P5S6 is a 300 VA single-phase Class II enclosed safety/isolating transformer used to provide a nominal 24 V AC supply from a 415 V AC primary input for compatible industrial control circuits, electrical panels and automation equipment.
The transformer has a rated apparent power of 300 VA (0.3 kVA). The combined apparent power demand of connected equipment should remain within the transformer's specified rating.
The transformer features 0/415 V primary terminals and is designed for a nominal 415 V AC primary supply.
The transformer features 0/24 V secondary terminals and provides a nominal 24 V AC output when connected to its specified primary supply.
Class II construction means the transformer incorporates protective insulation arrangements designed to provide protection against electric shock without relying on a protective earth connection for its protective insulation system. Correct installation and suitable circuit protection remain essential.
Yes. The XMS300P5S6 is specified as a Class II enclosed safety/isolating transformer. It provides electrical separation between the primary and secondary circuits for compatible applications, subject to correct installation and the requirements of the complete electrical system.
No. The ETE XMS300P5S6 is specified for chassis mounting only. DIN rail mounting is not a stated mounting option for this model.
The transformer must be chassis mounted on an appropriate equipment mounting surface. The mounting arrangement and fixings should support its 5 kg weight and meet the manufacturer's installation requirements.
Based on its 300 VA rating and nominal 24 V AC output, the calculated secondary current is approximately 12.5 A. This is a calculated value rather than a separately verified manufacturer current rating, and actual loading must comply with the manufacturer's requirements.
The transformer uses Class F insulation, providing a defined thermal insulation classification. This is separate from its Class II electrical construction.
The transformer measures 126 × 136 × 127 mm (L × W × H) and weighs 5 kg. These dimensions and its weight should be considered when planning the chassis mounting arrangement.
Yes. The XMS300P5S6 is supplied with an integral moulded housing. Depending on the installation environment, the overall electrical assembly may still require an additional protective cabinet or enclosure.
Yes, provided the connected devices are compatible with a 24 V AC supply and their combined apparent power demand is within the transformer's 300 VA rating. Any simultaneous inrush loads and other application-specific requirements should also be considered.
Installation should account for the specified 415 V AC primary supply, 24 V AC secondary output, 300 VA capacity, suitable circuit protection, conductor sizing, ventilation and the chassis-only mounting requirement. The mounting arrangement must support the transformer's 5 kg weight, and all connections should follow the manufacturer's instructions.
