Why Choose the ETE XMS250P5S4 Class II Safety/Isolating Transformer?
The ETE XMS250P5S4 is a high-quality 250 VA single-phase Class II enclosed safety/isolating transformer designed to provide reliable electrical isolation and a 110 V AC secondary supply for industrial control circuits, electrical panels and automation equipment. As part of the ETE XMS Class II transformer series, it combines double-insulated construction, protected terminals and robust enclosure design for dependable operation in industrial electrical installations.
Manufactured by Eastern Transformers & Equipment (ETE), this transformer features an integral flame-retardant moulded housing with IP20 touch-proof terminals. Its Class II construction provides protective insulation without requiring a protective earth connection. The XMS series is designed to EN 61558-2-4 and EN 61558-2-6, with Class F insulation for reliable thermal performance.
With a rated capacity of 250 VA, a single-phase 415 V AC primary input and a 110 V AC secondary output, the XMS250P5S4 is suitable for powering compatible industrial control equipment. Its enclosed construction, measuring 126 × 136 × 127 mm, and chassis-only mounting arrangement make it suitable for secure installation within electrical control cabinets and machinery panels.

Safety and isolating transformers provide electrical separation between primary and secondary circuits through transformer insulation. The ETE XMS250P5S4 converts a nominal 415 V AC single-phase supply into a 110 V AC secondary output, providing an isolated supply for appropriately rated industrial control circuits and electrical equipment.
The XMS series uses Class II construction with an integral moulded enclosure, eliminating the requirement for a protective earth connection to the transformer itself. Its IP20 touch-proof terminals, Class F insulation and chassis-mounted design make the XMS250P5S4 practical for use in industrial control cabinets, machinery panels and electrical equipment assemblies where dependable 110 V AC control power is required.
Typical Applications
- Industrial electrical control panels requiring an isolated 110 V AC supply.
- Machinery control circuits supplied from 415 V AC systems.
- 110 V AC contactor, relay and control device circuits within the transformer rating.
- Industrial automation and machine control equipment.
- Electrical installations requiring Class II transformer construction.
- Building services and HVAC control systems.
- 110 V AC signalling and indication circuits.
- OEM electrical assemblies and chassis-mounted control equipment.
