Single-phase transformer PTM 250 230/24V IP21 for DIN rail TH-35 in enclosure 16024-9928

Single-phase transformer PTM 250 is a solid solution for powering devices requiring a safe voltage of 24V. Designed for mounting on a standard DIN TH-35 rail, it is suitable for both professional and home installations. Its housing provides protection against touch and environmental influences, and its construction guarantees reliable operation.

This Breve-Tufvassons transformer with a power of 250 VA is ideal for applications where a stable and safe voltage reduction from 230V to 24V is required. Designed as a safety transformer, it protects users and devices from electric shock. Insulation class B (130°C) ensures long-lasting and trouble-free operation even at elevated ambient temperatures (up to 40°C).

Construction and mounting

The PTM 250 transformer is characterized by its compact dimensions (126 x 136 x 96 mm) and a weight of approximately 4.4 kg, which facilitates its installation in limited spaces. Mounting on a DIN TH-35 rail is quick and intuitive, and the spring clip further stabilizes the device. The housing made of plastic provides durability and resistance to mechanical damage.

Application and compliance with standards

The PTM 250 transformer finds application in a wide range of electrical installations, such as:

• Home automation systems
• Low-voltage lighting
• Powering controllers and regulators
• Laboratory equipment
• Electrical switchboards

The device meets the requirements of PN-EN 61558-2-4 and PN-EN 61558-2-6 standards, which confirms its safety and compliance with applicable regulations. The degree of protection IP21 provides protection against touching live parts and against the ingress of solid objects larger than 12.5 mm.

This transformer is characterized by a rated power of 250 VA, a primary voltage of 230 V AC and a secondary voltage of 24 V AC. Mounting is done on a DIN TH-35 rail, and the degree of protection is IP21. The insulation class is B (130°C), and the device is made as a safety transformer. Its dimensions are 126 x 136 x 96 mm, and the weight is approximately 4.4 kg.
