1-phase Power Transformers Product Sheet

Product catalog summary
Overview: The document describes the POWER SERIES, TYPE P/M6,3 - 20 kVA, a new series of 1-phase power transformers designed for energy, marine, and industrial applications. These transformers are noted for their cost-effectiveness, with 15-20% lower losses, and environmentally friendly manufacturing processes.
Specifications: The transformers range from 6.3 to 20 kVA, with primary voltage at 400V ± 2x2.5% and secondary voltage at 230V. They operate at a frequency of 50/60Hz and have an insulation class of F(155°C) / H(180°C). The isolation voltage is 4 kV AC, and they are designed for an ambient temperature of 40°C. The protection degree is IP00, and they belong to protection class I.
Standards and Compliance: These transformers comply with EN/IEC 61558-4 standards and can be manufactured according to additional norms such as DNV or LRS, or customer-specific specifications.
Technical Features: The transformers feature an open frame design with optional components like primary and secondary fuses, circuit breakers, on/off switches, thermal switches, thermal PT 100, inrush current limiting, and isolation monitoring devices.
Mechanical Data: The document provides detailed mechanical dimensions and weights for each transformer model, ranging from 6.3 kVA to 20 kVA, with terminal block sizes varying from 16mm² to 35mm².
Additional Options: Available models include horizontal models, IP23-54 encapsulated models, and low-loss Eco models. Transformers can also be designed with specific core constructions to limit inrush current to a maximum of 3.5 times the nominal current.
Manufacturer: Trafox, a brand of Muuntosähkö Oy, is responsible for the development, manufacturing, and customization of these transformers, along with other products like chokes, filters, and monitoring devices.
