Control transformer MCL series

electrical power supplyencapsulatedsingle-phase

MCL Range Control Panel Transformers offering 230V and 400V with adjustment tappings. Designed and manufactured to comply with IEC61558. This high quality product is manufactured using automated winding and welding machines; they offer good access to the four-hole fixing, touch-proof terminals and full varnish impregnation to protect against humidity. • Control Transformer : Class 1 Isolation Transformer with Earth Screen between Primary and Secondary • Standard : IEC / BS-EN 61558 • Insulation Class : B • Insulation Resistance : > 5 Meg Ω • Dielectric Strength : Primary to Secondary > 2.5kV Primary to Earth > 2.5kV Secondary to Earth > 2.5kV • Ambient Temperature : 40 Transformer Circuit Protection Transformers must be protected against short circuit and overload. Primary Circuit The primary side of the Transformer should be protected against short circuit thereby cutting the supply voltage in the event of a short circuit fault. The rating of the primary protection device has to take into account the high inrush current during energizing of the Transformer.
