TTZ EOR / TUM/K - Transformers for electrical rail heating systems
Single-phase transformers, toroidal (TTZ EOR) or open (TUM/K), intended for power supply of railway turnouts heating systems. Cast resin enables the usage in humid environment, prevents the transformer from mechanical damages and harsh weather conditions.
TTZ EOR transformers are made with Class II insulation and protection grade IP00. Maximum ambient temperature is 40°C. Thermal classification: B (130°C). Manufactured in compliance with EN61558-1, EN61558-2-4 (2,5; 3,0; 4,0; 5,0kVA), EN61558-2-6 (0,15; 0,2kVA).
TUM/K transformers are made with Class I insulation and protection grade IP00. Maximum ambient temperature is 40°C. Thermal classification: B (130°C). Manufactured in compliance with EN61558-2-4.
Rated power: 0,15; 0,2; 2,5; 3,0; 4,0; 5,0kVA (TTZ EOR), 2,5kVA (TUM/K)
