Control- and safety isolating transformer
USTE 40/2x12
Characteristics
Benefits
› Universal input voltages 208 to 600 Vac
› Very good switch-on behaviour thanks to reduced starting currents
› High power density due to a compact construction design
› Very good corrosion protection and low noise thanks to BLOCK IMPEX vacuum impregnation
› Quick to cable up thanks to the use of spring-clamp terminals
› Contact protected screw connection terminals complying with UVV BGV A3
› Simple mounting thanks to robust metal footplate with oval slots
› With combination footplate for bolted and rail mounting
