Transformer Series STA

Brand: R. STAHL AG

The application of a control transformer is demanding EN 60204-1for control circuits (few exceptions).

The protection of transformers has to be primary with a Motor protection circuit-breaker in tripping class 10 or 10 A. 

Our circuit breaker (Type 8523/8.) will be adjusted according the current rating of the transformer (see attached table). 

Secondary a miniature fuse or a MCB should be used. 

The criterions are: Protective measures against direct or indirect contact (see also IEC 60364-4-43), line protection, overload protection of switching devices (welding of contacts). 

All electrical settings of control circuit according to manufacturers' instructions. 

A minimum distance of 40 mm to all other components has to be kept.
Features
  • Low voltage drop in switching inductive loads
  • Flexible voltage adjustment by primary tapping (±5%)
  • Limitation of short-circuit current in control circuit
  • Typical applications: Control voltage circuits, functional extra-low voltage PELV, safety extra-low voltage SELV, protective separation (of circuits)
