Thats normally impossible: Toroidal Transfo fused with Line protector B-characteristic with nominal current value.
Normally impossible: A 1kVA toroidal Transformer fused with a B-character Line protector switch with nominal current value. It´s okay only than, if a TSRL is connected opposite the transfo, and therefore the inrush current is avoided in all circumstances.
Toroidal transformers are transfos for energysaving
