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.
If avoiding the inrush current peak, the transformer can be fused with a value lower than his nominal current.
