It's designed for branch-circuit protection in industrial control panels, distribution boards, and similar enclosures where a compact MCCB footprint is needed. The 'K' characteristic curve defines the instantaneous trip threshold — typically 8 to 14 times rated current — making it suited for motor-starting loads or circuits with moderate inrush that a 'B' or 'C' curve might nuisance-trip on.
Sourcing and compliance
The S201P-K25 carries CE marking for European low-voltage directive compliance.
