Introduction

USW-1 Series thermal cutoffs — most models are CUL, TUL, and UL certified under UL file number E126429, with dual ratings (UL certified): 250V 10A and 125V 15A. Rated voltage: 250VAC and 125VAC; rated current: 10A at 250VAC, 15A at 125VAC; interrupting current: 250VAC, 15A. Transient overload test current: DC current pulse, amplitude 150A, duration 3ms, interval 10s, applied continuously for 100 cycles. Parameters including rated operating temperature, holding temperature, rated current, interrupting current, transient overload current, and rated voltage are also specified.
