The 104-PR-10A is a miniaturised single pole thermal overcurrent circuit breaker designed for PCB mounting with solder terminal pins, featuring a push-to-reset, tease-free, trip-free snap action mechanism compliant with EN 60934 (IEC 60934). It is rated for current ratings from 0.05 to 10 A with a voltage rating of AC 240 V or DC 48 V (UL: AC 250 V; DC 48 V), and operates reliably across an ambient temperature range of -20°C to +60°C. The device exhibits typical internal resistance values that vary with current rating (for example, 0.9 O at 1 A and =0.05 O at 10 A), and provides an interrupting capacity of 6 × IN at DC. This circuit breaker is widely used in motors, transformers, solenoids, printed circuit boards, hand-held machines, appliances, marine applications, and caravans, where reliable overcurrent protection and compact form factor are essential.
