The 104-P10-4A is a miniaturised single pole thermal overcurrent circuit breaker designed for integral mounting with push-to-reset, tease-free, trip-free snap action mechanism compliant with EN 60934 (IEC 60934). This device features P10 blade terminals (DIN 46244-A6.3-0.8, QC .250) and is rated for 4 A at AC 240 V or DC 48 V, with an internal resistance of 0.067 O. The circuit breaker operates across an ambient temperature range of -20°C to +60°C and provides an interrupting capacity of 6 × IN at DC, with typical life expectancy of 3,000 operations at 2 × IN under inductive conditions. It is approved to multiple international standards including VDE EN 60934, UL 1077, CSA C22.2 No 235, and CQC GB 17701, making it suitable for motors, transformers, solenoids, printed circuit boards, hand-held machines, appliances, marine applications, and caravans.
