The 106-M2-P10-4A is a miniaturised single-pole thermal overcurrent circuit breaker designed for threadneck panel mounting with a 3/8-27UNS thread, collar, metal hex nut, and plastic knurled nut. It features A6.3-0.8 (QC .250) blade terminals, push-to-reset operation, and a tease-free, trip-free snap action mechanism compliant with EN 60934 (IEC 60934). The device is rated for AC 240 V and DC 48 V (UL: AC 250 V; DC 48 V), with current ratings from 0.05 to 10 A and an interrupting capacity of 6 × IN at DC. It operates reliably across an ambient temperature range of -20 °C to +60 °C, with an insulation resistance exceeding 100 MO (DC 500 V) and a dielectric strength of AC 3,000 V in the operating area. The breaker is commonly used in motors, transformers, solenoids, printed circuit boards, hand-held machines, appliances, marine applications, and caravans, providing dependable overcurrent protection with minimal nuisance tripping.
