The 2-5700-IG1-K10-DD-2.5A is a single-pole thermal overcurrent circuit breaker designed for overcurrent protection in low-voltage applications. It features a press-to-reset, tease-free, trip-free snap action mechanism with a 2.5 A current rating, moulded threadneck 3/8"-27UNS-2A mounting, and M4x6 screw terminals (K10 design). The device is rated for AC 250 V and DC 28 V operation, with an interrupting capacity of 8 × IN (20 A) and typical internal resistance of 0.2 O at 2.5 A. It operates reliably across an ambient temperature range of -20°C to +60°C and meets international safety standards including IEC/EN 60934 (VDE), UL 1077, and CSA C22.2 No 235. This circuit breaker is ideal for protecting motors, transformers, solenoids, battery chargers, power supplies, and other electrical equipment in industrial and commercial applications.
