The 2-5700-IG1-K10-DD-30A 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 push-to-release/push-to-reset (DD) operation and M4x6 screw terminals (K10). The breaker is equipped with a moulded iG1 threadneck (3/8"-27UNS-2A) for secure panel mounting with a maximum tightening torque of 1 Nm. It is rated for AC 250 V and DC 28 V operation with a current rating range of 0.05 to 25 A, and operates reliably across an ambient temperature range of -20°C to +60°C. The device meets international standards including IEC/EN 60934 and UL 1077, with an interrupting capacity of 300 A at 13–25 A ratings. Typical applications include motor protection, transformers, solenoids, battery chargers, power supplies, and machinery, where reliable thermal overcurrent protection is essential.
