The 4230-T110-K0BE-8A is a single-pole thermal-magnetic miniature circuit breaker designed for DIN rail mounting with toggle actuation and visual status indication. It features a rated current of 8 A, operates at AC 240 V (1-pole) or AC 415 V (multi-pole configurations), and incorporates a positively trip-free snap action mechanism for reliable switching behavior. The device meets IEC/EN 60947-2 and UL 1077 standards, with an insulation coordination of overvoltage category III (Uimp 4 kV) and pollution degree 3, providing robust protection against electrical faults. It is equipped with screw terminals supporting cable cross-sections up to 35 mm², operates reliably across an ambient temperature range of -35°C to +70°C, and is suitable for protecting cables, motors, generators, transformers, and industrial control systems.
