The 4230-T130-K0CE-30A is a three-pole, thermal-magnetic miniature circuit breaker rated for 30A and designed for DIN rail mounting. This device features a C characteristic curve, with a thermal trip between 1.05-1.30 times the rated current and a magnetic trip between 6.4-9.6 times the rated current. It is equipped with screw terminals for secure connections and holds IEC/EN 60947-2 and UL 1077 approvals. The breaker has a high rupture capacity of 10,000 A (Icu) per IEC/EN 60947-2 and operates reliably across an ambient temperature range of -35°C to +70°C. Common applications include protecting cables, motors, industrial process control systems, and telecommunications equipment.
