This E-T-A 4230-T series miniature circuit breaker (MCB) is a thermal-magnetic type with a 35A current rating and a 3-pole configuration. It is designed for reliable protection of cables, motors, generators, and transformers, as well as electronic equipment like computers and telecommunication systems.
The breaker conforms to EN 60947-2, UL 1077, and UL 489 standards, offering a high rupture capacity of up to 10,000 A. It supports a wide range of operating voltages, including AC 240V/415V and DC 80V/125V per IEC/EN standards, and AC 277V/480Y/277V and DC 60V/125V per UL standards.
Designed for DIN rail mounting, the 4230-T130-K0CE-35A features screw terminals for secure connections. It operates within an ambient temperature range of -35°C to +70°C and has a mechanical life of 20,000 cycles and an electrical life of 6,000 cycles. The breaker provides a degree of protection IP20 and meets stringent environmental testing standards for vibration, shock, corrosion, and humidity.
The nominal current rating is 35 A under IEC/EN 60947-2.
Under IEC/EN 60947-2 it is rated for AC 240 V, AC 415 V, DC 80 V, and DC 125 V. Under UL 1077 and UL 489 it is rated for AC 277 V, AC 480Y/277 V, DC 60 V, and DC 125 V.
Rupture capacity is 7,500 A under IEC/EN 60947-2 (Ics) and 10,000 A under IEC/EN 60947-2 (Icu) and UL 489.
The ambient temperature range is -35°C to +70°C.
It is designed for DIN rail mounting.
It uses screw terminals with a maximum tightening torque of 2 Nm and a stripping length of 14 mm.
It is approved to IEC/EN 60947-2, UL 1077 / CSA-C22.2 No. 235, UL 489 / CSA-C22.2 No. 5, and TÜV.
