The E-T-A 4230-T110-K0BE-32A is a single-pole, thermal-magnetic miniature circuit breaker (MCB) designed for reliable circuit protection. It conforms to EN 60947-2, UL 1077, and UL 489 standards.
This breaker features a 32A current rating and a voltage rating of 277 VAC or 60 VDC. It is designed for DIN rail mounting, making installation straightforward in control panels and enclosures. The thermal-magnetic tripping mechanism ensures protection against overloads and short circuits.
Key specifications include a rupture capacity of 10,000 A (AC/DC) to UL 489 and IEC/EN 60947-2 (Icu), and 7,500 A (AC) / 10,000 A (DC) for Ics. It operates within an ambient temperature range of -35°C to +70°C and has a degree of protection IP20.
Typical applications include the protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, industrial process control systems, telecommunications equipment, and power supplies. Its robust construction and high rupture capacity make it suitable for demanding environments.
AC ratings: 240V (IEC/EN 60947-2), 277V (UL 1077/489), 120V (UL 489). DC ratings: 80V, 125V (IEC/EN 60947-2), 60V, 125V (UL 1077/489).
