This E-T-A 4230-T series miniature circuit breaker (MCB) is a thermal-magnetic type designed for reliable circuit protection. It features a single pole configuration and is rated for 15A current.
The breaker supports a voltage rating of 277VAC or 60VDC. It is designed for convenient DIN rail mounting, making it suitable for various industrial and telecommunications applications.
Key technical specifications include a rupture capacity of 10,000A (AC/DC) to UL 489 and IEC/EN 60947-2 standards. The operating ambient temperature range is -35°C to +70°C. The terminals are screw type, with a maximum tightening torque of 2 Nm and support cable cross-sections up to 35 mm².
Typical applications include protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, industrial process control systems, telecommunications equipment, and power supplies.
The voltage rating depends on the standard: IEC/EN 60947-2: AC 240 V, DC 80 V; UL 1077: AC 277 V, DC 60 V; UL 489: AC 120/240/277/480Y/277 V, DC 60 V (125 V with 2 poles in series).
