4230-T Thermal-Magnetic Miniature Circuit Breakers

E-T-A Circuit Breakers 4230-T Thermal-Magnetic Miniature Circuit Breakers (MCBs) are single-pole and multi-pole circuit breakers for DIN rail mounting with toggle actuation, visual status indication, and high rupture capacity. A positively trip-free snap action mechanism ensures reliable switching behavior. A range of trip characteristics and add-on modules make the 4230-T suitable for a variety of applications. The ETA MCBs are rated IP20 and are in accordance with EN 60947-2, UL 1077, and UL 489. E-T-A Circuit Breakers 4230-T Thermal-Magnetic MCBs are ideal for the protection of cables, motors, generators and transformers, thyristors and silicon rectifiers. The components also offer protection for computers and their peripheral equipment, industrial process control systems, telecommunications equipment, and power supplies.
