Thermal-magnetic UL489 DIN Rail Circuit Breakers – 4230-T Series

E-T-A's 4230-T series single/multipole miniature circuit breakers are ideal for a variety of applications

Image of E-T-A's 4230-T Series MCBsE-T-A's 4230-T are single/multipole miniature circuit breakers (MCBs) in accordance with EN 60947-2, UL 1077, and UL 489. The 4230-T has toggle actuation, visual status indication, a high rupture capacity and a positively trip-free snap action mechanism. A range of trip characteristics and add-on modules make the 4230-T suitable for a variety of applications.

Unlike other MCBs, engineers only need to purchase one breaker for 120 VAC/240 VAC/277 VAC/480 VAC and 60 VDC/125 VDC.
