The E-T-A 3120-N series circuit breaker combines protection and switching functions in a single component. This thermal circuit breaker utilizes a high-end bimetal strip tripping element, offering optimal overload protection and tolerating inrush current peaks from motors, transformers, and magnetic valves. The trip time is dependent on the peak and duration of the overcurrent, as well as the ambient temperature.
Designed for reliability and cost-effectiveness, the 3120-N eliminates the need for fuse replacement, as it can be easily reset after tripping. It reduces mounting and wiring time by integrating switch and fuse functions into one unit. This two-pole breaker has a 300mA current rating and a 250V voltage rating, suitable for panel mounting.
Key advantages include reduced planning and storage costs, as it replaces a switch, fuse-holder, and blade fuses. Its space-saving design makes it ideal for constricted areas, enhancing overall product reliability by minimizing single components and potential error sources. The rocker actuation is available with various options, and add-on modules for undervoltage release, magnetic trip, remote trip, and auxiliary contacts are also available.
