The E-T-A 3120-N series circuit breaker/switch combination is a versatile component designed for protecting and switching electrical circuits. This specific model, 3120-F72R-N7M1-A30QG4-16A, features a thermal trip element for reliable overload protection. It operates at a current rating of 16A and a voltage rating of 250V, with a 2-pole configuration.
Designed for panel mounting, this circuit breaker integrates the functions of a switch, fuse holder, and blade fuses into a single unit, reducing mounting time, wiring, and stocking expenses. The rocker actuator is illuminated green, with a nominal illumination voltage of 230V. After tripping due to an overcurrent event, the 3120-N can be easily and quickly reset, eliminating the need for fuse replacement.
Advantages of the bimetal trip element include tolerance for inrush current peaks from motors and transformers, and faster tripping at high ambient temperatures. This component offers a space-saving design and enhanced reliability by reducing the number of single components in a system. It is suitable for applications requiring robust overcurrent protection and switching functionality.
