The E-T-A 3120-N series offers a reliable and cost-effective solution for protecting and switching electrical circuits. This specific model, the 3120-F72R-P7T1-A20Q-0.5A, is a thermal circuit breaker designed for panel mounting.
Key electrical specifications include a current rating of 500mA and a voltage rating of 250V. It operates as a 2-pole device with a thermal trip element, providing optimal overload protection. The rocker actuator allows for easy ON/OFF switching and manual reset after tripping, eliminating the need for fuse replacement.
This circuit breaker is designed to tolerate inrush current peaks from motors and transformers. Its bimetal trip element ensures faster tripping at high ambient temperatures, making it suitable for various applications where resistance is temperature-dependent. The unit replaces a switch, fuse-holder, and blade fuses, reducing mounting and wiring time, as well as planning and storage costs.
Compliance is noted with CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 approvals. The RoHS status is listed as RoHS3 Compliant, MSL as 1 Unlimited, and REACH as Unaffected.
