The E-T-A 3120-N321-P7T1-W14DR3-5A is a two-pole thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a thermal-bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables. The breaker can be easily and quickly reset after tripping, and its positively trip-free mechanism ensures reliable disconnection.
Key electrical specifications include a voltage rating of 415V and a current rating of 5A. The internal resistance per pole is 0.0325 Ohm, and the typical life for a two-pole configuration is 50,000 cycles at 1x IN, inductive. It also features illumination with a red indicator at a nominal voltage of 115V.
This circuit breaker is designed for panel mounting and features a rocker actuator. It is approved by CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. The device is suitable for various applications including medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, and audio equipment.
Environmental compliance includes RoHS3 compliance, REACH unaffected status, and an MSL of 1. The compact design and resettable functionality contribute to increased equipment availability and reduced mounting and wiring time.
