The E-T-A 3120-N321-P7T1-W01D-16A is a thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a bimetal trip element for reliable operation and is suitable for overload protection of motors, pumps, transformers, and cables. This two-pole breaker has a current rating of 16A and a voltage rating of 250VAC or 50VDC.
Designed for panel mounting with a rocker actuator, this circuit breaker offers a positively trip-free mechanism ensuring reliable disconnection even with a blocked actuator. It can be easily and quickly reset after tripping. The internal resistance at 16A is less than 0.02 Ohms. Typical life expectancy is rated at 30,000 cycles for single-pole operation under specific conditions and 50,000 cycles for two-pole operation.
This thermal circuit breaker is suitable for various applications including medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. It holds approvals from CSA, GB, IEC, and UL.
