About This Product

■Features

1. Determine whether it is lightning surge or load abnormality The "reset breaker" is an automatic power breaker restart device that will automatically restart the breaker only if it is tripped by a lightning surge (or opening/closing surge), and will not restart if there is a load abnormality such as a ground fault. Reduces the burden on workers. 2.Even if the breaker is tripped by lightning surge just before a power outage, it will automatically turn on again. 3.Record the number of operations The number of automatic reload operations can be managed and becomes valuable data for maintenance. 4. Compatible with various breaker types Earth leakage breaker type, no-fuse breaker type 5.Compact type also available (50A frame only) Space saving can be achieved when incorporating it into the power supply panel. There are other product numbers as well.
