Aihara Denki Accident recurrence prevention transformer

Even if an abnormal situation occurs in the transformer, the transformer itself has the ability to cut off the power supply.
The transformer with built-in thermal fuse becomes unusable in one accident, but the "EP series" can be used more than 300 times with the guaranteed number of thermal protectors.
Conventional transformers with thermal protectors repeat accident recurrence until the contacts are restored and the abnormal situation is resolved when the temperature drops, or until the breaker is tripped.
There are system circuits that avoid the above conditions, but for that purpose, it is necessary to incorporate an accident holding circuit that uses breaks and magnets.
Although parts costs and work costs will be incurred, the "EP series" can prevent the recurrence of accidents by using the same wiring as before.
