[Case Study] Circuit Breaker CBY-100 Battery Charger

[Case Study] Circuit Breaker CBY-100 Battery Charger

The rated current is 5 to 25A! A case where the bimetal can protect the circuit from interruption.

We would like to introduce a case study of the implementation of the "CBY-100" for customers in the charger industry. In response to concerns about the need for a device to protect against risks such as damage from reverse connection and overload, we proposed protection using an auto-reset circuit breaker. By implementing this product, the bimetal can now protect the cutoff circuit from the heat generated during an overload. 【Case Overview】 ■Issue - A device is needed to protect against risks such as damage from reverse connection and overload. ■Result - The bimetal protects the cutoff circuit from the heat generated during an overload. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Circuit Breaker CLA-500 Electric Vehicle Circuit Protection

[Case Study] Circuit Breaker CLA-500 Electric Vehicle Circuit Protection

The rated current is 10 to 60A! Automatically resets after about 30 seconds following a breaker trip.

We would like to introduce a case study involving the bimetallic circuit breaker 'CLA-500' that we handle. Our customer in the charger industry was in a situation where they needed a device to protect against dangers such as internal circuit failures. Therefore, we proposed protection using an auto-reset circuit breaker. As a result of its implementation, the bimetallic component can now protect the circuit from damage due to overheating during overload conditions. [Case Overview] ■ Issue - A device is needed to protect against dangers such as damage from reverse connections or overloads, as well as internal circuit failures. ■ Result - During overload conditions, the heat generated allows the bimetallic component to protect the circuit from damage. *For more details, please refer to the PDF document or feel free to contact us.
