Key Mini-Breaker Specifications

The trip temperature of the mini-breaker is a key specification to battery pack manufacturers and Bourns has developed the ability to target specific trip temperature values. The combination of both the composite bi-metal material and the precision forming of the bi-metal disc allows Bourns to target trip temperatures from 72°C to 90°C within a ±5°C accuracy. As the chart here shows, the 72°C TCO device, for example, will trip between 67°C and 77°C, and so on.
