Mini automotive circuit breaker adds safety feature

E-T-A CIRCUIT BREAKERS Models 1620 and 1626 Type 2 version of automotive min circuit breaker with added safety benefits, provide a modified reset to SAE J553, which means the contacts stay in the open position until the load voltage is removed. The reset process begins only after the voltage is removed, ensuring the breaker won’t automatically reset to cause more damage. An additional heating element allows the contacts to be kept open that will heat up the bimetal disk in the tripped state to prevent automatic snap-back operation.
