Thermal Magnetic Overcurrent Circuit Breakers

Thermal Magnetic Overcurrent Circuit Breakers

Typical Applications
Ideally suited to protect against overcurrent and short circuit of equipment in telecommunications, process control and other industrial applications where sophisticated equipment requires a high precision performance.
Technology 
A latching type bimetal is combined with a magnetic coil to ensure protection and genuine physical contact isolation. This provides the joint benefits of delayed operation for low level overcurrent protection and fast magnetic action of higher value short circuits, disconnecting the faulty circuit within milliseconds.
