Overcurrent protection devices help protect against harmful overcurrent surgest and over temperature faults. These devices limit the flow of dangerously high current during fault conditions.
Circuit breakers offer ratings from 20mA to 50A. Thermal types include 1- and 2- pole units. Magnetic models are 1- to 4-pole devices. All series meet UL 1077 requirements, and several types meet ignition protection according to UL 1500.
Our low-profile, surface-mount fuses address a broad range of overcurrent protection applications. Chip fuses provide performance stability to support applications with current ratings from .5ADC up to 20ADC.
PolySwitch devices are polymeric positive temperature co-efficient devices, which are used to help protect against damage caused by harmful overcurrent surges and over temperature faults. They limit the flow of dangerously high current, however, they reset after the fault is cleared and power to the circuit is removed.
