Title:
CIRCUIT INTERRUPTER WITH IMPROVED SURGE SUPPRESSION
Document Type and Number:
WIPO Patent Application WO/2013/019284
Kind Code:
A3
Abstract:
A circuit interrupter, such as a GFCI or AFCI product, is provided having a suppression and protection circuit and circuit interrupter circuitry. In one configuration, a semiconductor device and a voltage clamping device or surge protector, such as a metal oxide varistor (MOV), are utilized in the circuit interrupter for handling transient surges and overvoltage conditions. The semiconductor device, such as a SIDCA and a TVS diode, is connected to a solenoid or trip coil of the circuit interrupter circuitry to limit the amount of current through the semiconductor device. The MOV is placed between phase and neutral conductors of the circuit interrupter circuitry.
