Fuji Electric Co., Ltd. TK-E2-4-6 Overload Relay

Fuji Electric Co., Ltd. TK-E2-4-6 overload relay is a current-sensing protective device with a rated current range of 4–6 A, designed to monitor load current in motor circuits and trigger an automatic trip when the threshold is exceeded. Specified by the part number TK-E2-4-6, this relay identifies a precise 4–6 A overload protection option in Fuji's line of industrial relays. In operation, it helps prevent motor overheating and equipment damage by interrupting current flow during sustained overcurrent events within its rated range. The 4–6 A rating communicates the exact current window at which protection activates, guiding proper selection for installations that operate around that current level. Using a dedicated overload relay like TK-E2-4-6 contributes to safer electrical practices by providing a focused response to excessive current, which can indicate overload or fault conditions in the motor circuit.
