General Electric TJK436Y400 Molded Case Switch

General Electric TJK436Y400 Molded Case Switch is a 400 A, 600 V, 3-pole device that provides a hard off for power in electrical distribution and control circuits. It comes with an auxiliary switch for signaling or interlocking and an undervoltage feature to help ensure the switch remains in the desired position under low-voltage conditions. With molded case construction designed for durability, this switch is suited for use in panelboards, motor control centers, and other industrial installations where reliable isolation and controlled power interruption are required. The TJK436Y400 designation identifies the exact current rating, voltage rating, and pole count, making it a precise replacement or upgrade option within GE's line of molded case switches when a 400 A, 600 V, 3-pole unit with auxiliary signaling is needed.
