Designed for smooth acceleration, protection, and control of standard induction motors, it operates on standard 600 VAC, 50\/60 Hz power systems. Featuring integrated auxiliary contacts rated for 5 A, the module reduces electrical current surges, torque peaks, and mechanical wear on downstream equipment during start-up and stop sequences.\u003c\/p\u003e\n\u003ch3\u003eSolid-State Motor Control \u0026amp; Protection\u003c\/h3\u003e\n\u003cp\u003eThe unit provides electronic motor protection against overloads and phase imbalances without the mechanical fatigue typical of conventional thermal relays. Its solid-state architecture allows precise parameter monitoring and thermal management for three-phase motor loads. By providing controlled voltage ramping during startup, it minimizes line disturbances and mechanical stress on couplings, belts, and gearboxes.\u003c\/p\u003e\n\u003ch3\u003eAuxiliary Interfacing \u0026amp; System Integration\u003c\/h3\u003e\n\u003cp\u003eEquipped with auxiliary contacts rated up to 5 A, the \u003cstrong\u003eQI3ZDP\u003c\/strong\u003e integrates directly into control circuits, enabling fault indication, status signaling, and interlocking with upstream line contactors or supervisory control devices. Its rugged enclosure and three-phase power path design make it suitable for legacy control panel maintenance and retrofits where controlled starting and electronic motor protection are required.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eQI3ZDP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eAstat Plus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eSolid State Overload Relays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e600 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase\u003c\/td\u003e\n\u003ctd\u003e3-Phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuxiliary Contact Rating\u003c\/td\u003e\n\u003ctd\u003e5 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.59 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus\u003c\/td\u003e\n\u003ctd\u003eDiscontinued by Manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the main function of the GE QI3ZDP in a motor control circuit?A: It provides controlled solid-state starting and electronic overload protection for 3-phase induction motors to eliminate starting current spikes and mechanical shock.\u003c\/p\u003e\n\u003cp\u003eQ: What are the auxiliary contact capabilities of the QI3ZDP?
