Built with a 2-pole configuration and rated at 400 amps with up to 65 V DC operation, it delivers precise overload protection and stable performance even under demanding conditions. The hydraulic-magnetic trip mechanism ensures accuracy independent of ambient temperature, while precision current equalization technology provides balanced current sharing to minimize nuisance tripping. Though now discontinued, the GJ1P-Z4-4 remains a trusted breaker for legacy systems requiring high interrupting capacity and robust construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eModel \/ MPN: GJ1P-Z4-4\u003c\/li\u003e\n\u003cli\u003eType: Hydraulic-Magnetic Molded Case Circuit Breaker \/ GJ Series\u003c\/li\u003e\n\u003cli\u003eAmperage Rating: 400 A\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 65 V DC\u003c\/li\u003e\n\u003cli\u003ePoles: 2-Pole Configuration\u003c\/li\u003e\n\u003cli\u003eTrip Characteristics: Fast, Medium, or Slow Options\u003c\/li\u003e\n\u003cli\u003eInterrupting Capacity: Up to 25,000 A at 65 V DC (10,000 A at 160 V DC)\u003c\/li\u003e\n\u003cli\u003eTechnology: Hydraulic-Magnetic Trip, Temperature-Insensitive\u003c\/li\u003e\n\u003cli\u003ePrecision Current Equalization (PCE): Provides current balance across poles\u003c\/li\u003e\n\u003cli\u003eStatus: Discontinued by Manufacturer\u003c\/li\u003e\n\u003cli\u003eApplication: Industrial DC systems, telecom, transportation, HVAC, and power distribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Eaton GJ1P-Z4-4 Circuit Breaker provides reliable, temperature-stable circuit protection with high current capacity, making it a durable solution for demanding applications and legacy installations.\u003c\/p\u003e","brand":"Eaton","offers":[{"title":"Default Title","offer_id":49105242751232,"sku":"GJ1P-Z4-4","price":514.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/s-l1600_087a86ca-9128-4b2d-b2dd-e7426330c647.webp?v=1785543338","url":"https:\/\/alotechparts.com\/products\/gj1p-z4-4-eaton-circuit-breaker","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
