Understanding circuit breaker design and operation to improve safety and reliability in underground mining
Interchangeable thermal‑magnetic trip (T207) delivers precise protection coordination, shrinking nuisance trips and reducing unplanned outages. This aligns with mining feeder protection and motor control in demanding environments. The 800 A amperage rating paired with a 2000–4000 A magnetic trip range enables scalable protection for large mining feeders, resulting in faster fault clearing at high current levels and minimized arc exposure during fault events. Voltage accommodations cover 1000Y/577 Vac and 250 Vdc, enabling safe protection of mixed AC/DC mining loads and supporting retrofit projects or future expansions without swapping protection devices. Three‑pole M‑frame construction with a rear 2A‑2B auxiliary switch with right pigtail simplifies status signaling and remote coordination, while the terminals are designed without terminals to allow flexible connection options in space‑constrained panels. The interrupt ratings reach 25 kAIC at 600 V and scale to 22 kAIC at 250 Vdc, 35 kAIC at 480 V, and 18 kAIC at 1000Y/577, ensuring robust fault interruption across mining power systems. With dimensions of 4.06 in depth, 16 in height, 8.25 in width and a weight of 29 lb, it fits rugged installations while offering dependable protection and a clear maintenance path. A one‑year warranty (or 18 months from shipment) provides manufacturing defect coverage per Eaton policy.

FAQs
This three‑pole M‑frame mining MCCB is designed for rugged mining panels. With a 4.06 in depth, 16 in height, and 8.25 in width, it fits in space‑constrained enclosures. It ships without terminals, so plan bus connections or lugs accordingly and ensure adequate clearance for clearance/ventilation and the rear 2A‑2B auxiliary switch wiring.
Amperage rating is 800 A with a magnetic trip range of 2000–4000 A. Voltage rating is 1000Y/577 Vac and 250 Vdc. Trip type is T207. Interrupt ratings include 25 kAIC at 600 V, 22 kAIC at 250 Vdc, 35 kAIC at 480 V, and 18 kAIC at 1000Y/577. It is a three‑pole M‑frame device with no terminals included and an auxiliary switch 2A‑2B rear with right pigtail.
Yes. Built as a mining class device with an M‑frame and high interrupt capability, it is intended for demanding mining feeders and switchgear. Its three‑pole design supports coordinated protection of multi‑line circuits, and the accessory rear auxiliary switch enables remote signaling for safer operation in underground environments.
