Schneider Electric GoPact MCCB G80N3TM630 | 3-Pole, 630A, 50kA, Adjustable Thermal-Magnetic Circuit Breaker

Schneider Electric GoPact MCCB G80N3TM630 is an industrial-tier, high-capacity Molded Case Circuit Breaker designed to provide total safety and grid resilience in demanding commercial and heavy-duty low-voltage networks. Engineered within the ruggedized GoPact 800 frame size, this 3-pole breaker features a powerful 630A continuous current rating combined with an elite short-circuit breaking capacity of 50kA at 415VAC. It is purpose-built to safeguard large-scale downstream infrastructure, busbar systems, and distribution lines against destructive short circuits and continuous thermal overloads.

Equipped with an advanced Thermal-Magnetic Distribution (TMD) trip unit, the G80N3TM630 offers adjustable thermal protection, giving engineering teams the flexibility to calibrate the overload threshold precisely to match down-line wiring or transformer capacities. Backed by the global manufacturing excellence of Schneider Electric, this 630 Amp MCCB is widely specified for Main Low-Voltage Distribution Boards (MDB), heavy factory infrastructure feeders, manufacturing plant sub-stations, and central HVAC chiller groups. It represents the perfect professional choice for high-spec Egyptian projects demanding original brand certification and cost-optimized value engineering.

Key Technical Features:

• 630A Continuous Current Rating: Optimized for intermediate industrial feeders, large sub-main panels, and high-power machinery.

• 50kA High-Fault Breaking Capacity: Delivers exceptional electrical resilience and fault interruption close to primary step-down transformers.

• Adjustable Thermal Protection: Integrated TMD trip unit allows precise manual tuning of overload thresholds for optimal circuit coordination.

• 3-Pole Three-Phase Isolation: Concurrent mechanical tripping across all three live phases completely eliminates single-phasing motor damage hazards.

• GoPact 800 Heavy-Duty Housing: Built with ruggedized, heat-resistant molding and deep arc-chutes to safely absorb severe electrical fault energy.

• Accessories Ready: Fully compatible with auxiliary switches, shunt trips (MX), undervoltage trips (MN), and ergonomic extended rotary handles.
