Schneider Electric GoPact MCCB G25F3A250 | 3-Pole, 250A, 36kA, Adjustable Thermal-Magnetic Circuit Breaker

Schneider Electric GoPact MCCB G25F3A250 is a high-capacity Molded Case Circuit Breaker engineered to deliver uncompromised circuit protection and system reliability in commercial and industrial low-voltage networks. Built within the heavy-duty GoPact 250 frame size, this 3-pole breaker features a 250A continuous current rating paired with a robust short-circuit breaking capacity of 36kA at 415VAC. It is purpose-built to safeguard large-scale electrical infrastructure against destructive short circuits and continuous thermal overloads.

Equipped with an advanced Thermal-Magnetic Distribution (TMD) trip unit, the G25F3A250 offers adjustable thermal protection, giving engineering teams the flexibility to calibrate the overload threshold precisely to match downstream wiring and cable capacities. Backed by the global manufacturing excellence of Schneider Electric, this 250 Amp MCCB is widely specified for main low-voltage distribution boards (LVDB), sub-distribution panels, heavy HVAC compressor banks, and commercial water pump stations. It represents the perfect professional choice for Egyptian projects demanding original brand certification, long mechanical lifecycles, and cost-effective value engineering.

Key Technical Features:

• 250A Continuous Current Frame: Optimized for main incoming panels, commercial sub-feeders, and high-capacity machinery lines.

• 36kA Fault Breaking Capacity: Provides standard-compliant commercial and light industrial fault interruption certified to IEC 60947-2.

• Adjustable Thermal Protection: Built-in TMD trip unit allows field-tuning of overload thresholds for optimal circuit coordination.

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

• GoPact 250 Rugged Housing: Built with high-grade, heat-resistant molding and efficient internal arc-chutes.

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