Industrial 4D13102G03 250A 3-Pole 277 V Circuit Breaker

Industrial 4D13102G03 250A 3-Pole 277 V Circuit Breaker is engineered to deliver dependable protection for demanding three-phase power systems. Identified by the part number 4D13102G03, this breaker is built to handle sizable loads while ensuring safe, rapid isolation of all three phases when protection is triggered.

Why this design matters for your setup:

• 3-Pole configuration provides simultaneous disconnect across all three phases, simplifying maintenance and enhancing safety for motors, conveyors, and other three-phase equipment.
• 250 A current rating supports heavy-duty feeders and large equipment, reducing nuisance trips on high-load start-ups and demanding demand periods.
• 277 V voltage rating aligns with commercial and light industrial distribution systems, making it a practical choice for facilities that run 277V circuits from their three-phase networks.
• Industrial-grade construction designed to withstand the rigors of real-world electrical environments, from manufacturing floors to bustling distribution centers.
• Reliable part compatibility with panels and switchgear that require a 3-pole 277V breaker, helping you maintain a cohesive, standards-aligned electrical distribution plan.

Key specifications

• Part Number: 4D13102G03
• Current rating: 250 A
• Poles: 3
• Voltage rating: 277 V

Ideal use cases

• Protect three-phase feeders feeding large motors, pumps, and compressors in manufacturing or processing facilities.
