3P 400V 100A Circuit Breaker Tongou TOD10-125

Product Description

The Magnetothermic 3P 400V 100A Tongou TOD10-125 is a high-amperage load-break isolator for three-phase networks at 400 V AC. Designed to function as a main switch or isolation point prior to automatic protections, its AC-22 category ensures reliable switching in mixed loads, offering visible disconnection and safety during operations and maintenance in demanding installations.

Main Features

• Three-phase 3P with 100 A rated at 400 V AC (50/60 Hz).
• Utilization category AC-22 for mixed loads in service.
• Short-time withstand: 1500 A for 1 s; service life of 10,000 cycles.
• Reinforced screw terminals; accepts rigid conductors up to 35 mm².
• Modular format for 35 mm DIN rail; width of 3 modules (≈54 mm).
• Compliance with IEC/EN 60947-3 and GB 14048.3.

Advantages or Benefits

• Safety and reliability in recurring high-amperage operations.
• Quick integration into existing panels without taking up extra space.
• Robust connections that minimize heating and voltage drops.
• Versatility: main switch, subpanel or equipment isolation.
• Low cost and long mechanical life to reduce downtime and maintenance.

Purpose or Applications

Ideal for three-phase distribution panels in commercial and light industrial settings, pumps and compressors, HVAC, workshops, IT/UPS racks, and solar installations where 3P 100 A isolation with frequent and safe operation is required.

Technical Specifications

Compatibilities
