4P 400V 125A Circuit Breaker Tongou TOD10-125

Product Description

The Magnetothermic 4P 400V 125A Tongou TOD10-125 is a four-pole isolator designed for three-phase networks with neutral that require high switching capacity. It supports 125 A at 400 V AC and offers visible disconnection, reliable isolation, and long mechanical life, making it ideal as a main switch or as a disconnection point before automatic protections.

Main Features

• 4 poles (3P+N) with 125 A rated and 400 V AC (50/60 Hz).
• Utilization category AC-22 suitable for mixed loads.
• Short-time withstand: 1500 A for 1 s; electro-mechanical life 10,000 cycles.
• High-pressure screw terminals; rigid conductor up to 35 mm².
• 35 mm DIN rail modular mounting; approx. width 72 mm (4 modules).
• Compliance with IEC/EN 60947-3 and GB 14048.3.

Advantages or Benefits

• Total disconnection with neutral for maximum safety and selectivity.
• Prepared for high currents with robust connections and low voltage drop.
• Quick installation and easy maintenance in existing panels.
• Reliable solution for frequent switching in demanding environments.
• Compact format that optimizes space on the DIN rail.

Purpose or Applications

Recommended for three-phase panels with neutral in commercial and light industrial settings: pumps, compressors, HVAC, IT/UPS racks, and general disconnection in photovoltaic and self-consumption installations.

Technical Specifications

Compatibilities

Installable in standard modular enclosures (e.g., Schneider Kaedra). Complements residual current devices and downstream automatic protections, as well as professional connection accessories.

The Magnetothermic 4P 400V 125A Tongou TOD10-125 guarantees four-pole high-amperage isolation with professional reliability and a compact format.
