Specifications
Product Description
The Magnetothermic 2P 400V 125A Tongou TOD10-125 is a two-pole load break switch capable of handling high currents on 400 V AC lines. Its AC-22 category makes it suitable for switching mixed loads commonly found in real installations (motors with moderate starting, resistors, switched-mode power supplies), providing a defined disconnection and safe circuit isolation. It is designed to function as a main switch, maintenance switch, or as an isolation point before automatic protections.
Main Features
- 2 poles with 125 A rated and 400 V AC at 50/60 Hz.
- Utilization category AC-22 for mixed loads with good switching capacity.
- Short-term thermal withstand: 1500 A/1 s; electro-mechanical life 10,000 cycles.
- Reinforced screw terminals and rigid conductor capacity up to 35 mm².
- Modular format for 35 mm DIN rail with a narrow design that saves space.
- Construction in accordance with IEC/EN 60947-3 and GB 14048.3 for maximum reliability.
Advantages or Benefits
- Operational safety: visible disconnection and galvanic isolation of the circuit.
- Prepared for high currents with low voltage drop and robust terminals.
- Simple installation and maintenance; ideal for frequent switching operations.
- Versatile use as a main switch for subpanels or equipment.
- Fully compatible with standard market enclosures and DIN rails.
Purpose or Applications
Recommended for distribution panels in commercial and light industrial settings, pumping systems, HVAC, workshops, UPS/inverters, and subpanels of photovoltaic systems where high-current bipolar isolation and frequent operation are required.
