Miniature Circuit Breaker 1P 230V 125A Tongou TOD10-125

Product Description

The Magnetothermic 1P 230V 125A Tongou TOD10-125 is a load-break switch (isolator) with one pole, designed for single-phase lines that require high switching capacity and safe circuit isolation. With a nominal rating of 125 A at 230 V AC and utilization category AC-22, it allows reliable switching of mixed loads (inductive and resistive), offering visible disconnection, long service life, and a narrow modular format for DIN rail mounting. It is the professional choice when a 1P isolation point is needed before automatic protections or as a main switch for subpanels and equipment.

Main Features

• 1 pole, 125 A nominal, 230 V AC, 50/60 Hz.
• Utilization category AC-22 for switching mixed loads in service.
• Short-time withstand: 1500 A for 1 s; electro-mechanical life: 10,000 operations.
• Reinforced screw terminals; accepts rigid conductor up to 35 mm².
• 1-module format (≈18 mm) for 35 mm DIN rail; quick and compact installation.
• Compliance with IEC/EN 60947-3 and GB 14048.3 for load-break isolation.

Advantages or Benefits

• Operational safety: visible disconnection and galvanic isolation of the circuit during maintenance.
• Prepared for high currents with low voltage drop and high-pressure terminals.
• Optimizes panel space thanks to its 18 mm width and standard DIN mounting.
• Proven durability (10,000 cycles) that reduces downtime and maintenance costs.
• Versatile use as a general 1P switch or isolation point upstream of protections.

Purpose or Applications

Recommended for residential and commercial single-phase subpanels, high-demand socket lines, power supply for thermal equipment, upstream single-phase EVSE (as isolator), light machinery, and backup systems where safe isolation of 125 A at 230 V AC is required. Also useful in photovoltaic or self-consumption environments as a disconnection and maintenance element before automatic protections.

Technical Specifications

Compatibilities

Installable in standard modular enclosures and panels (e.g., Kaedra-type families). Complements residual current devices and automatic circuit breakers downstream, as well as professional terminals and ferrules for safe connections.

The Magnetothermic 1P 230V 125A Tongou TOD10-125 combines reliable isolation, compact format, and industrial standards to safely manage high-current single-phase lines.
