Overcurrent circuit breaker S 312 2P C 6A 10000A TX3 404201

Reliable protection of electrical installations with Legrand S 312 circuit breaker

The S 312 2P C 6A circuit breaker is part of the TX³ series from Legrand, designed to effectively protect electrical circuits against the effects of overloads and short circuits. This two-pole circuit breaker with C characteristic, rated current of 6A and short-circuit breaking capacity up to 10kA, is a reliable solution for both home and professional installations.

Design and parameters for demanding applications

The S 312 circuit breaker is characterized by a compact design, occupying only 2 modules on a TH35 rail. Its solid construction guarantees long-lasting and trouble-free operation. Energy limitation class 3 provides adequate protection in the event of an electric arc. Rated voltage of 400V AC and insulation voltage of 500V ensure safe use in various conditions. The rated impulse withstand voltage Uimp is as high as 4kV, which further increases resistance to interference.

Versatility and easy installation

The S 312 TX³ circuit breaker is compatible with a wide range of accessories, such as auxiliary and signaling contacts, undervoltage and overvoltage release devices, and remote drives, allowing it to be adapted to individual installation needs. Mounting on a TH35 rail is quick and intuitive, and the ability to connect using comb or pin busbars facilitates installation work. The IP20 degree of protection provides basic protection against contact and ingress of solid objects.

• Short-circuit breaking capacity: 10 kA at 400 V AC and 16 kA at 230 V AC – high resistance to short-circuit currents.
• C characteristic: provides optimal protection against overloads and short-term current surges, ideal for circuits with receivers with high starting current (e.g. motors).
• Modular design: occupies only 2 modules on a TH35 rail – saving space in the switchboard.
• Expandability: compatible with a wide range of accessories – flexibility to adapt to installation needs.
• Safety: energy limitation class 3 and high insulation voltage – guarantee of safe operation.
• Durability: designed for long-term operation in demanding conditions.
