Overcurrent breaker S 312 2P C 63 A 10000 A series TX3 404211

Protection of electrical installations with TX³ series circuit breakers

The S 312 2P C 63 A thermal-magnetic circuit breaker is a protective device that effectively safeguards electrical installations against the effects of overloads and short circuits. Essential in both residential and commercial buildings, it ensures safe and reliable operation of electrical equipment. Designed to handle a wide range of loads, it is an ideal solution for installers and users seeking robust and efficient protection.

Construction and application

This breaker belongs to the TX³ series, characterized by a modern design and high manufacturing quality. Designed for DIN rail TH35 mounting, it occupies 2 module widths, enabling optimal space utilization in distribution boards. The C characteristic provides delayed tripping during short-term overloads, which is particularly important for devices with electric motors or other impulse loads. The rated current of 63 A makes it suitable for protecting circuits with higher power demands.

Key features and benefits

• High breaking capacity: Rated short-circuit breaking capacity of 10 kA at 400 V and 16 kA at 230 V ensures effective protection in the event of a short circuit.
• C characteristic: Provides protection against overloads and short circuits while allowing brief current surges without unnecessary tripping—ideal for motor-driven equipment.
• Flush mounting: Enables aesthetic and discreet installation within walls or other structural elements.
• Expandability: Compatibility with additional accessories (auxiliary contacts, trip units) allows customization of the breaker’s functionality to meet specific installation requirements.
• Safety: Complies with EN 60898-1 and EN 60947-2 standards, confirming its safety and reliability.
• Durable construction: Manufactured from high-quality materials resistant to mechanical damage and environmental conditions.
• IP20 protection rating: Protects against finger contact and ingress of solid objects larger than 12.5 mm in diameter.

TX³ series circuit breakers are a proven choice for professionals and users who value the safety and reliability of their electrical installations. Their robust construction and advanced features ensure long-term protection against the consequences of overloads and short circuits.
