Overcurrent circuit breaker S 302 2P B 2 A 6000 A series TX3 403380

Protection of Electrical Installations with TX³ Series Circuit Breakers

The S 302 2P B 2A overcurrent circuit breaker is a member of the TX³ series, designed for reliable protection of electrical installations against the effects of overloads and short circuits. It is a critical component in every safe and efficiently operating electrical system, whether in residential or commercial buildings. Its two-pole construction ensures comprehensive protection of circuits.

Construction and Application

TX³ series circuit breakers feature a bottom mounting clip and insulated terminal shields, significantly simplifying and accelerating wire connection and installation. This design is highly valued by electricians who prioritize ease and speed of work. Thanks to compatibility with a wide range of auxiliary accessories—auxiliary and signaling contacts, under-voltage and over-voltage releases, remote operating mechanisms—these breakers can be customized to meet the specific requirements of any installation. The use of characteristic B ensures rapid response to short-circuit current surges, while still allowing for brief overload conditions without unnecessary circuit tripping—ideal for devices with motors or other components generating inrush current.

Key Features and Benefits

• High breaking capacity: Rated making and breaking capacity Icn is 6 kA at 400 V and 10 kA at 230 V, ensuring effective protection in the event of a short circuit.
• Characteristic B: Provides fast response to short-circuit currents, minimizing the risk of damage to installations and equipment. Allows for temporary overloads without unnecessary circuit interruption.
• Modular design: 2-module width facilitates installation in standard electrical distribution boards.
• Versatility: Under-plaster mounting capability increases installation flexibility across various types of systems.
• Safety: IP20 protection rating provides basic protection against accidental contact.
• Compliance with standards: Meets requirements of EN 60898 and EN 60947-2 standards, confirming quality and safety of use.
• Expandability: Compatibility with accessories such as auxiliary contacts and additional trip units enables functional customization to individual needs.
• Rated voltage: Designed for operation in installations with a rated voltage up to 400 V AC at a frequency of 50-60 Hz.
