Overcurrent breaker S 301 1P D 4 A 6000 A series TX3 403716

Safety and Reliability in Your Electrical Installation

This single-pole overcurrent circuit breaker from the TX3 series is a critical component for protecting electrical circuits against the effects of overloads and short circuits. Designed with both professional installers and end-users in mind, it delivers effective protection and easy installation. Featuring a rated current of 4A and a D characteristic, it is the ideal solution for circuits connected to devices generating high inrush currents, such as motors or transformers.

Design and Application

The S 301 1P D 4A circuit breaker is designed for DIN-rail mounting. Its compact dimensions (width: 1 module, depth: 44 mm) enable efficient use of space in distribution boards. The ability to connect conductors from either the top or bottom, combined with screw-type terminals, ensures convenient and secure connections. Constructed from high-quality materials, it guarantees long-term, fault-free operation. Suitable for AC installations with a voltage of 230 V and frequency of 50-60 Hz.

Key Features and Benefits

• D Characteristic: Provides delayed tripping in response to short-duration current surges—essential for protecting circuits with high inrush loads, preventing unnecessary tripping of the installation.
• Short-Circuit Capacity of 6 kA: Ensures effective disconnection during a short circuit, minimizing the risk of damage and fire.
• Flush-Mount Design: Enables aesthetic and discreet installation within walls.
• Expandability: Compatible with additional accessories (auxiliary contacts, trip units), allowing customization of the breaker’s functionality to meet specific installation requirements.
• Safety Compliance: Meets requirements of EN 60898-1 and EN 60947-2 standards, confirming compliance with the highest safety benchmarks.
• Durable Construction: Made from high-quality materials resistant to mechanical damage and environmental conditions.
• Protection Rating IP20: Protects against finger contact and ingress of solid objects larger than 12.5 mm—standard protection level for devices installed within enclosures.
• Rated Insulation Voltage Ui 500 V: Ensures safe operation in installations up to 500 V.
