Circuit breaker S 302 2P B 20A 6000A TX3 403388

Safety and reliability in your electrical installation

Overcurrent circuit breaker S 302 2P B 20A is a key element in protecting the electrical installation, protecting against the effects of overloads and short circuits. Designed for durability and ease of installation, it will work in both new and modernized installations. Two-pole design provides comprehensive circuit protection.

Functionality and technical parameters

This circuit breaker with B characteristic reacts quickly to current increase, which is especially important in circuits with receivers with high inrush current – such as motors or transformers. Rated current of 20A and short-circuit capacity up to 6kA at 400V (and 10kA at 230V) guarantee effective protection against damage. Mounting on a TH35 rail is standard, and the installation depth of 44mm allows installation in switchboards with limited space. Energy limitation class 3 indicates its ability to withstand short-circuit energy.

• Overload protection: Prevents damage to wires and devices caused by excessive load.
• Short-circuit protection: Immediate disconnection of the circuit in the event of a short circuit minimizes the risk of fire and equipment damage.
• B characteristic: Ideal for protecting circuits with receivers with high inrush current, such as motors or transformers.
• Flush mounting: Allows for aesthetic and discreet placement of the circuit breaker.
• Compliance with standards: Meets the requirements of EN 60898 and EN 60947 standards, ensuring safety and reliability.
• 2 module width: Compact dimensions allow for efficient use of space in the switchboard.

Construction and application

TX³ series circuit breakers are characterized by a solid construction and thoughtful design. The lower latch and terminal covers facilitate installation and connection of wires, saving installers time. The ability to cooperate with additional auxiliary equipment – such as auxiliary contacts or releases – expands the functionality of the circuit breaker and allows it to be adapted to the specific needs of the installation. Made of high-quality materials, it ensures long-lasting and trouble-free operation. Protection degree IP20 protects against finger contact and solid objects larger than 12.5 mm.
