3NA3260

Updated: 2026-09-17

Overview

The 3NA3260 is a compact circuit breaker designed for industrial and commercial applications. It provides reliable protection against overloads and short circuits, ensuring the safety of electrical systems. Known for its high breaking capacity, the 3NA3260 is widely used in distribution boards and control panels. Its robust construction and ease of installation make it a preferred choice for engineers and electricians.

Structure and Working Principle

The 3NA3260 consists of a thermoplastic housing, metal contacts, and a tripping mechanism. When an overload or short circuit occurs, the tripping mechanism activates, interrupting the current flow. The breaker's design ensures quick response to faults, minimizing damage to connected equipment. Its modular construction allows for easy integration into existing electrical systems.

Key Features

The 3NA3260 offers several advantages, including a high breaking capacity of up to 10kA. This ensures reliable protection even under extreme conditions. Its compact size saves space in electrical panels, while the clear trip indication helps in quick fault diagnosis. The breaker is also designed for low power loss, enhancing energy efficiency.

Application Areas

The 3NA3260 is commonly used in industrial plants, commercial buildings, and infrastructure projects. It is suitable for protecting motors, transformers, and other electrical loads. In addition, it finds applications in renewable energy systems, such as solar and wind power installations, where reliable circuit protection is critical.

Maintenance and Precautions

Regular inspection of the 3NA3260 is recommended to ensure proper functioning. Check for signs of wear, overheating, or damage to the contacts. Always follow the manufacturer's guidelines for installation and maintenance. Avoid exposing the breaker to excessive moisture or dust, as this can affect its performance.

B2B Procurement Guide

When procuring the 3NA3260, verify the specifications to match your application requirements. Key factors include voltage rating, current capacity, and environmental conditions. Purchase from reputable suppliers to ensure product authenticity and quality. Bulk orders may qualify for discounts, so negotiate with suppliers for the best pricing.
