WATSNA-63/3P 10A

series introduction

# Introduction to the WATSNA - 63/3P 10A Product Series

## 1. Overview
The WATSNA - 63/3P 10A product series is a high - performance electrical protection and control solution designed to meet the diverse needs of modern electrical systems. This series is engineered with precision and adheres to strict quality standards, making it a reliable choice for a wide range of applications in both industrial and commercial settings.

## 2. Key Specifications

### 2.1 Rated Current
The "10A" in the product model indicates its rated current. This means that the device is designed to handle a continuous current of 10 amperes under normal operating conditions. It is suitable for circuits where the load current typically does not exceed this value, ensuring stable and safe operation.

### 2.2 Pole Configuration
The "3P" stands for three - pole. A three - pole configuration is commonly used in three - phase electrical systems. In a three - phase setup, each pole is responsible for carrying one of the three phases of the electrical supply. This allows for the proper distribution and control of power in three - phase loads such as industrial motors, large - scale lighting systems, and some commercial equipment.

### 2.3 Breaking Capacity
The "63" in the model refers to the breaking capacity of the device, which is 63 kA (kiloamperes). Breaking capacity is a crucial parameter that indicates the maximum short - circuit current that the device can safely interrupt without being damaged. A high breaking capacity of 63 kA makes the WATSNA - 63/3P 10A suitable for use in electrical systems where there is a risk of high - magnitude short - circuits, providing reliable protection against electrical faults.

## 3. Product Features

### 3.1 Overcurrent Protection
The WATSNA - 63/3P 10A is equipped with advanced overcurrent protection mechanisms. It can detect when the current flowing through the circuit exceeds the rated 10A value. In case of an overcurrent situation, such as a short - circuit or an overload, the device will quickly trip and interrupt the circuit. This helps prevent damage to electrical equipment, reduces the risk of electrical fires, and ensures the safety of personnel working with the electrical system.

### 3.2 Thermal and Magnetic Tripping
It utilizes both thermal and magnetic tripping functions. The thermal tripping mechanism responds to long - term overloading conditions. When the current is slightly above the rated value for an extended period, the heat generated by the current causes a bimetallic strip to bend, which in turn triggers the tripping action. The magnetic tripping mechanism, on the other hand, is designed to respond rapidly to high - magnitude short - circuits. A large current flow creates a strong magnetic field that activates a solenoid, causing the device to trip almost instantaneously.

### 3.3 High - Quality Construction
The product is built with high - quality materials to ensure durability and reliability. The internal components are carefully selected and manufactured to withstand the rigors of continuous operation. The enclosure is designed to provide protection against dust, moisture, and mechanical damage, making it suitable for use in various environmental conditions.

### 3.4 Easy Installation and Maintenance
The WATSNA - 63/3P 10A is designed for easy installation. It has standardized mounting dimensions and connection terminals, which allows for quick and straightforward integration into existing electrical panels or new installations. Additionally, the device is designed for easy maintenance. In case of a fault or the need for inspection, the internal components can be accessed and replaced with relative ease, minimizing downtime.
