WATSNA-63/40 3CBR

series introduction

# Introduction to the WATSNA - 63/40 3CBR Product Series

## Overview
The WATSNA - 63/40 3CBR product series represents a cutting - edge solution in the field of electrical protection and control. Engineered with precision and innovation, this series is designed to meet the diverse and demanding requirements of modern electrical systems, offering reliable performance, advanced features, and long - term durability.

## Key Specifications
### Current Ratings
- The "63/40" in the product name indicates the current ratings. The series is capable of handling a maximum continuous current of 63 amperes, which makes it suitable for a wide range of medium - to high - power electrical applications. The 40 - ampere rating can be used in scenarios where a lower current capacity is sufficient, providing flexibility in system design.
### Circuit Breaker Type
The "3CBR" denotes that these are three - pole circuit breakers. Three - pole circuit breakers are commonly used in three - phase electrical systems. They are essential for protecting the electrical circuits from overcurrents, short - circuits, and other electrical faults in three - phase power distribution networks.

## Design and Construction
### Robust Enclosure
The WATSNA - 63/40 3CBR circuit breakers are housed in a high - quality, impact - resistant enclosure. This enclosure is designed to protect the internal components from environmental factors such as dust, moisture, and mechanical damage. It also provides electrical insulation, ensuring the safety of the operators and the integrity of the electrical system.
### High - Quality Internal Components
Inside the enclosure, the circuit breakers are equipped with high - performance contacts, trip units, and other essential components. The contacts are made of high - conductivity materials to minimize power losses and ensure reliable electrical connections. The trip units are designed to accurately detect overcurrents and short - circuits and quickly interrupt the circuit to prevent damage to the electrical equipment.

## Performance Features
### Overcurrent Protection
The WATSNA - 63/40 3CBR series offers excellent overcurrent protection. The trip units are calibrated to respond to different levels of overcurrent. In the event of a moderate overcurrent, the circuit breaker will trip after a certain time delay, allowing temporary overloads to pass without unnecessary interruptions. However, in the case of a severe overcurrent or a short - circuit, the circuit breaker will trip instantaneously to protect the system.
### Short - Circuit Protection
The circuit breakers are designed to handle high - magnitude short - circuit currents. They have a high short - circuit breaking capacity, which means they can safely interrupt the circuit during a short - circuit event without causing damage to themselves or the surrounding electrical equipment. This feature is crucial for maintaining the safety and reliability of the electrical system.
### Adjustable Trip Settings
Some models in the WATSNA - 63/40 3CBR series come with adjustable trip settings. This allows the users to customize the overcurrent and short - circuit protection according to the specific requirements of their electrical systems. For example, in a system with sensitive equipment, the trip settings can be adjusted to a lower value to provide more precise protection.

## Applications
### Industrial Applications
In industrial settings, the WATSNA - 63/40 3CBR series is widely used in three - phase power distribution panels, motor control centers, and other electrical equipment. It can protect motors, transformers, and other industrial machinery from electrical faults, ensuring the smooth operation of the production process.
### Commercial Buildings
In commercial buildings such as offices, shopping malls, and hotels, these circuit breakers are used in the electrical distribution systems to protect lighting, HVAC systems, and other electrical loads. They help to prevent electrical fires and equipment damage, providing a
