Many different devices are responsible for the safety of household and industrial electrical networks. But the most important ones are automatic machines, switches that can turn off on their own in case of short circuit or excessive load on a separate circuit. Properly selected circuit breakers will ensure the necessary safety, including fire safety.
Operating principle and main characteristics
Electrical appliances are produced by industry in a fairly wide range so that the consumer can choose it to suit their individual needs. Modern safety standards recommend creating a network of several separate circuits in an apartment, house, or workplace. So that in the event of a technical shutdown of one, the others can remain operational. The features of the machine include:
- They are triggered by overheating or due to an electromagnetic field.
- Can remain in a standby state indefinitely.
- Mechanical and electronic part designed for multiple operations.
- Most precisely tuned to a specific electrical load.
- Do not require maintenance or periodic repairs.
Important : the machine will fully perform the assigned task only if it is correctly selected according to all electronic and technical parameters. Installed in communications in the right place and additionally protected from adverse weather operating conditions. Including high humidity and large amounts of dust.
What to look for when choosing
Electrical equipment, manufactured in compliance with all applicable domestic and international standards, has strictly recommended operating conditions. Technical characteristics will allow you to select the required number of machines, taking into account the unique conditions of their operation. The following points are worth mentioning as universal recommendations regarding selection:
- what rated current the switch is designed for;
- automatic circuit breaker for direct or alternating current in the network;
- quantity connected poles in the product;
- how long it takes to operate;
- how many cycles the mechanism is designed for.
The last indicator can conditionally be called important, since the main task of the network component is to interrupt the supply of electric current to consumers in a timely manner. You can choose and buy a circuit breaker from a fairly wide range. Including choosing equipment for different needs for each individual circuit. Ensure maximum safety, protect consumers from internal short circuit and permanent breakdown.
