Types differential circuit breaker

Types of switches or differential circuit breaker
There are 2 basic types of differential circuit breaker:

Type AC

It is the standard type. Detects alternating leakage currents.
Type AC differentials not only do not detect earth leakage with a continuous component, but these currents can also block the differential if its direction is contrary to that of the relay. A Type A “HI” differential prevents this type of blockage.

Type A
This type of differential circuit breaker allows the detection of alternating or pulsating leakage currents with or without a continuous component.
Type A HIE RCDs are specially designed to function properly in harsh conditions or environments contaminated by aggressive agents and in electrically disturbed networks.
Aggressive environments are considered those places with the presence of: – Chlorine – Ozone – Sulfur – Nitrogen oxide – Sea salt – Dust – Humidity – Low or high temperatures.

Type B

The type B differential circuit breaker is made up of an independent part of the mains voltage, dedicated to the detection of sinusoidal AC currents and continuous pulsing currents of base frequency 50Hz, and another part dependent on the mains voltage dedicated to the detection of leak in a frequency range from 0Hz to 1MHz.

The type B differential ensures tripping as in type A differentials and also:
For sinusoidal alternating differential currents up to 1000Hz. • For pulsating continuous differential current.
For alternating differential current superimposed on a smoothed direct current.

For continuous pulsed differential current superimposed on a smoothed direct current.
For rectified pulsed continuous differential current resulting from two or more phases.
For smoothed continuous differential current

There are many types of differential circuit breakeres, classified by their operation, symbol, sensitivity and characteristics, in this store you can find all kinds of switches.

Differential circuit breaker prices

There is a wide variety of switches and their price will depend on their function and capacity, as well as the brand, as there are brands that have more value than others. Prices from 7 euros to 300 euros and more.

Differential circuit breaker sensitivity
RCDs that protect up to 300 milliamps (mA) are called high sensitivity. This device is very important to be placed in all electrical installations, both domestic and industrial, since it works in conjunction with the protective grounding conductor that must reach each plug or metal box, this is to disconnect the circuit as soon as there is any derivation.
Sensitivity: In accordance with the product standards UNE EN 61008 (pure differentials), UNE EN 61009 (differential blocks) and UNE EN 60947-2 (circuit breakers), the following standardized sensitivities are established: 6 mA, 10 mA, 30 mA , 100 mA, 300 mA, 500 mA, 1 A, 3 A, 10 A, 30 A • According to the mentioned standards, the differential must not trip below I Δ / 2, and must always trip above In
Firing time:
The average real trip time of a differential circuit breaker is 20 ms at IΔ

Characteristic of the differential circuit breakeres

The differential circuit breaker, which some call “life buoys” is a special electromechanical switch that, thanks to its internal devices, has the ability to detect the difference between the current absorbed by a consuming device and the return one. When this difference exceeds a value (generally 30 mA), the device interrupts the circuit, cutting off the current supply to the entire installation.

With the differential circuit breaker we can interrupt the supply of electrical energy when it is diverted to a person in an amount greater than 30 mA, preventing this current from increasing and endangering life. For this reason it is highly recommended to have it in all electrical installations, being mandatory in all new installations.

Direct contacts: acts as a complementary protection and does not exclude all other protections such as obstacles, coatings, insulating distances that must always be made.

Indirect contacts: It is an optimal solution since with a grounding of the metallic masses from 5 to 10ohms, with values of earth leakage current of 30mA, it interrupts the circuit. The electromagnetic type must be used, not the electronic one, which when the neutral is interrupted, does not act and leaves the entire installation polarized.
