Service continuity

Ensuring service continuity has a direct impact on productivity indexes.

In industrial applications, it is very important to know how much energy is consumed in order to allocate costs to production processes. However, another aspect that is equally or more important is ensuring the continuity of the production process. An unexpected outage due to a tripped electrical protection can mean a high cost for the facility, directly affecting performance and process indicators.

The correct installation of residual current protection devices ensures both the protection of people and the continuity of service in industrial facilities, avoiding decreases in productivity indexes and economic losses due to production outages.

Safety

Choosing the wrong residual current protection can cause a blockage in the presence of a real leak, putting people and the components of the facility at risk, and causing unwanted trippings if the residual current is below the trip threshold.

Service continuity

Type-A residual current protection

Residual current protection devices designed to protect installations where there is a risk of AC current leakage and pulsing currents. This is the most common type of protection in industry, and is designed to protect lines with loads such as motors, resistive loads, LED lighting, compressors, HVAC systems or pumps without drive units.

Service continuity

Type-B residual current protection

Protective equipment designed to protect installations where there is a risk of DC current earth leakage or a combination of AC and DC current leakage.

Used as universal protection for loads such as speed or frequency drives, cold rooms, HVAC machinery, UPS and electric vehicle charging systems.

Type-B residual current protection

Type A and B residual current protection with automatic reclosing

These devices have a system that automatically reconnects residual current devices, avoiding human interaction and solving a problem caused by a one-time fault.

Type-b residual current protection

When is type-B residual current protection required?

Currently, many of the existing loads in industrial facilities use AC to DC converters, such as speed or frequency drives, cold rooms, automation and control systems, HVAC machinery, UPS, photovoltaic inverters or electric vehicle charging systems, where a leak can occur in the DC bus.

Type-B protection is the one required by the manufacturers of these components to ensure the smooth operation of the residual current protection, and guarantee that it is properly tripped in the event of earth leakage.

As mentioned previously, if these systems have the wrong protection devices, the result could be spurious trips, affecting production indexes.
Another important effect is the possibility of blinding, in which a real leak does not cause a trip, directly affecting the safety of the people or the physical components in the installation.

Safeguard your production and avoid unnecessary travel

A residual current protection trip can have a significant financial impact on any installation if the line or equipment being protected is not constantly monitored by maintenance managers. To ensure service continuity in these cases, it is essential to install devices that can reconnect automatically.

These devices have a system that automatically reconnects residual current devices, avoiding human interaction and solving a problem caused by a spurious fault. This avoids the need to dispatch a technician to the electrical panel to reset the device, saving time and money.

Circutor has a wide range of type-A and type-B solutions with automatic reclosing to guarantee the proper response to earth leakage at any time.
