Siemens Reyrolle 7XG35 ReyArc Arc Protection Device

Siemens Reyrolle 7XG35 ReyArc Arc Protection Device Suppliers,Exporters in India

ARP IMPEX is a supplier and exporter of Siemens Reyrolle 7XG35 ReyArc Arc Protection Devices in India. We supply the 7XG35 range, compatible P1X optical sensors and related accessories for low-voltage and medium-voltage switchgear protection projects.

The Reyrolle 7XG35 detects the intense light produced by an internal arc fault and sends a high-speed trip command to the relevant circuit breaker. It is used in air-insulated switchgear where an arc inside the busbar, breaker or cable compartment can cause serious equipment damage and put operating personnel at risk.

Depending on the selected model, the device works with four or twelve optical sensor inputs. Siemens offers P1X point sensors for individual compartments and line sensors for larger areas such as busbar sections. The sensors connect to the 7XG35 through fibre-optic cables.

For straightforward schemes, tripping can be based on light detection alone. Versions with CT inputs can check for both arc light and overcurrent before issuing the trip. This dual-criteria arrangement helps avoid operation from harmless light sources while retaining fast response during a genuine electrical fault. Siemens specifies an operating time below 2 ms for light-only operation and below 7 ms when light and current are checked together.

The device supports up to four protection zones, allowing different switchgear sections to trip the appropriate local or upstream breaker. It can be installed in new switchgear or added to existing panels as an arc protection retrofit.

Buyers searching for a Siemens Reyrolle 7XG35 supplier in India, an arc flash protection relay exporter, or a high-speed arc detection device for MV switchgear can send the complete part number, panel arrangement and sensor requirement for quotation.

Available Siemens Reyrolle 7XG35 Versions

Siemens 7XG3551-1FA00-0AA0

This version provides four arc-flash detection sensor inputs. It is suitable for light-only arc protection schemes where separate current-check inputs are not required.

Siemens 7XG3552-1FA00-0AA0

This model provides four optical sensor inputs and four CT current inputs. It can operate using arc-light detection alone or a combination of light and overcurrent.

Siemens 7XG3553-1FA00-0AA0

This version provides twelve optical sensor inputs along with four CT inputs. It suits larger switchboards or projects where several compartments and protection zones must be monitored from one device.

Optical Sensor Options

P1X Point Sensors

Point sensors monitor a particular location inside the switchgear. They are commonly installed in cable compartments, circuit-breaker chambers, CT compartments and other enclosed sections where a local arc may occur.
Siemens lists point sensors with fibre-optic cable lengths from approximately 3 to 35 metres.

P1X Line Sensors

Line sensors monitor a wider area along the length of the sensor. They are suited to large busbar compartments or switchgear sections where one sensor must cover more than one enclosure.

The line-sensor element can cover lengths from approximately 5 to 40 metres. Point and line sensors can also be used together where the panel layout requires both local and wider-area detection.

Features

• Detects direct and reflected light produced by internal arc faults
• Sends a high-speed trip signal to reduce fault-clearing time
• Supports selective tripping through configurable protection zones
• Available with four or twelve optical sensor inputs
• P1X point and line sensors suit different switchgear compartments
• Optional current inputs support secure light-and-current tripping
• Four high-speed outputs can operate the required breaker circuits
• Continuous supervision checks the device, sensors and fibre connections
• Breaker failure supervision can initiate backup tripping
• Front LEDs provide clear zone, trip and alarm indication
• Event and fault records support investigation after operation
• Reydisp Evolution allows online and offline configuration
• USB-C access simplifies commissioning and settings transfer
• Wide-range AC/DC supply reduces voltage-specific variants
• Compact DIN-rail housing suits crowded control compartments
• Detachable terminals make panel wiring and replacement easier
• Suitable for new switchgear and existing panel retrofit projects

Applications

Siemens Reyrolle 7XG35 ReyArc devices are used for arc protection in:

• Medium-voltage air-insulated switchgear
• Low-voltage switchboards
• Busbar compartments
• Circuit-breaker compartments
• CT and metering chambers
• Cable termination compartments
• Incoming and outgoing feeder panels
• Bus-coupler and bus-section panels
• Motor control centres
• Utility distribution substations
• Industrial substations
• Power-generation plants
• Solar and wind power substations
• Oil and gas facilities
• Refineries and petrochemical plants
• Steel and cement plants
• Mining and mineral-processing sites
• Water and wastewater facilities
• Railway and infrastructure power systems
• Data-centre electrical distribution panels
• Existing switchgear arc-protection upgrades

The 7XG35 is particularly relevant for projects requiring an arc flash protection relay for MV switchgear, an optical arc detection device for busbar compartments, or a switchgear arc protection retrofit with point and line sensors. Siemens positions it for both new installations and retrofit upgrades.

Selecting the Correct 7XG35 Configuration

The device should be selected around the switchgear layout and required tripping scheme rather than only by the series name.

For an accurate quotation, provide:

• Complete Siemens part number, where available
• LV or MV switchgear application
• Number of panels and compartments
• Busbar, breaker, CT and cable-compartment layout
• Number of optical sensors required
• Point-sensor or line-sensor requirement
• Light-only or light-and-current operation
• CT ratio and secondary rating
• Number of protection zones
• Circuit-breakers to be tripped in each zone
