Information about VigiPacT RH99M Protection Relay 220 to 240 VAC 50/60/400Hz

The VigiPacT RH99M 220-240 V AC Protection Relay from Schneider Electric is an advanced solution for the protection of electrical installations, providing safety against earth leakage currents that can endanger people, equipment, and properties. This relay is designed for DIN rail mounting and is compatible with residential, commercial, and industrial electrical systems. It is ideal for protecting motors, distribution systems, and other critical loads, preventing electrical failures and fire risks due to earth leakages.

Technical Features:

  • Product Range: VigiPacT
  • Equipment Name: RH99M
  • Supply Voltage: 220-240 V AC (50/60/400 Hz)
  • Selectable Residual Current: 9 adjustable levels, from 30 mA to 30 A
  • Adjustable Delay Time: 9 settings, from instantaneous to 4.5 s
  • Type of Earth Leakage Protection: Type A (detection of alternating and pulsating current)
  • Maximum System Monitored Voltage: Up to 1000 V AC at 50/60/400 Hz
  • Installation: DIN rail mounting
  • Protection Rating: IP40 at the front

The VigiPacT RH99M relay continuously measures the earth leakage current in the electrical installation using an associated toroid. If the preset residual current value is exceeded, the relay trips the associated breaker to disconnect the installation, preventing possible damage and protecting people and equipment.

Additional Features:

  • Adjustable Sensitivity: This relay offers 9 sensitivity levels, allowing it to be adjusted between 30 mA and 30 A, catering to different protection needs. This makes it suitable for applications requiring high sensitivity, such as personal protection, as well as industrial applications handling larger currents.
  • Configurable Response Time: The delay time can be configured in 9 levels, from an instantaneous response to a maximum delay of 4.5 seconds, allowing customisation of protection for different scenarios and applications.
  • Compatibility with Toroidal Sensors: The relay is compatible with VigiPacT TOA, A and L current sensors, which measure earth leakage currents. These sensors must be installed in the installation to detect any current leakage and ensure the relay operates efficiently.

Additional Specifications:

  • Thermal Capability: 8 A conventional thermal current in the enclosure
  • Impulse Withstand Voltage (Uimp): 8 kV, ensuring the relay can withstand transient voltage spikes without being affected.
  • Overvoltage Category: Compatible with TT, TN-S and IT systems, ensuring its flexibility to adapt to different earthing configurations.
  • Measurement Type: Internal measurement of earth leakage currents in the range of 80% to 100%.
  • Terminal Compatibility: Screw connections for flexible and rigid cables with sections up to 2.5 mm², enabling safe and efficient installation.
  • Test and Reset Function: Includes the possibility for local and remote system tests to verify correct operation, as well as a manual reset function.

Design and Ease of Installation:

The VigiPacT RH99M relay is designed for DIN rail installation, facilitating its integration into existing electrical panels. With a compact size of 54 mm width, 81 mm height, and 74 mm depth, this device is easy to mount without taking up much space in the electrical panel. Additionally, its robust construction features an IP40 protection rating at the front and IP20 at the connections, making it suitable for a wide range of environments.

Applications:

The VigiPacT RH99M is suitable for various applications, including:

  • Personal Protection: Its adjustable sensitivity allows it to protect users from electric shocks due to direct or indirect contact.
  • Motor and Equipment Protection: It is ideal for preventing damage to motors and other electrical equipment due to earth leakage currents.
  • Electrical Distribution Systems: Protects electrical installations from fire risks caused by leakage currents in distribution systems.

Additional Benefits:

  • Compatibility with systems up to 1000 V AC, ensuring its capability to monitor high voltage installations.
  • Advanced protection against overvoltages and transients with resistance to voltage spikes up to 8 kV.
  • Certifications and Standards: The product complies with EN/IEC 60947-2 (Annex M), EN/IEC 60755, UL 1053, and CAN/CSA C22.2 No. 144 standards, ensuring its adherence to international safety and reliability standards.

The VigiPacT RH99M 220-240 V AC Protection Relay from Schneider Electric is a versatile and reliable solution for protecting people, properties, and equipment against earth leakage currents. With its adjustable sensitivity and response time, compact DIN rail mount design, and capability to operate in systems up to 1000 V AC, this relay is ideal for a wide range of industrial and commercial applications requiring advanced earth leakage protection.
