## Summary description

Rittal 7979.722 is a black PDU surge protector designed for electrical installations requiring nominal current up to 19 A. It provides overvoltage protection for connected equipment, suitable for racks, enclosures and industrial control systems. Compact form factor and durable housing make it practical for server rooms, network cabinets and industrial cabinets.

## Long description

Rittal 7979.722 is a compact black PDU surge protector designed to provide type-3 overvoltage protection for terminal equipment. Intended for installation on enclosure frames in racks, network cabinets and industrial control systems, the unit supports a nominal current up to 19 A and is prepared for use in typical TN-S power networks. It features a durable housing, plug-in protective modules and an alarm contact for remote status indication.
Advantages
The module offers a fully wired overvoltage protection solution that is ready to connect and use immediately. Its compact and maintenance-friendly design allows arresters to be replaced without interrupting the power supply, and optical status monitoring on the arrester provides quick local verification. A floating alarm contact enables integration with building management or monitoring systems for remote fault indication.
Suitable for
Protection of terminal equipment in server rooms and network cabinets
Use inside industrial cabinets and control enclosures
Final-stage (type 3) surge protection in multi-stage overvoltage protection chains
Installations that require compact, enclosure-mounted surge protection with alarm output
When it may not be suitable
This product is designed as the third or final stage in an overvoltage protection concept and therefore is not a substitute for type 1 or type 2 main protective devices required in building installations or supply distribution systems. It is specified for a nominal current up to 19 A; installations that require higher continuous current ratings or primary lightning protection should use appropriately rated upstream devices.
Key specifications
Nominal current: up to 19 A
Colour: black
Protection stage: Type 3 (final-stage) overvoltage protection
Mounting: enclosure/frame mounting suitable for racks and cabinets
Network compatibility: ready to use on TN-S networks
Connection paths: L/N and N/PE
Status signalling: optical status indicator and floating alarm contact
Design: compact housing with plug-in protective modules for tool-free replacement
How to use
Mount the unit on the enclosure frame in the intended cabinet or rack location and connect supply conductors according to the specified L/N and N/PE paths. Ensure that appropriate upstream overvoltage protection (type 1 or type 2) is present in the installation as required for your site. After connection, verify optical status indicator and, if applicable, wire the floating alarm contact to your building management or monitoring system to receive remote status signals. Replace plug-in arresters when indicated by the status indicator or alarm without interrupting the protected circuit.
What to consider before purchase
Confirm that your installation already includes upstream type 1 or type 2 overvoltage protection where required
Verify that the nominal current rating (up to 19 A) matches the protected circuit requirements
Ensure compatibility with TN-S network topology in your facility
Check available mounting space on the enclosure frame for the compact module
Plan wiring for the floating alarm contact if remote monitoring is needed
Usage recommendations
Use this Rittal PDU surge protector as the final protection stage for sensitive terminal equipment. Combine it with appropriate upstream protective devices, perform periodic status checks of the optical indicator, and integrate the alarm contact into your monitoring system to maintain visibility of protection health.
