Guardian

Real-time site-wide monitoring with patented O-PEN® technology, detecting and isolating faults before they cause damage or injury.

Continuous protection for your entire site

Guardian is matt:e's flagship electrical safety device, incorporating patented O-PEN® technology to continuously monitor building electricity supplies and infrastructure.

Installed next to your existing distribution boards, it detects dangerous fault conditions that standard MCBs and RCDs simply cannot, then automatically isolates affected circuits or alerts building owners in real time.

A cloud-based monitoring portal lets building owners remotely manage connected loads and receive alerts via SMS and email.

One device, packaged to suit your site

The Guardian comes on four variant packages. Effective monitoring and protection to suit your needs:

Guardian TP The Guardian device on its own, for building into other manufacturers’ panel boards, feeder pillars and similar enclosures.
GES Guardian in an enclosure designed to sit next to distribution boards, able to control third-party contactors and relays where required.
GPC Guardian Protection Centre, rated to a maximum of 100A.
GPC-A Guardian Protection Centre for higher power loads, rated to a maximum of 1250A.

Why Traditional Protection Fails

Poor electrical connections are a hidden danger. Standard protective devices offer no defence against them.

Without Guardian

  • Overheating of installations and appliances
  • Premature equipment failure and damage
  • Fire hazards from undetected faults
  • Electrocution risk from live metalwork
  • MCBs and RCDs offer NO protection

With Guardian

  • Continuous real-time monitoring of all supplies
  • Instant fault detection and circuit isolation
  • Remote alerts via SMS and email
  • Cloud portal for remote load management
  • Full protection beyond standard devices
