Guardian, a revolution in electrical safety!

Electrical Safety You Can Trust

Electricity powers our homes and businesses, but what happens if there’s a fault on the electricity network supplying your property? Poor connections or breakages in the supply neutral conductor in TN or TT systems can cause excessive voltages, leading to premature equipment aging, increased energy consumption, or even catastrophic equipment failure—creating a real fire and safety risk.

A fault on the electricity network can result in:

• Overheating of electrical installations and appliances

• Premature equipment failure

• Serious damage or destruction of appliances

• Potential fire hazards

• Risk of electrocution

In TN systems, a broken neutral can expose anyone touching metallic parts—like bonded appliances or gas pipework—to dangerous voltages. Unfortunately, traditional protective devices such as MCBs and RCDs do not detect this fault and offer no protection.

Introducing the Guardian – A Revolution in Electrical Safety

The Guardian, incorporating our patented O-PEN® technology, is designed to continuously monitor your building’s electricity supply and infrastructure. Installed simply next to existing distribution boards, it detects faults and either safely isolates affected circuits or alerts the building owner.

The Guardian protects against:

• Loss of neutral

• Broken PEN conductor on TN-C-S supplies

• Voltage on protective earth/ground conductors

• High and low line voltages

• High and low frequency anomalies

It also connects to a cloud-based portal, enabling building owners and maintenance teams to remotely monitor the device and, if necessary, isolate connected loads. Alerts can be sent via SMS and email, warning of potential issues before they escalate into catastrophic failure.

Designed in the UK, the Guardian ensures and delivers peace of mind and cutting-edge safety for your electrical infrastructure.
