APC SurgeArrest PM5-UK - Reliable Power Surge Protection for Computers, Projectors and Electronics. 

The APC SurgeArrest PM5-UK provides 918 Joules of surge energy protection to safeguard sensitive electronics from voltage spikes, lightning-induced surges, and power fluctuations.Core Protection Features

Surge Energy Dissipation: Absorbs up to 918 Joules of excess energy, diverting harmful voltage spikes away from your connected equipment.

EMI and RFI Noise Filtering: Reduces electromagnetic and radio frequency line noise that can cause data loss, system errors, or keyboard lockups.

Fail-Safe / Catastrophic Event Protection: Uses internal components like thermal fuses and MOVs (Metal Oxide Varistors) to react instantly to severe strikes. If the circuitry is compromised by a heavy spike, the unit disconnects power entirely to ensure excess voltage never reaches your devices.

Safety Shutters: Features physical shutters on the 5 British (BS1363) outlets to prevent accidental object insertion.

Status Indicators

Protection Working LED: Warns you if the internal circuitry has taken a heavy hit and can no longer provide 100% protection, signaling that the unit needs replacement.

The APC Essential SurgeArrest PM5-UK protects against lightning-induced power surges.

How It Protects Against Lightning

Surge Absorption: It features a 918-Joule energy rating, meaning it can absorb high-energy electrical disturbances caused by nearby lightning strikes or power fluctuations before they reach your gear.

Instant Reaction: Internal components like metal oxide varistors (MOVs) and a thermal fuse react instantly to sudden, dramatic voltage spikes.

Fail-Safe Mechanism: If a heavy strike damages the internal circuitry, fail-safe technology permanently disconnects power from your equipment so excess energy cannot pass through.
