Interference-Limiting Surge-Suppressing Straight-Blade Receptacles

Receptacles protect sensitive equipment from electromagnetic interference (EMI) and spikes in voltage. An isolated ground connection blocks EMI. The indicating light turns green when receptacles have power and are protected. A flashing red light and an audible alarm indicate power but no surge protection. When mated with a plug, receptacles provide an extra-tight fit to remain secure in high-vibration applications. Also known as hospital-grade receptacles. They fit standard GFCI wall plates (not included).

Also known as hospital-grade outlet strips, these outlets have an extra-tight fit to prevent plugs from detaching. They are marked with a green dot. A circuit breaker prevents damage from current overload and short circuits.

Surge suppression outlet strips protect against damage from voltage spikes. The surge rating indicates how much energy the outlet strip can absorb before it needs to be replaced.

Outlet covers protect outlets from dust when not in use.

Fasten mounting clips to a surface, and snap the channel on the back of outlet strips into the clips.
