This surge suppressor is designed to provide safe, reliable surge protection in harsh environments. A 900-joule rating can protect connected equipment against even the strongest surges. Six outlets protect connected equipment against damaging surges, spikes and line noise. Convenient transformer outlets accommodate multiple transformers without blocking other outlets. A six-foot (1.8-meter) grounded cord reaches distant outlets. A lighted on/off switch with integrated circuit breaker provides power control over connected equipment. Breaker protects against dangerous system overload. Protected LED confirms that connected equipment is being protected. Four safety covers shield unused outlets from debris and accidental contact. A rugged metal case stands up to the harshest environments. Integrated keyhole slots on bottom panel provide convenient wall/desk mounting. As an added safety feature, the surge suppressor's bright yellow color alerts you and others that power cords and tools are in use.
