Seven-outlet surge protector

The Tripp Lite TLP74R provides seven NEMA 5-15R receptacles for desktop computers, monitors and peripherals. Six right-angle outlets and one transformer-spaced outlet accommodate bulky power bricks without blocking adjacent sockets. A lighted on/off switch with integrated circuit breaker controls power to all outlets.

1080-joule suppression limit

The unit absorbs up to 1080 joules of surge energy across full normal mode and common mode paths. Clamping voltage is 150 volts RMS and the suppressor meets UL 1449 3rd Edition, UL 1363 and IEEE 587 category A&B specifications. Protection is rated for 120-volt circuits between 110 and 125 volts.

Four-foot cord and slim profile

A 4.0-foot input cable with a standard NEMA 5-15P plug reaches nearby wall outlets without excess slack. The housing measures 1.33 by 2.04 by 12.4 inches and weighs 1.04 pounds, allowing horizontal or vertical mounting on a desk or wall. RoHS-compliant construction and a lifetime limited warranty back the hardware.

Questions about this item

Which outlet arrangement suits a power strip with six right-angle sockets and one transformer-spaced outlet?

The unit provides seven NEMA 5-15R receptacles: six right-angle outlets for standard plugs and one wider-spaced outlet that accommodates bulky transformer blocks without blocking neighbours.

What does the 1080-joule rating mean for daily protection?

It indicates the total energy the suppressor can absorb before its protective components degrade; 1080 joules is suitable for desktop PCs, monitors and networking gear in typical office or home environments.

How does the 150-volt RMS clamping voltage limit spikes on a 120-volt circuit?

When a transient exceeds 150 volts RMS, the suppressor diverts the excess to ground, capping the voltage that reaches connected equipment and reducing stress on sensitive power supplies.
