Built for sensitive electronics

This Monoprice 135099 surge protector delivers 180 joules of protection against voltage spikes from lightning strikes, grid switching or large appliances cycling on and off. It suits home-office users and small-business setups that need basic defence for computers, routers and other microprocessor-based gear.

Metal housing and integrated breaker

A rugged steel enclosure resists impacts and wear better than typical plastic strips, making it suitable for workshops, garages or busy desk areas. Four grounded outlets accept standard plugs while the 15 amp resettable circuit breaker cuts power instantly during an overload, letting you restore service with a button press.

Passive thermal management

The all-metal case acts as a heatsink, dissipating warmth from the internal protection components without any fan noise. Power draw is limited to the 15 amp rating of the breaker, so connected devices stay within standard household circuit limits during normal operation.

Questions about this item

What surge-protection rating does the 135099 provide?

The 135099 delivers 180 joules of surge protection to absorb voltage spikes from lightning, grid switching or large appliances cycling on and off.

How much clearance does the metal housing need for mounting?

The rugged metal case has four keyhole slots on the back; allow enough wall or bench space for the 15 A unit plus its 6 ft cord to reach the outlet without tension.

How do I reset the protector after an overload trips the breaker?

Unplug connected devices, press the integrated 15 A resettable circuit breaker button until it clicks, then reconnect equipment — skipping the unplug step is the common mistake.
