Overview
The Eaton Tripp Lite TLM446USBB Protect It! is a 4-outlet surge protector with a durable metal housing and four USB-A charging ports. It provides 450 joules of AC surge suppression for compatible 120V equipment while also filtering EMI/RFI line noise. A 6-foot power cord, integrated 15A resettable circuit breaker, illuminated power switch, and diagnostic LED provide additional functionality for home, office, retail, and workstation installations.
AC Power and Surge Protection
The TLM446USBB provides four NEMA 5-15R AC outlets for connecting compatible 120V equipment. Its surge suppression circuitry is rated at 450 joules and protects against power surges and spikes in normal-mode and common-mode configurations. The unit has a 15A electrical rating and is designed for a recommended 120V service.
USB Charging
Four USB-A charging ports are integrated into the surge protector for charging compatible phones, tablets, Amazon Kindle devices, and other USB-powered mobile equipment. The four USB ports share a total charging capacity of 4.2A. The 4.2A figure is a combined allocation for the USB charging ports rather than 4.2A available independently from each port.
Noise Filtering
Integrated EMI/RFI filtering helps reduce electromagnetic and radio-frequency interference on the AC line. The filtering is intended to reduce disruptive line noise that can affect connected electronic equipment.
Construction and Controls
The TLM446USBB uses a metal housing and has a single row of four AC outlets. A combination illuminated red power switch and 15A circuit breaker provides power control and overload protection. A diagnostic LED indicates the status of the surge protection circuitry.
Key Features
- Four NEMA 5-15R AC outlets for compatible 120V equipment
- Four USB-A charging ports with 4.2A total shared charging capacity
- 450-joule AC surge suppression with less than 1 ns response time
- Metal housing with EMI/RFI line-noise filtering
- 6-foot 14 AWG SJT power cord with NEMA 5-15P plug and integrated 15A circuit breaker
Applications
The TLM446USBB is intended for installations requiring a small number of protected AC connections together with convenient USB charging. Suitable applications include home and office workstations, retail counters, shared work areas, computer and peripheral setups, and other locations using compatible 120V electronics.
DC Supplies Product Note
The four USB-A ports have a combined 4.2A charging allocation, so the available USB charging current is shared when multiple devices are connected. The model is also distinguished from plastic-housing surge strips by its metal enclosure, making the housing construction an important consideration when selecting this particular model.
