Direct plug-in surge suppressor

The Tripp Lite Ultrablok Isobar plugs straight into a wall outlet and provides two NEMA 5-15R sockets for connected equipment. A 1410 joule rating absorbs transient spikes before they reach sensitive electronics. Diagnostic LEDs confirm active protection and wiring status at a glance. The all-metal housing resists impact in busy environments.

120 V 15 A circuit limits

The unit operates on 110–125 V mains and passes up to 15 A or 1800 W to attached devices. A resettable 15 A breaker interrupts overloads without requiring fuse replacement. Clamping voltage is 140 V RMS across full normal and common mode paths. EMI/RFI filtering reduces line noise by 40–80 dB to prevent data errors.

Metal cabinet with direct mounting

The black metal enclosure measures 4.00" x 2.50" x 2.50" and weighs .8 lb, so it stays secure on the receptacle without sagging. Direct plug-in design leaves no cord to route or trip over. Two isolated filter banks keep noise from one device from coupling into the other. Build quality suits permanent installation in offices or workshops.
