Surge suppression for office and home electronics

The Tripp Lite ISOBAR4 provides four NEMA 5-15R outlets rated for 120V AC input with a 3300 joule suppression rating. It delivers up to 1440 watts through a 6 ft cord with an angled plug. Two isolated filter banks use toroidal chokes and metal oxide varistors to reduce EMI/RFI interference between connected devices.

Behaviour during extended surges and noise events

The 3300 joule rating and 85000 amp surge current capacity absorb repeated transient spikes without degrading protection. Isolated filter banks prevent noise from one peripheral affecting another during continuous operation. The 12 amp circuit breaker resets after overload events to maintain power to remaining equipment.

Metal housing with keyhole mounting and safety

All-metal construction resists impact in busy environments. Keyhole slots allow wall or under-desk mounting to keep cords organised. Widely spaced outlets accept two large transformer plugs side by side. Four outlet safety covers protect unused ports from dust and accidental contact.

Questions about this item

Does the ISOBAR4 generate any heat or noise when it runs continuously?

The ISOBAR4 is a passive surge suppressor with no fan or active components, so it operates silently and produces no measurable heat during normal use.

What type of wall outlet and voltage does the ISOBAR4 require to function?

It needs a standard NEMA 5-15R wall receptacle supplying 120 V AC; the attached 6 ft cord ends in an angled NEMA 5-15P plug.

Will the ISOBAR4’s two isolated filter banks interfere with older transformer-style plug packs I still use?

The widely spaced NEMA 5-15R outlets accept up to two large transformer plugs side by side without blocking adjacent sockets.
