TJL4V2604 - 400Amp Circuit Breaker

TJL4V2604 - 400 Amp Circuit Breaker

The TJL4V2604 circuit breaker is a solid fit for your commercial and industrial electrical systems that need dependable circuit protection without changing existing equipment layouts. With a 400 amp rating and 3-pole configuration, this breaker is commonly used in three-phase power distribution systems, including switchboards, panelboards, and motor control equipment operating up to 600VAC.

In many facilities, keeping older systems running efficiently means finding replacement components that match the original setup correctly. The TJL4V2604 is designed for that kind of application, helping maintenance teams replace worn or damaged breakers while keeping the same form and fit already in place. Its interrupting capacity ratings — 65kA at 600VAC and 480VAC, plus 100kA at 240VAC — make it suitable for systems where reliable fault protection is required every day.

The compact footprint can also help when working inside existing electrical gear where space is limited. Whether it’s installed in a manufacturing plant, commercial facility, or industrial distribution system, the TJL4V2604 is built for long-term use and consistent operation in demanding environments.
