3 A 1-Pole Bullet Load Circuit 407998137 Breaker

Manufacturer Part Number: 407998137

The 407998137 is a single-pole, 3 A bullet-style load circuit breaker designed for compatible telecommunications DC power distribution systems. It plugs into supported distribution panels, including compatible OmniOn Power Infinity series systems, to provide individual overcurrent protection for connected loads. Its compact plug-in design supports organized circuit protection in telecom racks, network equipment rooms, and power distribution shelves.

The breaker is designed for use in compatible panel assemblies rather than as a standalone household circuit breaker. It is listed as a load circuit breaker with an alarm function on mid-trip, allowing a compatible system to signal an abnormal trip condition. The manufacturer's ordering guide specifies a minimum wire gauge of 10 AWG for this 3 A model. Confirm the exact panel compatibility, voltage rating, and interrupting capacity before installation.
