300A BULLET 450046922 BREAKER

Manufacturer Part Number: 450046922

The 450046922 is a high-current, 300A three-pole bullet-style load circuit breaker designed for use in Infinity power distribution systems. Its plug-in configuration allows integration with compatible DC distribution panels, while the three-pole design provides coordinated protection for high-capacity distribution circuits. The breaker is intended for telecommunications and other high-power DC infrastructure where reliable load circuit protection is required.

Designed for high-current applications, the 450046922 occupies three circuit-breaker positions and requires conductors sized at a minimum of 4/0 AWG according to the applicable ordering guide. Because it is a three-pole breaker, the Infinity system requires the appropriate multi-pole adapter arrangement for proper installation and operation. The breaker is therefore suited to installations requiring high-capacity DC load protection within compatible Infinity power systems.
