Built for everyday panelwork, this 20 A, 240 V device fits straight into BR-type panelboards and load centers, delivering solid protection where it matters most. The BR320ST isn’t just a breaker—it’s a smart, maintainable solution for teams that need dependable parts with a direct fit.\u003c\/p\u003e \u003ch3\u003eKey features that matter in the field\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eType BR, Plug-On design:\u003c\/strong\u003e Fast, tool-free installation into compatible distribution panels for streamlined maintenance and upgrades.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eThree-pole configuration:\u003c\/strong\u003e Provides balanced protection across all phases in 240 V systems, reducing the risk of imbalanced loads.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e20 A rating:\u003c\/strong\u003e Ideal for general circuit protection in commercial and light industrial applications where reliable fault interruption is essential.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eShunt Trip:\u003c\/strong\u003e Remote-trip capability adds an extra layer of safety, enabling controlled shutdown from a separate control or safety system when required.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart Number BR320ST:\u003c\/strong\u003e Clear, direct part-number matching ensures you get the exact device you need for a precise fit and compatibility.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy this breaker stands out\u003c\/h3\u003e\n\u003cp\u003eIn busy maintenance environments, compatibility and speed matter. The BR320ST is specifically chosen for its plug-on compatibility with BR-type panels, which minimizes downtime during service calls and panel upgrades. The shunt-trip feature is a practical safety enhancement for facilities that require remote or automatic disconnection in response to alarms, interlocks, or control signals. With a robust three-pole design, it handles the demands of 240-volt distribution without compromising protection, giving technicians peace of mind that the circuit will trip cleanly when a fault or safety condition arises.\u003c\/p\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003ePanelboard and load center deployments in commercial buildings, data centers, and light industrial setups.\u003c\/li\u003e \u003cli\u003eRemote safety strategies where a control system must trigger an immediate shutdown of specific circuits.\u003c\/li\u003e \u003cli\u003eSpare inventory for maintenance teams and panel builders who need a reliable, order-ready part with a direct fit.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePractical considerations\u003c\/h3\u003e\n\u003cp\u003eWhen selecting the BR320ST, verify that your panel supports Type BR breakers and that the application calls for a 3-pole 20 A 240 V device. The plug-on design simplifies installation, while the shunt-trip option provides optional remote disconnection capabilities.
