About Circuit Protection

At Zoro, we pride ourselves on offering a broad selection of top-grade Panelboards and Load Centers. These essential electrical components are meticulously designed to distribute and manage power in residential, commercial, and industrial settings. Our product line includes a variety of load centers, such as main breaker load centers, main lug load centers, sub-panel load centers, and different types of panel boards, including lighting panel boards and power distribution panel boards.

A Wide Array of Load Centers & Fuses

Our collection comprises diverse types of electrical load centers tailored to meet the unique needs of various industries. From simple household applications to complex industrial processes, our offerings include single-phase load centers for residential and three-phase load centers for commercial or industrial uses. Moreover, we also provide an array of load center fuses designed to protect your electrical circuits from overloads and short circuits.

Quality Panel Boards

We understand that a high-quality panel board is the backbone of any reliable electrical system. Hence, we offer an extensive range of robustly constructed electrical panel boards suitable for surface and flush mounting (panel board wall). Our selection ranges from small circuit breaker panels ideal for home use to large-scale switchgear panels designed for heavy-duty industrial applications.

How Are Load Centers & Panel Boards Made?

The manufacturing process for our panelboards and load centers involves careful planning and precise engineering. High-quality metal casings are typically used to house these units due to their durability and resistance against environmental factors. Inside these casings are circuit breakers or fuses attached to bus bars, facilitating electricity distribution across various circuits.

Tips on Using Load Centers & Panel Boards

While installing or using our panel boards and load centers, safety should always be your top priority. Ensure that a qualified professional performs all electrical work. Always turn off the main power supply before performing maintenance or installation. Lastly, regularly inspect your load center and panel board for signs of wear and tear to prevent potential issues.
