With a 300 A current rating and a true 3‑pole design, this GE component delivers reliable overcurrent protection while ensuring all phases trip together for safer, more predictable fault response.\u003c\/p\u003e \u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCurrent rating:\u003c\/strong\u003e 300 A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 240 V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e CDK3300\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy the CDK3300 matters\u003c\/h3\u003e\n\u003cp\u003eIn three‑phase systems, a single‑phase protection can leave others exposed to imbalance and equipment stress. The CDK3300’s 3‑pole design ensures all phases disconnect in unison during a fault, reducing the risk of collateral damage to motors, drives, and feeders. Built to integrate smoothly with GE panels and the CDK product family, it offers consistent protection characteristics and straightforward sourcing for maintenance or replacements.\u003c\/p\u003e \u003ch3\u003eIdeal applications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eThree‑phase feeders powering large motors, pumps, and compressors\u003c\/li\u003e \u003cli\u003eMain disconnects in mid‑size commercial or light industrial distribution panels\u003c\/li\u003e \u003cli\u003ePower distribution for data centers, labs, and critical loads with stringent uptime requirements\u003c\/li\u003e \u003cli\u003eProtection for HVAC systems, industrial automation equipment, and process lines\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eInstallation and compatibility\u003c\/h3\u003e\n\u003cp\u003eEnsure you’re working with a GE‑compatible panel or distribution setup to maximize reliability and fit.
