ECB24015G3 - 15 Amp Circuit Breaker

ECB24015G3 -  15 Amp Circuit Breaker

If you're working with a PowerLink™ Intelligent Panelboard and need a breaker that fits right in without second-guessing compatibility, the ECB24015G3 PowerLink™ Circuit Breaker is built for exactly that purpose. This 15 amp, 2-pole thermal-magnetic breaker is commonly used in commercial and industrial environments where maintaining the original system layout and performance matters. It’s designed to match the form, fit, and function of existing PowerLink™ setups, making it a practical choice for replacements or ongoing maintenance.

Operating at 480Y/277 VAC, this breaker uses a thermal-magnetic trip mechanism to respond to both overloads and short circuits, helping protect wiring and connected equipment within properly designed systems. It’s also HACR rated, which makes it suitable for HVAC-related applications, and includes HID and switching duty ratings for use in approved lighting and switching circuits. When installed in compatible PowerLink™ systems, it can support either manual or automatic reset functions, depending on how the system is configured—giving facility teams flexibility in how they manage power distribution.
