Built for industrial power distribution, this 15A thermal-magnetic breaker offers robust overcurrent defense with fixed LI trip functions. It carries a Switching Duty (SWD) rating, making it suitable for switching 120V or 277V fluorescent lighting loads. Designed exclusively for Square D I-Line panelboards, the breaker utilizes a specialized jaw connection for secure phase bus mounting. It functions as a reliable substitute for FH34015 models and is superseded by the HDA36015 equivalent.Specifications

The FDA34015 is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes a specialized plug-on jaw connection that mounts directly to the I-Line phase bus.
What is the modern PowerPact replacement for the FDA34015?
