Product FAQs
6 answersWhat panelboards are compatible with the FGN36DB400 circuit breaker?
This breaker is engineered for integration into GE Record Plus Panelboards, GE Evolution Series Panelboards, and standard commercial switchboards. Its bolt-on mounting design provides a secure, vibration-resistant connection suitable for heavy industrial environments.
Can I adjust the trip settings on the FGN36DB400?
Yes, the integrated trip unit features adjustable Long-Time (L) and Instantaneous (I) functions. This allows panel builders and electricians to fine-tune the protection curve for selective coordination with upstream and downstream devices.
Are lugs included with this GE Record Plus breaker?
Yes, the FGN36DB400 comes equipped with lug terminals. When installing, always verify the conductor material and apply the manufacturer-specified torque to prevent thermal issues under load.
Why is the FGN36DB400 listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions, meaning this breaker may ship with either ABB or General Electric branding. The physical dimensions, mounting hardware, and FGN36DB400 catalog number remain identical for direct replacements.
What applications require the high interrupting capacity of the FGN36DB400?
With an interrupting rating of 65kAIC at 480V and 100kAIC at 240V, this breaker safely clears massive fault currents. It is designed for commercial facilities and service entrances where high available fault current requires robust arc flash and equipment protection.
Can the FGN36DB400 be installed in 600V AC systems?
Yes, this breaker is fully rated for 600VAC applications, providing a 25kAIC interrupting capacity at that voltage. It is suitable for heavy commercial and industrial power distribution networks.
