Abb GTP0400U0410 Rating Plug 400A Gtu Series

Product Description

The ABB GTP0400U0410 is a 400-amp rating plug designed for use with ABB GTU series circuit breakers. Rating plugs set the continuous current rating of a molded-case circuit breaker, allowing a single breaker frame to be field-configured for multiple ampacity levels. This plug locks into the breaker's trip unit to establish the maximum continuous current the breaker will carry before initiating a trip event. Installation is performed by licensed electricians during initial commissioning or when adjusting system protection settings.

This rating plug is sized for 400-amp applications within the ABB GTU breaker series. It is used in commercial and industrial electrical distribution systems where molded-case circuit breakers require precise overcurrent protection calibration. Electricians select the appropriate rating plug based on the load requirement and the breaker frame's available rating range. Proper plug selection is a critical step in coordinating the overcurrent protection scheme for the distribution system.

Key Features

• 400-amp continuous current rating for GTU series breaker frames
• Allows field adjustment of breaker ampacity without replacing the full breaker
• Designed to interface directly with the GTU trip unit assembly
• Supports accurate overcurrent protection coordination in distribution systems
• OEM-style replacement for maintaining original breaker specifications

Compatibility

Designed for use with ABB GTU series molded-case circuit breakers requiring a 400-amp rating plug configuration.

Installation Notes

Installation must be performed by a qualified, licensed electrician. De-energize and lock out the circuit breaker and associated panel before handling any internal breaker components, following NFPA 70E arc flash and lockout/tagout procedures. The rating plug must be fully seated and secured in the trip unit before the breaker is returned to service. Verify the installed rating against the system's overcurrent coordination study before energizing.
