Abb SRPF250A225 Rating Plug 225 Amp Trip Unit

Product Description

The ABB SRPF250A225 is a 225-amp rating plug designed for use with compatible RMS1 series circuit breakers. Rating plugs set the maximum continuous current rating and trip threshold for the host breaker, allowing a single frame size to be field-configured for multiple ampacity levels. This plug is rated at 225 amps and is installed by licensed electricians performing panel upgrades, service entrance work, or breaker maintenance in commercial and industrial distribution systems.

Rating plugs of this type are used in low-voltage power distribution applications where a molded case circuit breaker must be calibrated to a specific continuous current rating. The SRPF250A225 fits the 250-amp frame class of the RMS1 breaker series, making it a common replacement or configuration component during switchgear servicing, load center upgrades, or breaker refurbishment in commercial facilities.

Key Features

• Sets continuous current trip rating at 225 amps for the host circuit breaker
• Designed for the RMS1 250-amp frame series
• Field-installable without replacing the entire breaker frame
• Allows one breaker frame to serve multiple ampacity configurations

Compatibility

Designed as an OEM-style rating plug for RMS1 series molded case circuit breakers in the 250-amp frame class.

Installation Notes
