AMP Safe Pro and AMP Safe Pro Plus replacement trip units
OEM support for Masterpact M trip unit has been discontinued, making replacement parts difficult to source.
The AMP Safe Pro and AMP Safe Pro Plus are replacement trip units for the Masterpact STR trip and are fully compatible with Schneider/Merlin Gerin & Square D Masterpact M, MP, IEC and UL rated breakers.
These plug-in units have been designed and developed to mirror the Masterpact STR DINF function and design precisely. They are the only replacement units available to do so.
