The MV2 SPAM 150C (Retro�t) uses a vertical Motor vision (MV2) that is wired as per the original unit adopting the same terminal connections making this a direct pin for pin alternative. The replacement relay is mounted within a pre- wired chassis so no changes would need to be made to the panel aperture, a direct and fast �t solution minimalizing the downtime during on site installation.

The SPAM retro�t can be used to replace the ABB Spam 150C.The SPAM retro�t uses a vertically mounted Motorvision (MV2) protection relay complete with terminal adaptor assembly which converts the standard MV2 terminal connections to become pin for pin to the SPAM relay.The MV2 is mounted within an adaptor plate which simpli�es the installation and mechanical �t to the starter tray. Therefore, no wiring changes and no panel aperture changes are required. P&Bs SPAM retro�t is a direct and fast �t solution minimising the downtime during on site installation.
