ABB 60990 2-T003 Power Shield Solid State Trip Type SS

ABB Power Shield Solid State Trip Type SS is a solid-state overcurrent protection module used inside ABB low-voltage switchgear to provide fast, reliable tripping during overloads. It is offered in the 6099xx-T003 family with distinct current-range variants: 609901-T003 (50–225 A), 609902-T003 (250–600 A), 609907-T003 (300–800 A), 609903-T003 (600–1600 A), and 609904-T003 (800–2000 A). These trip devices are designed to pair with ABB Power Shield protection assemblies in both stationary and drawout operating mechanisms, and they work with other Power Shield components such as the 504 test set for functional verification. As a Type SS solid-state trip element, the Power Shield SS devices provide electronic overcurrent protection for ABB's low-voltage protection schemes, offering defined time-current characteristics that complement ABB's protection philosophy for distribution panels and switchgear.
