The ABB REA 107-AA is a window-type (bushing-type), cast resin insulated current transformer (CT) designed for measurement and protection purposes in medium-voltage (MV) switchgear and electrical installations. As a window-type CT, it has a central circular or rectangular opening through which the primary conductor (typically a busbar or cable) passes, serving as a single-turn primary winding. The cast resin insulation provides excellent mechanical strength, moisture resistance, and dielectric properties, making it suitable for indoor use in harsh environments.

The ABB VD4/CX refers to a medium-voltage, indoor, vacuum circuit breaker from ABB’s renowned VD4 family. The “/CX” suffix indicates a specific design series, often featuring enhanced safety, modularity, and advanced control options. The following codes detail its specific configuration, making it a fully defined circuit breaker ready for installation in switchgear panels (e.g., UniGear, ZS1).

The ABB HCFDACADANB2BAN21E is a modular, multi-channel actuator from the ABB i-bus® KNX product family, specifically belonging to the “System pro M” series of DIN-rail mounted devices. It is a configurable binary input and relay output module designed for building automation and control via the KNX/EIB standard.

The ABB GS251S C16/0.03 is a highly specialized, compact rotary switch-disconnector from the ABB System Pro M GS series. This specific configuration combines a 63A frame, 3-pole switch-disconnector with a front-mounted rotary handle (C16) and includes an integrated low-current fuse or protection element rated at 0.03A (30mA).

The ABB GS201 F C16 is a specific configuration of a rotary switch-disconnector (load break switch) from the ABB System Pro M compact GS series. This configuration combines a 32A frame, 3-pole disconnector with fuse holders (F) and a specific front-mounted rotary handle (C16), creating a compact switch-fuse unit.

The ABB GSH202 AC -C16/0.03 is a specific configuration of a high-performance AC power contactor from ABB's G-H series. This configuration combines a 200A frame, AC-operated contactor with a specific front-mounted rotary handle (-C16) and includes an integrated low-current fuse or protection element rated at 0.03A (30mA) for an auxiliary control circuit.

The ABB GSJ201 C32 is a compact, heavy-duty rotary switch-disconnector (isolator) from ABB's System Pro M GS range. It is designed for main isolation, load breaking, and emergency switching in industrial control panels and distribution boards, where a high breaking capacity and durability are required in a compact size.

The ABB GSH201 C40 is a heavy-duty, high-performance AC power contactor from ABB's G-H series, designed for demanding switching of three-phase AC loads, particularly motors, in industrial applications. The "C40" suffix specifically denotes a side-mounted, rotary manual operator with a lockable handle, allowing for local manual control and safe maintenance lockout.

The ABB GSN201L C10 is a compact, three-phase switch-fuse combination unit from ABB's System Pro M power distribution product range. It integrates a manual rotary switch-disconnector (isolator) with fuse holders into a single device, providing a safe means for circuit isolation, load switching, and short-circuit protection in a compact footprint.

The ABB GSH201-C20 is a high-performance, medium-duty AC power contactor from ABB's G-H series, designed for reliable switching of three-phase AC motors and other loads in industrial applications requiring robust construction and long electrical life.
