The ABB 2TFC800-104R1001 is a soft starter designed to control the acceleration, deceleration, and operation of three-phase AC induction motors. It belongs to ABB's TFC series (also known as the Softstarter TFC or TFC Family), which is renowned for providing smooth, controlled starting and stopping of motors.

The ABB OTM100F4C10D380C is a 4‑pole motorized automatic transfer switch (ATS) / change‑over switch designed to automatically and manually transfer AC electrical loads between two independent power sources — typically the utility (mains) supply and a backup generator — in three‑phase low‑voltage distribution systems. It integrates a motorized operator for automatic switching based on control logic and supports manual override via a handle for maintenance or emergency use. The switch is engineered with mechanical interlocks that prevent the two sources from being connected simultaneously, improving safety and protecting connected equipment. It is suitable for use in commercial, industrial, and critical‑power applications where reliable continuity of supply is essential.

The ABB OTM315E4C10D380C is a fully featured Molded Case Circuit Breaker (MCCB) from ABB's advanced OTM series (previously known as the Tmax XT series). It is a high-performance, current-limiting air circuit breaker designed for reliable protection and control in industrial and commercial low-voltage electrical installations

The ABB OTM160E3C10D380C is a 3‑pole motorized automatic transfer switch (ATS) / change‑over switch designed to transfer electrical loads between two independent AC power sources — typically from the utility mains to a backup generator — in three‑phase low‑voltage power distribution systems. It is part of ABB’s range of motorized change‑over switches, which provide reliable automatic switching using a motorized operator as well as manual override via a handle. A mechanical interlock ensures that both power sources remain isolated and cannot be connected simultaneously, improving safety and system protection. The switch is suitable for industrial, commercial, and other environments where continuity of power and safe source change‑over are essential.

The ABB ATS021 is a compact automatic transfer switch (ATS) controller used in electrical power systems to manage and automate transfer between two power sources — typically a primary (normal) line and a secondary (emergency or generator) line. It continuously monitors the voltages of both power lines and, based on adjustable thresholds and delays, controls the opening and closing of associated circuit breakers to transfer loads when an anomaly (e.g., mains failure) is detected and to restore the original source when it returns. The unit supports both automatic operation and manual override and is suitable for a wide range of industrial and commercial installations requiring reliable automatic transfer performance.

ABB OTM_C10D is a compact automatic transfer switch (ATS) / motorized change‑over switch module designed for automatic or manual switching between two power sources in low‑voltage electrical systems. It is part of ABB’s OTM_C_D compact ATS product family, typically used in applications where continuity of supply between a normal (utility) source and an alternate (e.g., generator) source is required.

The ABB OTM100F4C21D380C is a 4‑pole motorized automatic transfer switch (ATS) / change‑over switch designed for automatic and manual switching of electrical loads between two independent AC power sources, such as the utility mains and a backup generator, in three‑phase low‑voltage distribution systems. It is part of ABB’s OTM_C_D automatic transfer switch family, which provides reliable open‑transition power source transfer using a motorized operator and supports manual override via a handle.

The ABB OTM125F4C21D380C is a 4‑pole motorized automatic transfer switch (ATS) / change‑over switch designed to automatically transfer electrical loads between two independent AC power sources — such as the utility mains and a standby generator — in three‑phase low‑voltage power distribution systems. This switch features a motorized operator for automatic source switching triggered by internal logic (C21D controller class) and also supports manual override via a handle or external control. A mechanical interlock ensures that the two sources remain electrically isolated and prevents them from being connected at the same time, enhancing safety and protecting equipment.

The ABB OMD800E480C is an automatic transfer switch controller designed to manage the automatic switching of electrical loads between two independent power sources (such as utility mains and a standby generator) in low‑voltage three‑phase systems. It serves as the intelligence and logic module for an automatic transfer switch (ATS), working with ABB motorized change‑over switches to perform safe and reliable source transfers.

The ABB OTM100F4C20D380C is a 4‑pole motorized automatic transfer switch (ATS) / change‑over switch designed to automatically and manually transfer electrical loads between two independent AC power sources — typically the utility mains and a backup generator — in three‑phase low‑voltage power distribution systems. This compact, robust device incorporates a motorized operator for automatic switching based on control logic and also supports manual override via a handle for maintenance or emergency operation. A mechanical interlock ensures that both power sources can never be connected at the same time, protecting equipment and enhancing safety during source transitions. The model’s “20D” designation indicates integrated control logic suitable for standard automatic transfer applications without needing a separate external controller.
