The ABB S204‑C80 is a four‑pole miniature circuit breaker (MCB) from ABB’s S200 series designed to protect electrical circuits against overloads and short circuits in three‑phase systems. It uses a type C tripping characteristic which allows moderate inrush current (such as from motors and inductive loads) without nuisance tripping. The breaker is intended for DIN‑rail mounting in distribution boards and control panels where reliable protection and compact modular design are required.

The ABB AF305‑30‑11‑13 is a 3‑pole AC/DC contactor from the ABB AF‑series designed for motor control and power switching applications in industrial and commercial electrical systems. It features an electronically controlled coil that accepts a wide control voltage range, making it suitable for use with both AC and DC control supplies without needing different coils. The device includes three normally open main contacts and one auxiliary contact (1NO + 1NC) for control and signaling. With a block‑type design and built‑in surge suppression, this contactor is rugged and reliable for switching three‑phase motors and other heavy loads up to high voltages.

The ABB 1SDA054911R1 is an auxiliary contact block accessory designed to attach to compatible molded case circuit breakers (MCCBs) in the Tmax T series (frames T4, T5, and T6). It provides additional signaling and contact switching capability by offering multiple changeover contacts that reflect the breaker’s status and can be used for remote indication or control logic interlocking in electrical distribution and protection systems. This accessory is suitable for use with both AC and DC control voltages up to 250 V.

The ABB A260‑30‑11 is a three‑phase AC magnetic contactor designed for motor control and general power switching applications in industrial and commercial electrical systems. It is suitable for motor starting, isolation, bypass, and distribution switching of three‑phase loads. The contactor features a robust block‑type design with three main normally‑open contacts and built‑in auxiliary contacts (1 NO + 1 NC) for control and signaling purposes. It is intended for use up to 690 V AC with appropriate coil voltage (220–230 V AC / 230–240 V AC), and is commonly paired with overload relays in motor starter circuits.

The ABB BSR11 24 VDC is a safety/expansion relay from ABB’s Sentry series designed for use in machine safety and control circuits. It is intended to monitor safety devices such as emergency stop buttons and safety interlocks by integrating them into the relay’s supply circuit. The device can also be used as an expansion module to increase the number of safe relay outputs when connected to a primary safety relay or safety PLC. The relay is DIN‑rail mountable and uses screw terminals for secure connections.

The ABB S203‑C100 is a three‑pole miniature circuit breaker (MCB) designed for overload and short‑circuit protection of electrical circuits in residential, commercial, and light industrial installations. It features a type C tripping characteristic, making it suitable for circuits with moderate inrush currents such as lighting, small motors, and general power distribution. The breaker is intended for DIN‑rail mounting and can be used to safely interrupt fault currents while protecting conductors and connected equipment.

The ABB AF400‑30‑11 is a three‑pole AC contactor designed for heavy industrial motor control and power switching applications. It belongs to ABB’s AF contactor series with an electronically controlled coil that supports a wide control voltage range (100 – 250 V AC or DC), making it suitable for global installations without needing coil changes. The contactor is used to switch three‑phase motors, isolation and bypass circuits, and other industrial loads up to high voltages. It includes three normally open main contacts for the power circuit and one normally open plus one normally closed auxiliary contact for control, signaling, and interlocking functions. The block‑type design is robust and can be extended with auxiliary contact blocks and other accessories.

The ABB XT3N250 TMD250/2500 FF 4P is a four‑pole molded case circuit breaker (MCCB) from ABB’s Tmax XT series, designed for industrial and commercial power distribution protection. It provides combined thermal and magnetic protection to defend electrical circuits against overloads and short‑circuits. The four‑pole design (three phases plus neutral) with front terminals is suited for fixed installation in switchboards and distribution panels. Adjustable trip characteristics allow coordinated protection of three‑phase systems and neutral circuits.

The ABB CM‑PVS.41S is a three‑phase monitoring relay designed to monitor the health of a three‑phase electrical supply. It continuously checks for overvoltage, undervoltage, phase loss, and incorrect phase sequence in three‑phase systems with line‑to‑line voltages within a specific range. When a fault condition is detected, the relay changes the state of its output contacts to signal alarms or to disconnect loads for protection. It is mounted on a DIN rail and typically used in industrial control panels, motor protection systems, and automation circuits to ensure correct and safe operation of three‑phase equipment.

The ABB MS116‑20 is a manual motor starter / motor protection breaker designed to provide manual ON/OFF control and motor protection in industrial and commercial electrical systems. It combines a disconnect switch with overload, short‑circuit, and phase‑failure protection to safeguard motors and loads without the need for external fuses. The device has a trip‑free rotary handle with clear ON/OFF/TRIP indication and adjustable overload current setting to match the motor’s full‑load current within the 16–20 A range. It is suitable for both three‑phase and single‑phase applications and mounts on DIN rails or panel surfaces
