The ABB UA95‑30‑11 (Part Number 1SFL431022R8011) is a 3‑pole electrical contactor specially designed for capacitor switching and power factor correction applications. Unlike standard motor contactors, this unit is optimized to handle the unique electrical stresses of switching capacitive loads, providing reliable operation in Automatic Power Factor Correction (APFC) panels and similar systems. The contactor is suitable for industrial and commercial installations where switching of capacitor banks is required, and it supports AC control voltages around 220–230 V AC (50 Hz) / 230–240 V AC (60 Hz).

The ABB F204 AC‑63/0.03 is a 4‑pole residual current circuit breaker (RCCB) designed to protect people and installations from earth leakage (ground fault) currents in three‑phase AC electrical systems. It continuously monitors the balance of current in all conductors and trips the circuit when leakage current exceeds the specified threshold (30 mA), which helps prevent electric shock and fire hazards. This device does not provide overcurrent protection and should be used in combination with upstream protective devices such as MCBs or fuses. It mounts on a standard DIN rail in distribution boards or control panels and is suitable for residential, commercial, and light industrial installations under appropriate standards.

The ABB 1SAZ321201R2003 is a TA75DU‑42M thermal overload relay designed to protect three‑phase motors and electrical equipment from overload and phase fault conditions. This electromechanical device is mounted in series with a contactor and continuously monitors the motor load. When the current exceeds the set range or a phase failure occurs, the relay trips to disconnect the motor, helping prevent damage. It features adjustable current setting, temperature compensation, and both trip and signal contacts for control or indication circuits, and can be configured for manual or automatic reset depending on application needs.

The ABB F204 AC‑80/0.03 is a 4‑pole residual current device rated 80 A and 30 mA leakage sensitivity, suitable for three‑phase AC electrical systems. It provides earth leakage (ground fault) protection by disconnecting circuits when leakage current exceeds the threshold, safeguarding people and electrical installations from shock and leakage faults. It’s designed for DIN‑rail installation and typical distribution board use.

The ABB AL40‑30‑10 24VDC contactor is a 3‑pole DC control contactor used for switching moderate three‑phase loads, especially where a 24 V DC coil is required. It supports typical AC load duties and integrates easily with PLC/DC logic systems, offering auxiliary contact feedback and robust mechanical performance for industrial control applications.

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.
