The ABB MS450-32 is a Complete Motor Starter Combination from ABB's MS (Motor Starter) Series. It is an integrated, compact assembly that combines a Contactor, a Thermal Overload Relay, and a Short-Circuit Protective Device (typically a fuse or a circuit breaker base) into a single, pre-assembled unit. This specific model is designed for the direct control and protection of a three-phase motor with a full load current of approximately 32 Amperes.

The ABB SACE F2H 2500A is a Frame Size 2500 Ampere, High Breaking Capacity, Low-Voltage Air Circuit Breaker (ACB) from the ABB SACE Form 2 (F2) series. This is a legacy series, known for its robust construction and designed for primary power distribution and protection in large industrial plants, commercial complexes, and utility substations.

The ABB RS 641 014-AA is an Electronic Room Thermostat / Temperature Controller designed for integration into ABB i-bus® KNX building automation systems. It is part of the Busch-Jaeger RS 640 series of sensors and actuators. Its primary function is to measure ambient room temperature and provide intelligent control signals to regulate heating, cooling, or ventilation systems based on user settings and predefined logic.

The ABB 1SDA038661R1 is a low‑voltage air circuit breaker (ACB) from ABB’s S5N series, designed for industrial and commercial electrical distribution systems. This breaker is configured as a three‑pole (3P) device rated for a 630 A continuous current with a PR211/L‑LI electronic protection trip unit. It offers adjustable protection against overloads and short‑circuit faults.

The ABB S7S1250 PR211/P‑LI FF 4P is a low‑voltage molded‑case circuit breaker (MCCB) designed for industrial and commercial electrical power distribution. It is built on ABB’s Isomax S7 frame, engineered to provide reliable protection and switching for three‑phase power systems with neutral (4‑pole), and a continuous rated current of 1250 A.

The ABB PR211/P-LI is a versatile, compact, and user-friendly overcurrent protection relay designed for low-voltage power systems. It belongs to the "Micrologic Core" family of electronic trip units for ABB's Emax 2 air circuit breakers (ACBs) and Tmax XT molded case circuit breakers (MCCBs).

The ABB BK15291 is a 3-pole, 1 A miniature circuit breaker from the BK/BKM Series. It is designed for domestic and commercial installations to provide reliable protection against overloads and short circuits.

The ABB MS495‑40 is a manual motor starter / motor protective circuit breaker designed for direct manual control and protection of electric motors in industrial and commercial applications. It provides manual switching ON/OFF of motors as well as overload, short‑circuit, and phase failure protection without the need for a separate fuse. The device incorporates a trip‑free mechanism and a clear rotary handle with position indication for ON / OFF / TRIP status, and the handle is lockable to prevent unauthorized operation. The MS495 series is suitable for use with three‑phase and single‑phase motors and is typically mounted on a standard DIN rail

The ABB T6N800 DC TMA800‑8000 4P FF is a low‑voltage molded case circuit breaker (MCCB) from ABB’s Tmax T6N series designed for electrical protection and switching in industrial and commercial power systems. It is rated for 800 A continuous current and features a thermal‑magnetic (TMA) trip unit providing combined overload and short‑circuit protection in a compact fixed frame.
