The ABB PR222MP is an advanced Electronic Trip Unit (ETU) designed for ABB's Tmax XT series Molded Case Circuit Breakers (MCCBs) in the T4 to T7 frame sizes. It represents a significant upgrade from basic thermal-magnetic protection, offering a comprehensive suite of protection, measurement, and communication functions in a single, integrated unit. The "MP" suffix highlights its two core capabilities: M for advanced Measurement and energy metering, and P for Protection configurability via a front keypad.

The ABB YO-1SDA038290R1 is an Electronic Trip Unit (ETU) for ABB's Tmax XT series Molded Case Circuit Breakers (MCCBs). This specific model is the PR222MP-P trip unit. The "-P" suffix typically indicates a specific variant or package, often including additional pre-wired features or a different delivery state (e.g., with a pre-installed communication module or a specific default configuration). Its core functionality is identical to the standard PR222MP, providing advanced protection, measurement, and communication capabilities.

The ABB K6-31Z is a Zener Barrier (Safety Barrier) for Intrinsically Safe (IS) circuits. It is a passive, galvanic isolation device used in hazardous areas (classified zones with explosive atmospheres) to protect sensitive instrumentation and control equipment located in the safe area.

The ABB S2X160 3P 80A is a three-pole, 80 Ampere, Rotary Isolating Switch (Switch-Disconnector) from the ABB System pro M compact® S200 series. It is a compact, modular device designed for safe load switching and isolation in low-voltage distribution and control panels. It provides a visible air gap for isolation and is capable of making and breaking load currents under normal conditions.

The ABB SACE PR1/P is an Electronic Trip Unit (ETU) from the PR1 series, specifically designed for ABB SACE Emax (E1) series Air Circuit Breakers (ACBs). It is a core component that replaces traditional thermal-magnetic releases, providing more precise, adjustable, and feature-rich protection for low-voltage main distribution systems.

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.
