The ABB E2N1600 R1600 PR121/P-LSI WHR3P NST is a draw-out type, low-voltage Air Circuit Breaker (ACB) from the original Emax (E1/E2) series. It is designed for main distribution in industrial plants, data centers, and large commercial facilities, offering selective protection and the major advantage of easy maintenance and isolation via its draw-out design.

The ABB 1SDAX00057R1 is a DC Power Supply Module specifically designed for the auxiliary control circuits of ABB Emax E1 and E2 series Air Circuit Breakers (ACBs). Its primary function is to convert an external AC supply voltage into a stable, low-voltage DC output to power the critical electronic components of the breaker.

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.
