The ABB T6-800 is a Frame Size 800 Ampere, Thermal-Magnetic Molded Case Circuit Breaker (MCCB) from ABB's Tmax XT series (which incorporates the legacy T6 series). It is a high-current, three-pole circuit breaker designed for main power distribution, feeder protection, and safeguarding heavy industrial loads.

The ABB T6-630 is a Frame Size 630 Ampere, Thermal-Magnetic Molded Case Circuit Breaker (MCCB) from ABB's Tmax XT series (which incorporates the legacy T6 series). It is a robust, three-pole circuit breaker engineered for primary feeder protection, main distribution, and safeguarding large industrial loads up to 630A.

The ABB E1N1600 R1600 PR121/P-LI 3P is a fixed-mounted, low-voltage Air Circuit Breaker (ACB) from the original Emax (E1) series. It is designed for main power distribution and protection in commercial and industrial electrical systems up to 690V AC. This specific configuration offers robust protection with a focus on overcurrent and short-circuit faults.

The ABB OS32D12 is a 32 Ampere, Double-Pole (2P) Rotary Isolating Switch (Switch-Disconnector) from the ABB OS Series. It is a manual, load-breaking switching device designed primarily for safe isolation of electrical circuits. Its core function is to provide a visible, reliable "off" position to de-energize equipment for maintenance or repair, while also being capable of making and breaking load currents under normal operating conditions.

The ABB YU-1SDA085619R1 is a Control and Auxiliary Power Supply Module for ABB's Emax series Air Circuit Breakers (ACBs).

The ABB VD4M 1206-25 is a Medium Voltage (12kV), Fixed-mounted Vacuum Circuit Breaker from ABB's renowned VD4 series. It is a spring-operated, indoor vacuum circuit breaker designed for primary switching, protection, and control in medium voltage power distribution networks. It is typically installed in metal-clad or air-insulated switchgear for use in utility substations, industrial plants, and large commercial facilities.

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.
