The ABB E2N1600 R1600 PR121/P-LSI WHR 3P NST is a draw-out low-voltage air circuit breaker from the original Emax (E1) series. It is engineered for high-current main distribution, providing robust protection and control for industrial, utility, and large commercial electrical systems.

The product ABB YU-1SDA085619R1 is a Control and Auxiliary Power Supply Module, specifically designed for ABB's Emax series (E1 and E2) Air Circuit Breakers (ACBs). It is a versatile, integrated module that provides two core functions

The product ABB E3S 3200R3200 PR121/-LSIG WMP 4P 3p is a four-pole, fixed-mounted Air Circuit Breaker (ACB) from the Emax E3 series, which represents the third and latest generation of ABB's Emax family. This particular model features a unique 4P 3p configuration, providing enhanced protection for systems where neutral conductor monitoring and switching is critical.

The ABB T7H1250A is a Thermal-Magnetic Molded Case Circuit Breaker (MCCB) from ABB's Tmax XT series (previously known as the T7 series). It is a high-current, three-pole circuit breaker designed for main feeder and branch circuit protection in industrial, commercial, and utility low-voltage distribution systems. This is a fixed-thermal magnetic version, meaning its protection characteristics are determined by fixed, factory-set internal mechanisms.

The ABB T5-630A is a Thermal-Magnetic Molded Case Circuit Breaker (MCCB) from ABB's Tmax XT series (incorporating the legacy T5 series). It is a three-pole, fixed-trip circuit breaker designed for reliable feeder and branch protection in a wide range of low-voltage applications, including industrial panels, commercial distribution boards, and machine main switches.

The ABB T6-800A is a Thermal-Magnetic Molded Case Circuit Breaker (MCCB) from ABB's Tmax XT series (incorporating the legacy T6 series). It is a robust, three-pole circuit breaker designed for main distribution and heavy-duty branch circuit protection in industrial plants, large commercial buildings, and infrastructure applications.

The product ABB YCE 1.2..E6.2 refers to a specific configuration within the ABB CM-ENS (Energy and Power Management) series. It is a compact multifunction digital power meter and relay. This device is designed for installation in low-voltage switchboards to monitor, measure, and control electrical parameters of a single three-phase circuit.

The product code ABB REF543KM129 A A A A refers to a specific, fully configured unit of the ABB REF 54x series, which is a bay controller and protection relay designed for medium voltage switchgear applications. The REF 543 is a versatile, modular numerical relay used for the protection, control, monitoring, and measurement of feeders, motors, transformers, and generators in utility and industrial power distribution networks (typically 6-36 kV).

The product ABB MT25H1 is a Motor Protective Circuit Breaker (MPCB), also commonly known as a manual motor starter or combination starter. It is a fully integrated device designed specifically for the control and protection of small three-phase motors.

ABB RHEF-P is a specific communication and human-machine interface (HMI) module designation within the ABB Relion® series of protection relays. It is not a standalone relay, but a key component or feature package that constitutes part of high-end ABB digital protection relays such as the REx5xx, REF5xx, and RET6xx series. The "P" typically stands for "Panel-mounted" or "Front-mounted", indicating its design for installation on a control panel or switchgear door.
