The ABB S203M-C20 is a three-pole miniature circuit breaker (MCB) from the enhanced-performance S200M series (Moulded Case), part of the System Pro M compact S200 line. It represents a robust and reliable solution for protecting three-phase electrical circuits. This device features a rated current of 20 Amperes per pole and the widely used "C" type tripping characteristic. The defining feature of the S200M series is its superior 10 kA breaking capacity, providing a higher safety margin in installations with potentially higher fault currents compared to the standard 6 kA S200 series.

The ABB MS116-10 is a compact, space-saving miniature circuit breaker (MCB) from the MSxxx series within the broader System M (M200 S-series) family. It features a unique single-pole plus neutral (1P+N) configuration.

The ABB NS44E-25 is a 25-ampere, 4-pole miniature circuit breaker (MCB) from the System E (S200 S-series) product line.This device is a compact MCB designed to provide simultaneous overload and short-circuit protection for all four conductors of a three-phase circuit (three phases and the neutral). It acts as an automatic switch that trips (disconnects) all poles when a fault is detected on any single pole, ensuring complete isolation of the load.

The ABB MJS2-60B is a high-quality rotary isolator switch, also commonly known as a disconnector or load break switch, from ABB's MJ/MJS series of manual control and switching devices. It serves as a main switch or functional isolator in electrical distribution boards and industrial enclosures.

The ABB MT-105B (5 kΩ) is a precision wire-wound measuring transformer designed for current measurement and signal conditioning in electrical protection and control systems. It is part of ABB's extensive range of instrument transformers for relay and meter applications.

The ABB S202M-C8 is a 2-pole miniature circuit breaker (MCB) from the premium S200M series (also known as "S200 Moulded Case" or "System Pro M compact S200" line with higher performance). It represents an upgraded version within the iconic S200 family. This specific model features a rated current of 8 Amperes and the widely-used "C" type tripping characteristic. The key distinction of the S200M series is its superior 10 kA breaking capacity, making it suitable for installations where higher fault current levels are present or anticipated.

The ABB S202-C40 is a highly versatile and widely used 2-pole miniature circuit breaker (MCB) from the industry-standard S200 series. This device is a compact, two-module MCB with a rated current of 40 Amperes and a "C" type tripping characteristic. Its primary function is to provide reliable and coordinated protection against overloads and short-circuits for a complete electrical circuit, disconnecting both live conductors simultaneously.

The ABB MS116-2.5 is a miniature circuit breaker (MCB) from the compact MSxxx series within the broader System M (M200 S-series). It is a highly space-saving device designed for final circuit protection.

The ABB MS2X-10.0 is a 10 kA rated miniature circuit breaker (MCB) from the MSxxx series within the broader System M (M200 S-series) product family. This device is a highly compact, single-pole MCB with a rated current of 10.0 Amperes. Its primary function is to provide reliable overload and short-circuit protection for electrical circuits in residential, commercial, and light industrial applications. It operates by automatically disconnecting the circuit when a fault is detected, thereby protecting the wiring and connected equipment from damage and preventing fire hazards.

The ABB DDA202 AC-25/0.03 is a high-precision, two-pole residual current circuit breaker (RCCB), also commonly known as a Residual Current Device (RCD) or Ground Fault Circuit Interrupter (GFCI).
