The ABB S202-K20 (Order Code: 2CDS252001R0487) is a 20A, 2-pole, K-curve Miniature Circuit Breaker (MCB) from the ABB S200 Series (System PRO M). This specialized MCB is designed for industrial and commercial applications where protection of circuits with very high inrush currents, particularly from transformers, solenoid valves, and certain types of lighting (e.g., discharge lamps), is required. The "K" curve features a delayed and higher magnetic trip setting compared to standard curves, providing immunity to short-duration, high-magnitude startup surges while maintaining robust protection against sustained overloads and short circuits.

The ABB SH201-C10 is a 10A, 1-pole, C-curve Miniature Circuit Breaker (MCB) from the ABB System PRO M compact® series. It is a compact, single-module protective device designed for final sub-circuit distribution in single-phase applications within residential, commercial, and light industrial installations. This MCB provides essential protection against overloads and short-circuits for individual electrical lines, cables, and connected equipment. Its "C" tripping characteristic offers a standard magnetic setting, making it the universal choice for protecting general circuits with typical inrush currents, such as lighting circuits, small appliance socket outlets, and control wiring.

The ABB SH202-D32 (catalogue code 2CDS212001R0321) is a 32A, 2-pole, D-curve Miniature Circuit Breaker (MCB) from the ABB System PRO M compact® series. This MCB is engineered to provide reliable overload and high inrush current protection for circuits with significant startup surges. The "D" tripping characteristic features a delayed magnetic response, making it the ideal choice for protecting inductive loads such as transformers, solenoids, welding equipment, and particularly single-phase and certain three-phase motors, where high starting currents (up to 10-14 times the rated current) are common. It prevents nuisance tripping during equipment startup while maintaining robust short-circuit protection.

The ABB SH202-C3 is a three-pole, high-performance miniature circuit breaker (MCB) designed for final distribution in residential, commercial, and light industrial electrical installations. Belonging to ABB's well-regarded System PRO M compact® series, it provides reliable protection against overloads and short-circuits for electrical circuits, equipment, and cables. The “C” curve indicates a medium magnetic tripping characteristic, making it particularly suitable for protecting mixed loads with moderate inrush currents, such as lighting, socket outlets, control circuits, and small motors. This MCB is characterized by its compact design, high breaking capacity, and compliance with international standards.

This device is an ABB Selector Switch Head Kit, complete with indicator light (neon), for 22.5mm push-buttons. It is designed for panel mounting on standard 22.5mm mounting holes and is primarily used for assembling or customizing control devices (like selector switches, key-operated switches, or emergency stop buttons) on industrial control stations and operator panels. The integrated neon indicator provides visual status feedback.
