The ABB KC6-31Z-05 Mini Contact Relay is a compact, 4-pole contactor relay designed for control and switching applications in residential, commercial, and light industrial environments. It is intended for switching control signals and small loads and is especially suited where space is limited and reliable operation is required. The device features a DC-operated coil with low power consumption, screw-type terminals for easy wiring, and robust construction for long operational life. Its noiseless, hum-free coil design and clear switching indication make it ideal for automation panels and control circuits with DC control voltages of 220-240 V.

The ABB OT100FT4N2 is a compact non-fused switch-disconnector designed for safe and reliable manual isolation in low-voltage power distribution systems. It features a 4-pole configuration with a front-operated mechanism, making it suitable for door-mounted installations in control panels and electrical enclosures. The switch provides high switching performance under load conditions and complies with international IEC and UL standards.

The ABB CR-M230AC4 is a modular contact block designed as an accessory for ABB's CR-M series of industrial pushbuttons, selector switches, and pilot devices. It provides additional electrically isolated auxiliary contacts that are mechanically actuated by the main operator (e.g., a pushbutton head).

The ABB CT-MFD.12 is a current transformer (CT) from the ABB MFD series, designed for general-purpose measurement and monitoring of alternating current in low-voltage electrical systems. It is a split-core or "clamp-on" type current transformer, allowing for easy installation on existing busbars or insulated cables without the need to disconnect the circuit.

The ABB E16DU6.3 is a three-phase (3P), thermal-magnetic circuit breaker from ABB's E16 series (also known as the DS260 series or Form 1a), specifically designed for motor circuit protection. It combines the functions of a disconnect switch, a thermal overload relay, and a magnetic short-circuit protector in a single, compact unit.

The ABB A63-30-11 AC220V is a 63A, three-pole contactor from the classic and globally recognized ABB A-series (also known as the AF series or "System Pro M compact®" contactor line). It is a rugged, reliable electromagnetic contactor designed for frequent switching of three-phase AC loads, most commonly electric motors, but also heaters, transformers, and capacitors.

The ABB GDA204 AC-40/0.03 is a four-pole (4P), 40 A, 30 mA (0.03 A) Residual Current Device (RCD) Module, specifically designed for modular mounting on busbar systems in Distribution Boards (DBs) and Consumer Units. It is part of ABB's GDA series of DIN-rail mounted RCDs.

The ABB CP1-30W-10 is a compact, single-phase, DIN-rail mounted AC/DC switching power supply from the ABB CP1 series. It is designed to provide a reliable, regulated 24V DC output for powering control circuits, sensors, actuators, and other low-voltage devices in industrial automation and building control systems.

The ABB A3N630 TMF500/5000 FF 3P is a high-performance, fixed-mounted, three-pole Air Circuit Breaker (ACB) from ABB's renowned Emax series (E框架). It is designed for primary power distribution and protection in large commercial buildings, industrial plants, and critical infrastructure.

The ABB CL2-507R is a 2-pole (1P+N), C-curve, 10 kA breaking capacity, Residual Current Circuit Breaker (RCBO). It belongs to the ABB CL (Circuit breaker Line) series, also commonly known as the "HomeLine" or DS200 series in some markets, designed for residential, commercial, and light industrial final circuit protection.
