Its 4 main poles (4 NO contacts) support switching of all phases (and neutral if needed), making it versatile for different wiring schemes. B6‑40‑00 features a relatively low‑consumption coil, silent (hum‑free) operation, and offers a variety of connection types (screw terminals, flat pins, solder pins) depending on variant — making it suitable for panel or DIN‑rail mounting, installation in compact control cabinets, or retrofit in existing systems.

The ABB KC6‑31Z‑05 is a compact 4‑pole mini‑contactor relay (mini contactor) designed for control‑circuit switching and light to moderate loads. It uses a DC‑operated coil (for this “‑05” version), making it suitable for control from DC sources such as PLC outputs or DC logic circuits. The unit is built for applications where space is limited but reliability is required — for example control panels, automation equipment, residential or commercial building control, and industrial control circuits. The coil is “hum‑free / noiseless”, giving quiet operation; the unit uses screw terminals and can be DIN‑rail or panel mounted. Because of its small size and compact 4‑pole configuration, it is also useful for switching multiple lines (e.g. three‑phase plus neutral) or multi‑circuit control in compact switch boxes.

The ABB B7D‑40‑00 is a compact 4‑pole miniature contactor designed for switching AC or DC control circuits and moderate three‑phase or single‑phase loads. It provides a space-saving solution for control panels, automation cabinets, HVAC systems, small machines, lighting circuits, and general-purpose switching tasks. The B7D‑40‑00 uses a DC-operated coil to enable control via DC control circuits while providing AC switching capability for the main circuit. It is designed for durability, stable operation, and multiple switching cycles, making it suitable for both industrial and commercial control environments.

This contactor is suitable for compact control panels, automation cabinets, small motor starters, HVAC systems, and other applications where space is limited and loads are moderate. It supports DIN‑rail or wall mounting and is designed for reliable operation up to 690 V AC.

The ABB B7‑30‑10 is a compact 3‑pole miniature contactor (mini‑contactor) from ABB’s B7/B-series, intended for switching small to medium three‑phase loads such as small motors, resistive or inductive loads, and general three-phase circuits in panel, building, or light‑industrial installations. It features 3 normally‑open main contacts plus one built‑in auxiliary contact for control or signaling, making it suitable for load switching with optional auxiliary control logic. Thanks to its compact size, screw‑terminal connections, and versatile coil‑voltage variants (AC or DC depending on version), B7‑30‑10 is well suited for space‑constrained control panels, small motor starters, HVAC systems, pumps, or general-purpose switching applications where reliability and modest current rating suffice.

The ABB BC6‑30‑10 is a compact 3‑pole miniature contactor designed for switching small to moderate three‑phase AC loads, such as small motors, resistive/inductive loads, and general-purpose circuits. As a mini‑contactor from ABB’s BC6/B6 family, it offers a compact form factor for space‑constrained control panels, automation cabinets, or small motor‑control applications. It features three main normally‑open (NO) contacts for the main circuit and includes one built‑in auxiliary contact (NO) for control or signaling purposes. The coil is typically DC‑operated with low power consumption, making it compatible with PLC outputs or low‑power control circuits. The BC6‑30‑10 is suitable for small motor starts, resistive loads, lighting loads, and other light-to-medium three-phase switching tasks up to its rated current and power.

The ABB UA95‑30‑00 is a 3‑phase, 3‑pole contactor intended primarily for capacitor switching or lighter duty power‑circuit control (rather than heavy motor switching). It offers reliable switching of three-phase circuits, with a compact design suitable for control panels, capacitor banks, or power‑factor correction systems. The design supports a broad control-voltage range (depending on coil variant), giving flexibility for different control‑voltage supplies. The contactor features robust main‑circuit terminals (bar or cable‑clamp type), and is rated for up to 1000 V AC in the main circuit (IEC standard). Its electrical and mechanical durability makes UA95‑30‑00 a solid choice for capacitor switching, reactive-power management, or general three-phase load control in industrial/commercial installations.
