Designed with special attention to the dimensions, the 3-pole contactors are just 105mm wide, like the equivalently rated moulded case circuit breakers (MCCB), so the starters are more compact and easier to be connected.
The BF160, BF195 and BF230 contactors have an electronically controlled AC/DC coil for greatly reduced consumption and a wide nominal voltage range (e.g. just one coil for 100…250V AC/DC), which ensures operation without uncertainness, even under strongly varying supply voltage conditions.
The low profile front-mounted auxiliary contacts enable quick and easy wiring. Up to 6 contacts can be mounted on the 3-pole contactors, and up to 8 on the 4-pole contactors. In addition, up to 8 contacts can be mounted on the side faces.
A variety of accessories are available to facilitate the assembly of functional, safe panels: power terminal protections, isolating phase barriers, terminal enlargement kit to connect large wires and lugs, and a connection kit for assembling changeover, reversing and star delta starters.
A horizontal mechanical interlock mounts flush between the two contactors without increasing the assembly’s overall dimensions. The interlock is also available in a vertical version.
