LOVATO Electric updates its existing range of contactors with a new construction size. The new contactors are rated 265A, 330A e 400A AC-3 (400V) for motor control applications, 450A, 500A e 600A in AC-1 category. They are available in both 3- and 4-pole versions.
The new size, to better adapt to market needs, is the most compact currently on the market; the 3-pole contactors are just 140mm wide, like the equivalently rated moulded case circuit breakers (MCCB), allowing the quick assembly of compact starters.
Coil power terminals
Both coils and power contacts are also available as spare parts and are easy to replace when necessary
The new contactors have an electronically controlled AC/DC coil for greatly reduced consumption and a wide nominal voltage range (e.g., just one coil for 100-250 V AC/DC), which ensures operation without uncertainty, even under strongly varying supply voltage conditions.
The coil power terminals are 4:2, which can be wired on the top side of the contactor and 2 on the bottom side, for a more comfortable connection. Both coils and power contacts are also available as spare parts and are easy to replace when necessary.
Assembly of functional and safe panels
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 and safe panels: power terminal protections, isolating phase barriers, a terminal enlargement kit to connect large wires and lugs, and a connection kit for assembling changeover, reversing, and star delta starters.
Horizontal mechanical interlock
Horizontal mechanical interlock mounts flush between the two contactors without increasing the overall dimensions
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.
Convenient fixing to the panel is achieved thanks to the easy access of the fixing holes and an accessory for tightening the terminal screws with just one tool.
Fire behavior requirements
A front-mounted mechanical indicator shows whether the contactor is open or closed.
The BF265, BF330, and BF400 contactors are compliant with stringent railway regulations for operation under shock and vibration (IEC 61373), and the plastics used in their construction are compliant with the fire behavior requirements of EN 45545. They are also cULus certified.
