Normally Closed Switching for Industrial Control Panels

Four-pole normally closed contactors such as the Lovato BF18T0A57560 are used where contacts must remain closed when the coil is de-energised and open when the coil is energised. This makes the device useful for interlocking, disconnection, load-shedding logic and specialist control circuits within industrial panels.

The 575 V AC 60 Hz coil allows the contactor to be integrated into compatible high-voltage AC control systems. Its four-pole arrangement gives panel designers flexibility when switching multiple conductors or control paths, while the compact BF18 frame supports efficient use of control cabinet space.

Typical Applications

• Industrial control panels requiring 4NC contactor switching.
• Electrical interlocking and control logic circuits.
• Load isolation and disconnection circuits within rated limits.
• Automation panels using 575 V AC 60 Hz control supplies.
• HVAC, pump and machinery control systems.
• OEM machine building and specialist electrical assemblies.
• Panel upgrades where a compact four-pole normally closed contactor is required.
