Industrial 46FB Contact Block

The Furnas Electric Co. 46FB Industrial Contact Block is a three normally open (3NO) auxiliary contact module designed for use in industrial control circuits, enabling straightforward expansion of relay logic within machines, control panels, and automation cabinets. It is rated to switch up to 600 VAC and carry 10 A, providing reliable performance for medium-power control tasks such as interlocking, signaling, and sequencing in complex control networks. The coil is specified at 110–120 V AC with 50/60 Hz input, aligning with common control power supplies used in many facilities and simplifying compatibility with standard automation components and field wiring practices. As a 46FB contact block, it consolidates three normally open contacts into a single block, reducing wiring complexity and enabling flexible expansion of control logic in automation setups for compact panel layouts. Model 46FB identifies this unit within Furnas' lineup of industrial contact blocks.
