Siemens Furnas 46ZB40 4 Pole Contact Block 300V

Siemens Furnas 46ZB40 is a four-pole terminal and contact block designed to mount with compatible Furnas/Siemens relays and contactors, delivering four normally open contacts rated for up to 300 VAC for control circuits. Equipped with screw terminals, this 46ZB40 unit provides straightforward field wiring and acts as a compact interface between a control relay and field devices, enabling isolated dry contacts for signaling, interlocking, or status indication in industrial automation panels. As a 4NO (four normally open) block, it is explicitly listed as a 300 VAC contact block within the Furnas/SIemens product family, making it a direct-fit accessory for compatible control gear where four discrete switch contacts are required.
