Dayton 35V483 22 mm Red Contact Block

The Dayton 35V483 is a 22 mm industrial contact block designed for operator interfaces in control panels. It suits maintenance engineers and panel builders who need a momentary-action switch element with a red actuator. The block carries CSA and UL Listed markings and complies with NEMA A600/Q600 contact ratings. It is not intended for applications that require a normally open contact form or a different actuator colour.

Contact Form 1NC Rated 10A at 600V AC/DC

The single normally closed contact interrupts circuits up to 10 A at 600 V AC or DC, making this rating the decisive specification for circuit compatibility. The block is listed for use with the 32W266 through 32W279 operator series, ensuring mechanical and electrical match. Installers must verify that the control circuit voltage and current stay within the 600 V and 10 A limits. Systems needing a normally open contact or a higher current rating cannot use this block.

Passive Component No Active Cooling Required

As a passive electromechanical device the contact block generates no measurable heat and produces no audible noise during normal switching operations. It draws no control power of its own, so it adds no load to the panel power supply. The only thermal consideration is the ambient temperature inside the enclosure, which must remain within the limits of the wider assembly. No fan, heatsink or ventilation allowance is needed for the block itself.

Questions about this item

What does the 10 A / 600 V rating mean when the block is wired into a control panel?

It means the contacts can continuously carry 10 amperes at up to 600 volts AC or DC, matching the A600/Q600 NEMA designation for pilot-duty circuits.

How does the 22 mm mounting dimension determine which operators this block fits?

The 22 mm size matches standard industrial push-button and selector operators, so it mounts directly on any 22 mm cut-out without adapters.

Which specific operator models are confirmed to accept this 35V483 contact block?

The block is listed for use with operator series 32W266 through 32W279, covering the momentary action devices in that range.
