SIEMENS 30 mm Contact Block 1NO
This SIEMENS contact block provides a single normally-open circuit for 30 mm push-button operators. It suits industrial control panels and automation builds that need a momentary action switch rated for standard control voltages. The black housing identifies the block in dense panel layouts.
Screw terminals and NEMA A600 rating
The block uses screw terminals for secure wire termination in vibration-prone environments. A NEMA A600 designation confirms the contact rating of 10A AC at 600V AC/DC and 5A DC at the same voltage. CSA and UL listings verify compliance for North American electrical installations.
Direct mount for Siemens 30 mm operators
The accessory mounts directly onto compatible Siemens 30 mm push-button operators without extra adapters. This integration reduces panel assembly time and ensures mechanical alignment. No additional software or configuration tools are required for installation.

Questions about this item
What current does the 10 A AC / 5 A DC rating at 600 V allow in practice?
The block is rated for 10 amps AC or 5 amps DC at up to 600 volts, matching the A600 NEMA designation for control-circuit duty.
What cut-out and spacing does the 30 mm Siemens push-button series require?
It mounts in a standard 30 mm panel cut-out used by the Siemens 30 mm push-button line; no extra adapters are needed.
How is the screw-terminal block wired, and what mistake should be avoided?
Strip each conductor, insert into the screw terminals and tighten securely; the common error is leaving strands loose, which causes high resistance and overheating.
