Emergency Stop Push Button 30mm

The SIEMENS 52PP2W2AP is a maintained-action emergency stop push button with a 30mm mounting diameter and a 45mm red push-pull knob. It features a plastic head with a chrome-plated metal bezel and provides one normally open and one normally closed contact. The unit carries NEMA ratings 1, 3, 3R, 4, 4X, 12, 13 and IP ratings IP20 and IP66, making it suitable for industrial safety circuits requiring positive disconnection.

Safety Switch for Industrial Panels

This switch suits control panels and machinery where a clearly identified emergency stop function is required and screw-terminal wiring is preferred. It is not intended for applications needing illuminated operators, momentary action, or a different contact configuration such as 2NO or 2NC. Buyers who need a smaller mounting footprint, a key-release mechanism, or a higher contact count should look at alternative safety switch models.

Simple Screw-Terminal Installation

Installation uses standard screw terminals that accept ring or fork lugs for secure connections. The 30mm cut-out fits common panel layouts and the chrome bezel threads into place without special tools. Common issues include over-tightening the mounting nut which can crack the plastic head, and failing to torque the screw terminals to the manufacturer specification, leading to loose contacts under vibration.

Questions about this item

What panel cut-out size do I need to mount the 30 mm operator?

The push button requires a standard 30 mm panel cut-out for the operator head.

Will the screw terminals accept the same wire gauge as my existing A600/P600 contact blocks?

Yes, the screw terminals are designed for the A600/P600 NEMA contact rating used on this device.

How can I verify the IP66 seal is intact after installation?

Inspect the chrome-plated metal bezel and plastic head alignment; a proper fit with no gaps confirms the IP66 rating.
