Siemens 52PP2MRA Mushroom Head Push Button 1-3/4 Inch

Product Description

The SIEMENS 52PP2MRA is a mushroom head push button operator designed for industrial control panel applications. The extended mushroom-style actuator head measures 1-3/4 inches in diameter, providing a large contact surface for quick, reliable manual actuation. This type of operator is typically mounted to a control enclosure or panel door and paired with contact blocks to complete a control circuit. Electricians and panel builders install this component in motor control, machine guarding, and process control systems where a clearly visible, easy-to-actuate button is required.

The 52PP2MRA is suited for use in industrial and commercial control panel assemblies. Its mushroom head form factor is commonly specified for emergency stop, start, or halt functions where immediate manual intervention is needed. The part belongs to the Siemens PP2 push button series, making it compatible with other components in that operator platform. Installation is typically completed by licensed electricians or panel integrators working on low-voltage control circuits in manufacturing, building automation, or mechanical system control environments.

Key Features

• Mushroom head actuator at 1-3/4 inches diameter for high-visibility manual operation
• PP2 series operator platform for compatibility with corresponding contact blocks and enclosures
• Compact, panel-mount design suited for control enclosure door cutout installation
• Appropriate for motor control, emergency stop, and process halt applications

Compatibility

Designed as an OEM-style operator for industrial control panels using the Siemens PP2 push button series platform. Confirm contact block and enclosure compatibility with the PP2 series before installation.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the control panel before mounting or wiring any push button operator. Ensure the panel cutout dimensions match the operator body before securing the retaining nut. Do not apply excessive torque to the mounting hardware, as this may damage the operator body or enclosure material.
