Abb a3pb41-600b-10 Mushroom Pushbutton Momentary 1NO Black

Product Description

The ABB a3pb41-600b-10 is a 30 mm mushroom-head pushbutton designed for momentary-action control circuits in industrial and commercial electrical panels. It features a 1NO (normally open) contact configuration and a two-position actuator that returns to its default state when released. The black mushroom actuator provides a large, easy-to-locate target for operators and is commonly used for stop or emergency-stop functions where a conspicuous operator head is required. Licensed electricians and panel builders install this device in control enclosures, machine control panels, and operator interface stations.

This pushbutton is suited for 30 mm panel cutout applications in industrial control systems, motor control centers, and process equipment. The 44 mm cutout size accommodates the mushroom actuator footprint. It is appropriate for use in both light manufacturing and heavy industrial environments where a momentary contact input is needed for PLC or relay-based control circuits. The black color coding supports standard panel layout conventions for stop or normal-function operator devices.

Key Features

• Momentary action returns to default position on release
• 1NO contact configuration for normally open control circuits
• Mushroom actuator head for high-visibility, easy operator engagement
• Black housing for conventional stop or general-function panel identification
• Two-position switching for straightforward on/off control inputs
• 44 mm cutout accommodates the mushroom actuator profile in standard enclosures

Compatibility

Designed as an OEM-style replacement or new-installation component for 30 mm industrial pushbutton operator stations and control panel assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for control circuit wiring. De-energize the control panel and verify absence of voltage before removing or installing the pushbutton. The device mounts through a panel cutout and is secured with the supplied locking nut. Verify contact configuration and circuit type before wiring to avoid unintended energization of downstream loads.
