Key Features Operator Type: Momentary action pushbutton — returns to its normal position after being pressed. Actuator: Extended black actuator for easy manual operation. Illumination: Non‑illuminated. Bezel Material: Chrome metal bezel for durability and aesthetics. Modular Design: Accepts modular contact blocks behind the operator to define the electrical switching function. Series: Part of ABB’s modular pilot‑device range for flexible panel design. Electrical Ratings MP3‑30B itself is operator only; electrical switching ratings depend on the contact blocks installed. Typical contact blocks support control voltages and currents suitable for relays, PLCs, contactors, or other low‑power control circuits. Mechanical & Environmental Panel Mount Hole: Standard 22 mm diameter. Front Protection: IP66 when correctly installed — resistant to dust and water. Operating Temperature Range: –25 °C to +70 °C. Durability: Rated for approximately 2 million mechanical operations. Physical Characteristics Body Size: 22 mm diameter. Weight: ~25 g. Bezel Finish: Chrome metal. Typical Applications Manual start/stop or input pushbutton in control panels. Machine operator interfaces requiring momentary push action. PLC and relay inputs for triggering logic operations. Industrial automation systems using modular pilot devices.
