Key Features Emergency Stop Function: Designed to provide a reliable manual emergency stop input in control systems. Actuation: Large 40 mm red mushroom head for easy and quick activation. Release Mechanism: Twist‑to‑release — button stays engaged until released by twist. Contact Configuration: 1 Normally Open (NO) + 1 Normally Closed (NC) auxiliary contacts. Range: Part of ABB’s compact pilot device series — minimal installation footprint. Non‑Illuminated: No built‑in lighting — simple mechanical design. Terminals: Screw‑type terminals for secure wiring connection. Panel Mounting: Fits standard 22 mm panel cut‑out for control devices. Electrical Ratings Rated Operational Voltage: Suitable for a wide range of control voltages up to typical industrial values (e.g., 24 V to 300 V AC/DC). Current Rating: Designed to carry control circuit currents — up to around 10 A at 250 VAC/VDC in typical configurations. Contact Type: Combination of NO and NC contacts suitable for both signaling and circuit interruption in safety circuits. Mechanical & Environmental Operating Temperature: Approximately −25 °C to +70 °C. Storage Temperature: Approximately −40 °C to +85 °C. Mechanical Durability: Designed for high usability with a substantial number of mechanical cycles. Protection Ratings: Front Panel: High degree of protection against dust, water jets and high‑pressure wash (e.g., IP66 / IP67 / IP69K rated front). Terminals: Protection rating at terminals typically IP20.
