16A Emergency Stop Switch PA66 IP55

Overall dimensions: 117 mm length × 68.6 mm width. No height specified. Weight not provided. Rated operational current: 16 A continuous; maximum switching capacity: 18 A (resistive, AC-1), 15 A (inductive, AC-3). Nominal system voltage: AC 250 V. Coil supply: 220–240 V AC, 50/60 Hz. Terminal type: 4-pin screw clamp, accommodating 1.5–2.5 mm² conductors. Protection class: IP55 — tested to IEC 60529 for dust resistance and resistance to water projected by nozzle from any angle. Mechanical endurance: 50,000 cycles minimum. Thermal class: T85/55 — designed for continuous operation at ambient temperatures up to 85 °C with ≤55 K temperature rise at terminals. Functions include instantaneous dual-pole disconnection for emergency stop, plus undervoltage hold-off: if supply drops below threshold, the coil de-energises and remains latched open until reset. Optional brake mode engages single-pole cut-off for smoother motor coast-down. Can be cascaded with overload relays to deliver coordinated protection — essential for CE-marked machinery sold in GB and EU markets. Commonly installed on UK-manufactured or imported machine tools (e.g., table saws, planers), portable garden equipment (e.g., chipper-shredders), and light industrial automation panels — functions as a Category 0 safety component per BS EN ISO 13850 and aligns with PUWER 1998 requirements for stop controls.
