The AC400V 160A Emergency Fuse Switch Industrial serves as a critical safety component in industrial electrical systems, providing reliable isolation and emergency shutdown capabilities for high-power circuits. This robust switching device combines manual operation with integrated fuse protection, offering a dual-layer safety mechanism for industrial environments operating at 400V AC with current loads up to 160A. Compliant with EN 60947-3 standards, the switch features a visible break contact design that provides unambiguous confirmation of circuit isolation, essential for maintenance safety and fault troubleshooting in industrial facilities. Its rugged construction ensures reliable performance in harsh industrial environments with high levels of vibration, dust, and temperature fluctuations.
Engineered to handle industrial fault conditions, the switch achieves a breaking capacity of 36kA at 400V, ensuring safe interruption of high fault currents without sustaining damage. The integrated fuse holders accept standard NH-type fuses (NH00 to NH2 sizes), providing precise overcurrent protection tailored to specific circuit requirements. This combination delivers both reliable emergency switching and calibrated overload protection.
The switch incorporates multiple safety features including a positive break mechanism that ensures complete circuit disconnection even under spring tension loss. A visible blade contact design provides clear visual confirmation of the open position, with a mechanical interlock preventing accidental closure during maintenance. The enclosure features IP20 protection against solid objects and includes a lockable handle (padlockable in both on and off positions) to prevent unauthorized operation.
Constructed with a powder-coated steel enclosure and tin-plated copper contacts, the switch offers exceptional durability with a mechanical service life of 10,000 operations and electrical service life of 2,000 operations at full load. It operates reliably in ambient temperatures ranging from -5℃ to 40℃ and can withstand vibration up to 10Hz with 0.15mm amplitude, making it suitable for heavy industrial environments.
This industrial emergency switch is essential for various heavy-duty applications:
Manufacturing facilities power distribution systems
Industrial machinery and production lines
Chemical processing plants and refineries
Water and wastewater treatment facilities
Mining operations electrical infrastructure
Steel mills and metal processing plants
Large-scale HVAC and refrigeration systems
Data center backup power distribution
The visible break provides unambiguous confirmation that the circuit is safely isolated during maintenance or emergency situations. According to EN 60947-3 standards, this design feature ensures that maintenance personnel can visually verify the open status of the switch without relying solely on indicators. The exposed blade contacts create a physical air gap of ≥12mm that prevents accidental reconnection and provides clear proof of isolation.
Fuse selection should be based on the maximum continuous current of the protected circuit, with a recommended rating of 125-150% of the normal operating current. For motor circuits, consider the starting current surge (typically 6-8x rated current) and select time-delay fuses that allow temporary overloads during startup. Consult the manufacturer's guidelines for specific applications, and ensure the fuse breaking capacity exceeds the maximum available fault current at the installation point.
Yes, when properly integrated into an emergency stop system, the switch provides a reliable means of disconnecting power to hazardous equipment. It should be installed in conjunction with emergency stop pushbuttons that activate the switch via auxiliary contacts. For safety integrity level (SIL) applications, the switch meets SIL 2 requirements when used in a properly designed safety circuit, providing a high level of fault tolerance and reliability.
