60 amp 3 phase fused disconnect, designed for AC 50Hz operation, rated voltage up to AC690V, combine the functions of a fuse and a switch, disconnecting power in the event of an overload or short circuit. When the current exceeds the safety limit, the internal fuse element melts, immediately disconnecting the circuit, protecting wiring, sensitive electronic equipment, and motors from damage or fire. This switch complies with GB/T14048.3 and IEC60947-3 standards.

Environmental Condition
1. Ambient air temperature: not higher than +40°C, not lower than -5°C.
2. Installation altitude: not more than 2000m.
3. Ambient pollution level: Level 3.
4. Humidity: At a maximum temperature of +40°C, the relative humidity should not exceed 50%. Higher relative humidity is permitted at lower
temperatures, for example, up to 90% at 20°C. Special measures should be taken to prevent occasional condensation caused by
temperature fluctuations.
5. The switch should be installed in an area free from significant shaking, impact, vibration, rain, or snow. The installation location should also be free
from explosive media and gases and dust that could corrode metal or damage insulation.
Structural Features
1. An accelerator mechanism with instantaneous release of spring-loaded energy enables rapid connection and disconnection, independent of handle speed, improving arc extinguishing capability.
2. The housing, constructed of unsaturated polyester fiberglass-reinforced molding compound (DMC), offers excellent smoldering resistance, dielectric properties, and operational safety.
3. The parallel multi-break contacts are self-cleaning and provide reliable overcurrent and short-circuit protection.
4. Ensures circuit connection and disconnection under load.
5. Safe, convenient, and quick fuse replacement.
Installation Notes
The switch contact parameters are set by the manufacturer and should not be adjusted during use.
When connecting the busbar to the product, ensure that the busbar hole spacing is consistent with the product wiring holes to avoid damage to the
product due to external forces.
Ordering Instructions
1.We need get the product name, model, rated current, number of poles, and quantity from customers.
