Size of breaker for lift
The size of a breaker for a lift (elevator) depends on several factors, including:
- Lift capacity: The weight of the lift, including passengers, cargo, and equipment.
- Lift speed: The speed at which the lift moves between floors.
- Number of stops: The number of floors the lift serves.
- Type of lift: Traction, hydraulic, or pneumatic.
- Local electrical codes and regulations: Compliance with local electrical codes and regulations, such as those related to fault current ratings and short-circuit currents.
Here are some general guidelines for selecting a breaker for a lift:
- Traction lifts:
- For small lifts (up to 1,000 kg capacity), a 63A or 80A breaker is suitable.
- For medium lifts (1,000 kg to 2,000 kg capacity), a 125A or 160A breaker is suitable.
- For large lifts (above 2,000 kg capacity), a 250A or 315A breaker is suitable.
- Hydraulic lifts:
- For small lifts (up to 1,000 kg capacity), a 32A or 40A breaker is suitable.
- For medium lifts (1,000 kg to 2,000 kg capacity), a 63A or 80A breaker is suitable.
- For large lifts (above 2,000 kg capacity), a 125A or 160A breaker is suitable.
- Pneumatic lifts:
- For small lifts (up to 1,000 kg capacity), a 16A or 20A breaker is suitable.
- For medium lifts (1,000 kg to 2,000 kg capacity), a 32A or 40A breaker is suitable.
- For large lifts (above 2,000 kg capacity), a 63A or 80A breaker is suitable.
Keep in mind that these are general guidelines, and the actual breaker size required may vary depending on the specific lift design, electrical system, and local regulations. It is recommended to consult with a qualified electrical engineer or a lift manufacturer to determine the appropriate breaker size for your specific lift installation.
