Series Overview
Series Overview
Class I (B) 5SD74 T1
- Passes 10/350μs shock test current
- Used to protect low - voltage systems from overvoltage damage including lightning strikes
- Plug - in design for easy replacement
- Maximum continuous working voltage Uc: 350VAC, 50/60Hz
- Voltage protection level Up: ≤1.7KV
- Contacts can perform remote fault indication
- With a fault indication window on the body
- Can perform mechanical coding for all plugs
- With anti - slip terminals
- Active energy control ensures energy coordination with Class I SPD
- Follow - current capability up to 50kA
- TN - C, TN - S, TT systems
- All models have remote indication contacts
- Common installation location: main distribution cabinet
Class II (C) 5SD74 T2
- Passes 8/20μs discharge current test
- Plug - in design for easy replacement
- With a fault indication window on the body
- Used as a surge protector for the DC side of the inverter
- Class II surge protectors are mainly used for lower - level protection of Class I surge protection in the main distribution cabinet or used in distribution cabinets. They play a protective role against transient overvoltages in low - voltage systems. The product provides more reliable safety protection against overloads. At the same time, the surge protector product can be equipped with a remote signal switch to display the product fault status.
Surge and Surge Protection for Photovoltaic Systems
- Profit margin is crucial for the development of photovoltaic systems. The geographical location and climate conditions of the system installation point determine the scale of system investment, as well as the return rate and profit margin. Therefore, surge and surge protection become particularly important. Transient overvoltages caused by lightning and surges will directly damage the photovoltaic system. For example, damage to the inverter due to lightning strike directly means a loss of about 10% of the total investment, and the related subsequent maintenance costs are about 20% of the total investment.
- Siemens 5SD74 series surge protectors can provide safe and reliable surge and surge overvoltage protection on both the DC side and AC side of the inverter.
Class III (D) 5SD74 T3
- Plug - in design for easy replacement
- Used to protect terminal equipment in single - phase or three - phase power grids
- Rated voltage Un = 24V, Un = 60V, Un = 120V or Un = 230V
- Suitable for AC and DC systems
- Contacts can perform remote fault indication
- With a fault indication window on the body
- Can perform mechanical coding for all plugs
