Frequently Asked Questions
Q: What is the primary function of this DC Isolator Switch?
This switch is specifically designed for solar photovoltaic (PV) power systems to safely isolate DC voltage circuits of up to 1200VDC and 32A, allowing for safe system maintenance and emergency shutoffs.
Q: Which safety standards does this switch comply with?
It complies fully with international standards IEC/EN 60947-3 and AS 60947-3, ensuring reliable electrical and mechanical performance for low-voltage switchgear.
Q: What is the benefit of the 4-pole (4P) design?
A 4P configuration allows for simultaneous switching of four poles. This is highly beneficial for safety in multi-string PV applications or for bridging poles to handle high DC voltage loads effectively.
Q: Can this isolator operate in extreme weather conditions?
Yes, the switch has a wide operating ambient temperature range of -40℃ to +85℃, making it suitable for standard outdoor installation boxes in hot, cold, or high-altitude climates.
Q: What does the IP20 waterproof degree indicate?
An IP20 rating means the device is protected against solid foreign objects (such as fingers) but does not have water ingress protection. It is recommended to be housed inside a distribution board or an external enclosure with a higher IP rating if used outdoors.
Q: What is the insulation limit of this isolator switch?
This unit features an insulated voltage rating of DC 1500V, ensuring safe isolation and preventing electric leakage between the internal circuits and the outer structure.
