Frequently Asked Questions
Q: What type of DIN rail does this surge protective device (SPD) fit?
A: This SPD is designed for standard 2P DIN rail mounting, compatible with the widely used 35mm (TS 35) DIN rail found in most residential and commercial electrical enclosures and distribution boards.
Q: What does the visual window indicator show?
A: The built-in traffic-light style visual window displays the operational status of the device at a glance. It allows you to quickly determine whether the SPD is functioning normally or needs attention, without removing it from the rail.
Q: What is the maximum discharge current this SPD can handle?
A: This DIN rail surge protector supports a maximum discharge current (Imax) of 40kA and a nominal discharge current (In) of 20kA, with a voltage protection level (Up) of 3.5kV — providing strong transient overvoltage suppression for connected equipment.
Q: Is this surge protector suitable for outdoor or industrial use?
A: This SPD is designed for low-voltage applications (below 50Vac or 75Vdc) and is best suited for use inside electrical enclosures, distribution panels, or control cabinets in residential, commercial, or light industrial settings. Its PC flame-retardant housing adds an extra layer of safety in enclosed panel environments.
