Power supply protection device SP-230

Application:

The protection device SP-220 is designed to protect equipment connected to to 220V AC power supply lines .

SPF-220 is Class III single-phase protection device meeting the requirements of GOST R 51992-2002 (IEC 61643-1-98), GOST R 50030.1-2000, and GOST R 50571.19-2000 by specifications and performance. SPF-220/8 is used in networks with TN-S grounding system and to be installed within 1 a(b) to 2 lightning protection zones (according to IEC 1312-1).

The alarm signal about a dysfunction of SP-220 is passed into the external signalling circuit.

It may be taken from contacts #4, 5 (NC).

  • The degree of climate protection according to GOST 14254 is IP20.
  • The device is available in a plastic case with mounting on a 35mm DIN rail.

Сonnection scheme:


SP-220 MUST BE GROUNDED and installed in the immediate proximity to the protected equipment.

WARNING: for connection of SP-220, ensure that the phase wire on the distribution board has Class gG fuse or current release device as shown in the diagram.

Contacts 4, 5 (NC) are intended to read the information about the device failure due to lightning or other surge overvoltage impacts.
