SEMOD129275-40 v8
One-phase version of the IED with two low-impedance differential protection zones and twelve
CT inputs B20, B21.
• Due to three available binary input modules, the B20 is intended for applications without
need for dynamic Zone Selection such as substations with single busbar with or without
bus-section breaker, one-and-half breaker or double breaker arrangements. Three such
IEDs offer cost effective solutions for such simple substation arrangements with up to
twelve CT inputs.
• The B21 is intended for applications in substations where dynamic Zone Selection or
bigger number of binary inputs and outputs is needed. Such stations for example are
double busbar station with or without transfer bus with up to 12 CT inputs. Note that
