Protection Relay
NJB1-Y Single-Phase
Voltage Relay
1. General
NJB1-Y single phase voltage relays (hereinafter the relay for
short) are applied in AC 220V, 110V, 24V, frequency 50Hz
(or 60Hz) and DC 24V control circuits as single phase over-
voltage protection or under-voltage protection and indication
elements, making or breaking circuits as intended operating
values and time.
The product are in compliance with requirements of
standard IEC 60947-5-1
