NJBK9 Motor protection relay
1. General
NJBK9 series motor protection relay (hereinafter
referred to as “Pro-tecter”) is used for overload protection,
locked rotor protection, phase failure protection, three-phase
unbalance protection, grounding protection and PTC
temperature protection for AC electromotors of a frequency
of 50Hz with a rated insulation voltage of up to 690V and a
rated operating current of 1A-200A during long-term and
discontinuous operation.
This protector is provided with RS485 interface and 4-20mA
current loop transmitter interface for network communication
and performs remote monitor & control on the motor and
fault query through opper computer.
This protecter is usually used to combine with AC contactor.
Standards: IEC 60947-4-1

3. Operation conditions
3.1 Altitude: should not exceed 2000m;
3.2 Ambient tempeature: -5℃~+40℃, and the average
temperature in 24h should not exceed +35℃;
3.3 Atmospheric conditions: The relative air humidity should not
exceed 50% at the maximum temperature of +40℃. The
relative humidity may be higher at lower temperatures, for
example, the air humidity can be up to 90% at +20℃. Special
measures should be taken if condensation occurs on the product
occasionally due to temperature variation;
3.4 Pollution degree: 3;
3.5 The inclination between the mounting plane and the vertical
plane should not exceed ±5°;
3.6 In non-explosive media that do not contain a sufficient
amount of gas or conductive dust to cause metal corrosion or
insulation failure;
3.7 In places with rain and snow protection equipment and not
full of vapor;
3.8 In places where there is no significant shake, impact or
vibration;
3.9 Mounting category: Ⅲ;
3.10 Degree of protection of enclosure: IP20.
