JouYang Electrical: overload relay manufacturer and overload relays design in China.

Established in 1990, China JouYang Electrical Products Co.,Ltd. is known as a leading overload relay manufacturer and designer of high and low-voltage electric appliance in China. We integrate scientific research, development, production, sale and service in one company. Our custom overload relays products are characterized by their superior dustproof, splash-proof, anticorrosion, fire-resistant, thermo-stability and aging-resistant properties. Having received ISO9001 certification for our manufacturing and sales systems, we have also been issued European 'CE' and Chinese 'CCC' safety authorizations for our products. All of our OEM overload relay products are strictly according to IEC/GS/EMC/LICE/UL/CSA standard and guaranteed by People's insurance Corporation of China (PICC).

0.4 5000 A Current Range
DeviceNet Ready (ODVA Conformance Tested)
LED Indicators
Test/Reset Button
Adjustable Trip Class 5…30
Ambient Temperature Compensation
True RMS Current Sensing (20…250 Hz)
Protection for Single- and Three-Phase motors
Integrated I/O (2 In/1 Out)
Programmable Trip and Warning Settings
Diagnostic Functions (History of Last 5 Trips)
Node Address Switches (series B)
193/592-EC2 also includes:
Integrated I/O (4 In/2 Out)
Low-Level (1.5 A) Ground Fault Protection
PTC Thermistor Monitoring
Two-Speed Motor Protection (series B)
Trip modules with overload relay function ZMR-xx- PKZ2 are inserted in the load side of the motor protector disconnect handle. Similar to the operation of an overload relay, the ZMR uses a set of auxiliary contacts to de-energize a contactor coil circuit and signal an overload condition. A short circuit will trip open the motor protector just like the standard ZM trip module. The ZMR is also supplied with a HAND/AUTO reset feature. It cannot be combined with U/A voltage trips or RE/RS remote control drives.

Z overload relays offer motor protection in the event of single phasing or overload. Their auxiliary contacts disconnect the motor contactor and signal the fault. These relays can also be used for protecting EEx e motors.
The Z relays have been improved and modified for the new xStart system: engineering and inventory management have been facilitated by the reduction in the number of types.
Z thermal overload relays can be mounted directly on DIL M contactors up to 250 A. When required, the relay can also be installed separately.
NR2 series bimetallic strip thermal overload relay is mainly
applicable to a circuit of AC 50Hz / 60Hz, rated working voltage
up to 690V and current from 0.1A to 630A, used to protect a
motor from overload, phase - failure, extra - long starting time and
blocking time.
It can be inserted in a corresponding AC contactor or installed independently.
It can replace JRS1 series thermal over - load relay
Our NR2() Series Bimetallic Strip Thermal Overload Relay comply with International Quality Standards and their quality and durability are fully guranteed.
