NSX100N MCCB 100-125A

Short Description:

JNSX Moulded Case Circuit Breaker

1.Application

UNS series plastic housing circuit breaker. They are characterized by compact size, modularization,high breaking, double break points, zero flashover, and green environmental protection. It issuitable for distribution networks with AC 50Hz, 60Hz, rated working voltage 690V and below, andrated current 12.5A to 1600A. It is used to distribute electric energy and protect lines and powerequipment from overload, short circuit, undervoltage, and other faults. It can also be used forinfrequent switching of lines and infrequent starting of motors under normal conditions.

The JNS series circuit breaker is also equipped with an intelligent controller, which not onlyincreases the selection range of setting current, but also has LCD display, overload setting current,short circuit delay current, short circuit instantaneous current, and tripping time that can beset, as well as short circuit instantaneous three-stage protection and undervoltage protection;

Equipped with RS485 communication interface and MODBUS-RTU protocol; DL645 protocol, userscan choose according to their needs. Remote signaling: breaking/closing, tripping, alarm, and faultstatus indication; Remote control: breaking, closing, resetting: Telemetry: three-phase current andN-phase current, grounding current, trip memory function, and functions such as querying triprecording parameters, further improving the reliability and continuity of power supply. This circuitbreaker also has an isolation function (can be used instead of a load switch).

This series of products comply with GB/T14048.2, GB/T 22710, and IEC 60947-2 standards, andhave passed 3C, CE, and TSE certifications.
