Differences Between The New Current-Limiting Fire Protection Device And The Old Model

Compared with older models, the new current-limiting fire protection devices typically differ in the following aspects:

Performance Improvements

• Faster short-circuit protection: Older models generally cut off circuits at millisecond-level speed, while new models can quickly limit short-circuit current at "microsecond-level" speed.

• Higher current-limiting precision: New models employ more advanced sensors and control technology to detect and limit current more precisely. They can respond rapidly the moment the current reaches a dangerous threshold and limit the current within a safe range, reducing damage to circuits and equipment caused by current fluctuations.

• Smarter overload protection: Older models have relatively fixed action times and thresholds for overload protection, while new models can automatically adjust protection parameters based on actual load conditions, adapting to more complex power usage environments. They can also monitor and assess overload duration more precisely, avoiding false trips or delayed actions.

Expanded Functionality

• Added environmental monitoring function: In addition to basic current protection functions, new models integrate smoke detection, combustible gas detection, and other functions. For example, the Jiangguang Electric JGFH-63 can monitor and alarm for excessive levels of combustible gases such as liquefied petroleum gas and natural gas, as well as smoke conditions

• Arc fault detection capability: Some new products feature arc fault detection, which can promptly identify
