SACE PR121/P E3H08斷路器應用案例

一、關於SACE PR121/P E3H08斷路器的基本信息

（一）所屬係列及框架斷路器特性 PR121/P E3H08

這是ABB的框架斷路器，Emax係列框架斷路器具有一些共同的特性。例如全係列斷路器具有同高度及同深度的特性，抽出式適合安裝在深度500mm的配電盤中，寬度324mm（額定電流高達2000A）抽出式斷路器可安裝在隔間寬400mm的配電盤中，這些尺寸設計精巧，可替換早期的空氣斷路器。其操作機構屬於儲能型，可用預先儲能的彈簧操作，彈簧儲能可手動操作前面的手柄或利用齒輪式電動機電動操作，分閘彈簧在合閘操作時自動儲能。

（二）保護單元相關 PR121/P E3H08

常配的保護單元型號有PR111、PR112、PR121、PR122、PR123等，SACE PR121/P作為保護單元，為斷路器提供保護功能相關的支持。

二、產品可能具備的性能特點 PR121/P E3H08

（一）安·性方面 PR121/P E3H08

防護等級與操作安·性 PR121/P E3H08

有多種方式確保安·性，如櫃門關閉時可搖出斷路器，對外防護等級達IP54，還帶有各種不同安·鎖和雙重絕緣。例如abb空氣斷路器Emax E3H1600 SACE PR121/P - LSI撥碼式三段三極就具備這樣的安·性保障，E3H08可能也有類似的安·設計思路。

極柱結構安·性 PR121/P E3H08

創新性的極柱結構設計，既能確保相線間以及相線與中性線之間完全絕緣，而且可以查看滅弧室和主觸頭的狀態，這對於E3H08斷路器在電路中的安·穩定運行有重要意義。

（二）功能與性能參數方面 PR121/P E3H08

額定電流與分斷能力 PR121/P E3H08

雖然沒有直接查詢到E3H08的額定電流與分斷能力準確數值，但Emax係列的額定電流範圍是400A至6300A，分斷能力由42kA至150kA（380/415VAC），E3H08的相關參數可能在這個範圍內，並且不同的應用場景可能會根據需求進行選型配置。

智能功能 PR121/P E3H08

智能保護脫扣器配有先進的電子元器件，可以度身定制不同的控制和保護方案。還具有新的保護功能和報警功能，並且可能可以通過藍牙技術連接到外部設備（如手提電腦/筆記本電腦），不過這需要根據具體產品配置確定，E3H08可能具備這樣的智能化潛力。

1. Basic information about SACE PR121/P E3H08 circuit breaker

(1) Series and frame circuit breaker characteristics

This is ABB's frame circuit breaker. The Emax series frame circuit breakers have some common characteristics. For example, the full series of circuit breakers have the same height and depth characteristics. The withdrawable type is suitable for installation in a switchboard with a depth of 500mm. The withdrawable circuit breaker with a width of 324mm (rated current up to 2000A) can be installed in a switchboard with a compartment width of 400mm. These dimensions Compact design to replace earlier air circuit breakers. Its operating mechanism is an energy storage type and can be operated by a pre-stored spring. The spring energy storage can be manually operated by the front handle or electrically operated by a gear motor. The opening spring automatically stores energy during the closing operation.

(2) Protection unit related

Commonly equipped protection unit models include PR111, PR112, PR121, PR122, PR123, etc. SACE PR121/P, as a protection unit, provides protection function-related support for circuit breakers.

2. Possible performance characteristics of the product

(1) Safety aspects

Protection level and operational safety

There are many ways to ensure safety, such as the circuit breaker that can be rolled out when the cabinet door is closed, the external protection level reaches IP54, and it also comes with various safety locks and double insulation. For example, abb air circuit breaker Emax E3H1600 SACE PR121/P - LSI dial-type three-stage three-pole has such safety guarantee, and E3H08 may have similar safety design ideas.

pole structural safety

The innovative pole structure design not only ensures complete insulation between phase lines and between phase lines and neutral lines, but also allows you to check the status of the arc extinguishing chamber and main contacts, which is important for the safety and stability of the E3H08 circuit breaker in the circuit. Operation is of great significance.

(2) Function and performance parameters

Rated current and breaking capacity

Although the exact rated current and breaking capacity of E3H08 are not directly available, the rated current range of the Emax series is 400A to 6300A, and the breaking capacity is from 42kA to 150kA (380/415VAC). The relevant parameters of E3H08 may be within this range, and Different application scenarios may require selection and configuration based on requirements.

Smart functions

The intelligent protection tripper is equipped with advanced electronic components and can tailor different control and protection schemes. It also has new protection functions and alarm functions, and may be able to connect to external devices (such as laptops/laptops) via Bluetooth technology, but this needs to be determined based on the specific product configuration. E3H08 may have such intelligence potential.
