SACE PR121/P E3H08断路器应用案例

一、关于SACE PR121/P E3H08断路器的基本信息

（一）所属系列及框架断路器特性 PR121/P E3H08

这是ABB的框架断路器，Emax系列框架断路器具有一些共同的特性。例如全系列断路器具有同高度及同深度的特性，抽出式适合安装在深度500mm的配电盘中，宽度324mm（额定电流高达2000A）抽出式断路器可安装在隔间宽400mm的配电盘中，这些尺寸设计精巧，可替换早期的空气断路器。其操作机构属于储能型，可用预先储能的弹簧操作，弹簧储能可手动操作前面的手柄或利用齿轮式电动机电动操作，分闸弹簧在合闸操作时自动储能。

（二）保护单元相关 PR121/P E3H08

常配的保护单元型号有PR111、PR112、PR121、PR122、PR123等，SACE PR121/P作为保护单元，为断路器提供保护功能相关的支持。

二、产品可能具备的性能特点 PR121/P E3H08

（一）安·性方面 PR121/P E3H08

防护等级与操作安·性 PR121/P E3H08

有多种方式确保安·性，如柜门关闭时可摇出断路器，对外防护等级达IP54，还带有各种不同安·锁和双重绝缘。例如abb空气断路器Emax E3H1600 SACE PR121/P - LSI拨码式三段三极就具备这样的安·性保障，E3H08可能也有类似的安·设计思路。

极柱结构安·性 PR121/P E3H08

创新性的极柱结构设计，既能确保相线间以及相线与中性线之间完全绝缘，而且可以查看灭弧室和主触头的状态，这对于E3H08断路器在电路中的安·稳定运行有重要意义。

（二）功能与性能参数方面 PR121/P E3H08

额定电流与分断能力 PR121/P E3H08

虽然没有直接查询到E3H08的额定电流与分断能力准确数值，但Emax系列的额定电流范围是400A至6300A，分断能力由42kA至150kA（380/415VAC），E3H08的相关参数可能在这个范围内，并且不同的应用场景可能会根据需求进行选型配置。

智能功能 PR121/P E3H08

智能保护脱扣器配有先进的电子元器件，可以度身定制不同的控制和保护方案。还具有新的保护功能和报警功能，并且可能可以通过蓝牙技术连接到外部设备（如手提电脑/笔记本电脑），不过这需要根据具体产品配置确定，E3H08可能具备这样的智能化潜力。

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.
