ABB Emax 斷路器及其零附件均符合國際 IEC60947, EN 60947 、CEI EN 60947 和 IEC 1000 標(biāo)準(zhǔn)，以及相關(guān)的EC指令 : · "低壓指令” (LVD) no. 73/23 EEC · "電磁兼容指令” (EMC) no. 89/336 EEC此外，一系列的 Emax 斷路器更符合 UL 1066 標(biāo)準(zhǔn)。

The operating mechanism belongs to the energy storage type, that is, the spring operated with pre stored energy. The spring energy storage can be operated manually by the front handle or by the electric motor operated by a gear type motor. The split spring is stored automatically during the closing operation.
By installing and closing the coil in the operating mechanism, and by using a gear motor to store the energy of the spring, the circuit breaker can perform remote control operations, and, if necessary, monitor the system coordination.
In the following cycle of operation, there is no need to re store the spring:
At the beginning, the circuit breaker is in O, and the spring is in the energy storage state: switch on and off;

E2S2000 R2000 PR121/P-LI 3P 智能型萬能式斷路器適用交流50Hz，額定電壓380V、660V，額定電流為200A-6300A的配電網(wǎng)絡(luò)中,主要用來分配電能和保護線路及電源設(shè)備免受過載、欠電壓、短路，單相接地等故障的危害，該斷路器具有多種智能保護功能，可做到選擇性保護，具動作精確，避免不必要的停電，提高供電可靠性。 萬能式斷路器用來分配電能和保護線路及電源設(shè)備的過載、欠電壓、短路等，在正常的條件下，可作為線路的不頻繁轉(zhuǎn)換之用。1250A以下的斷路器在交流50Hz電壓380V 的網(wǎng)絡(luò)中可用作保護電動機的過載和短路。在正常條件下還可作為電動機的不頻繁起動之用。
