2014年2月6日 · IEC 60898-1 relates to a.c. low-voltage circuit breakers for household and similar applications– also known as MCBs (miniature circuit breakers)– which we find in homes, schools, shops, and office electrical distribution switchboards.

2021年11月30日 · EN 60898-1与家用和类似应用的交流低压断路器有关——也称为MCB（微型断路器）——我们可以在家庭、学校、商店和办公室配电配电盘中找到它。 标准规定最大额定电流为125A，最低为几安，额定短路容量（Icn）最大值为25kA。 仅这些基本技术规范就告诉我们两个标准定义的断路器 (CB) 的使用有何不同。 EN 60898-1 和EN 60947-2之间还有更多区别吗？ 是的。 工业用途CB当前所需的额定电压为400 V、440 V、690V或更高的值，最高可达1000V。 将这 …

2024年12月26日 · IEC 60898-1: The Standard for Residential Installations Overview. IEC 60898-1 is designed specifically for low-voltage circuit breakers used in residential and similar environments. These are commonly known as Miniature Circuit Breakers (MCBs). Key Specifications. Rated Voltage: Typically up to 440 V a.c. Rated Current: Up to 125A

2019年7月16日 · Circuit-breakers to BS EN 60898-1 may look identical to those complying with BS EN 60947-2 but they are not necessarily inter-changeable. For example, the BS EN 60898-1 standard describes B, C and D operating curves with ratio to rated current.

60898, the British Standard for circuit-breakers for overcurrent protection for household and similar installations. BS EN 60898-1 (EN 60898-1, IEC 60898-1) & BS EN 60898-2 (EN 60898-2, IEC 60898-2) relate to low-voltage circuit-breakers for use in household and similar installations.

IEC/EN 60898-1 (VDE 0641-11) differentiates between 1, 1+N, 2, 3, 3+N, and 4-pole swit-ching devices. Siemens MCB versions with 1, 2, 3 or 4 poles are equipped with independent overcurrent and short circuit detectors on all poles. In the versions 1+N …

Thanks to IEC 60898-1 they can be handled even by unskilled people. (S200, S200 M, SN200) The K-type characteristic assures best protection and control for circuits like motors, transformer and auxiliary in order to protect damageable elements in the overcurrent range as well as cables and lines and stands out through noiseless tripping.
