关于BUSSMANN FWH-70Ba至FWH-100Ba型号后缀更改的通知-2022-04-04
Eaton Bussmann系列高速熔断器,后缀-a表示熔断器的更新版本。
在对Eaton Bussmann系列高速熔断器FWH-70Ba至FWH-100Ba进行内部更改,并与UL进行了讨论之后,Bussmann对其作出了如下变更:
| 旧型号 | 旧的最低分断能力 @500 V a.c. |
新型号 | 新的最低分断能力 @500 V a.c. |
| FWH-70Ba | 140A | FWH-70Bc | 210A |
| FWH-80Ba | 160A | FWH-80Bc | 240A |
| FWH-90Ba | 180A | FWH-90Bc | 270A |
| FWH-100Ba | 200A | FWH-100Bc | 300A |
这一变化将在2022年4月1日之后生产的熔断器上实施,所有订单随后将转换为以后缀-c结尾的型号。
Eaton's Bussmann series high speed fuses with a suffix -a denotes the generation of the fuses.
Following internal changes to the Eaton's Bussmann series high speed fuses: FWH-70Ba through to FWH-100Ba and discussionswith Underwriters Laboratory (UL), Eaton has changed the suffi x of the range of fuses as seen below:
| Old catalogue number | Old minimum breaking capacity @500 V a.c. Amps (A) |
New catalogue number | New minimum breaking capacity @500 V a.c. Amps (A) |
| FWH-70Ba | 140A | FWH-70Bc | 210A |
| FWH-80Ba | 160A | FWH-80Bc | 240A |
| FWH-90Ba | 180A | FWH-90Bc | 270A |
| FWH-100Ba | 200A | FWH-100Bc | 300A |
This change will be implemented on fuses produced from 1st April 2022 and all orders will subsequently be converted to catalogue number ending with suffix -c.
The datasheet will be updated to reflect the change in designation and increased minimum breaking value. Please note no other changes to published data have been impacted.
