EN60335-2-21中22.106也是这样描述的,不过按照thermal cut-out的定义,开关上的漏电保护开关肯定不能算作热熔断器器,同时即使退一步说,它也不与24.2冲突,24.2的要求并非说软线上面不能有开关,EN60335-1中原句如此描述:, D3 R1 T( F/ g, R l( z% k0 v
24.2 Appliances shall not be fitted with

它的意思应该表示器具上不能使用这样的元件,在它失效时不能引起固定布线上保护装置动作,0 j. C+ h8 h/ k$ G$ V. p; J4 U1 r

所以至于LZ的那个器具是否有全极断开的热熔断器,还得去核查,也许它本身并没有。 |
