Features: 1. imported from Japan for bimetal temperature sensing element, the change in temperature can react quickly, simply and reliably, no arc. ??? 2. No thermal effect of current, temperature, accurate, long life. ??? 3. All imports of environmental materials (by SGS test), with export requirements. Scope: 1. This applies to all kinds of motors, induction cooker, vacuum cleaner, drainage pumps, ballasts, transformers, electric heaters, electric appliances. 2. When using contact temperature installation, should be charged with the product closely aligns the mounting surface appliances. 3. When the installation is not strong to crush or deform the shell, so as not to affect its performance. ? Note: Customers can choose shell and wire according to different needs.
