Tùy chỉnh AC Bimental Magnetic Overcurrent Relays Phạm vi hiện tại 0.1 - 22A 3P Loại tiêu chuẩn
UKH-22/3 OEM /ODM acceptable Custom AC Bimental Magnetic Thermal Overload Relay Current range 0.1~22A 3P Standard type General: Bimetallic thermal overload relays use a bimetallic strip to mechanically open the contacts. Bimetallic strips consist of two conjoined pieces of metal which expand at ...
Bộ chuyển tiếp Contactor Relay GTH-85
Custom AC Bimental Magnetic Thermal Overload Contactor Relay GTH-85 Bimetallic thermal overload relays use a bimetallic strip to mechanically open the contacts. Bimetallic strips consist of two conjoined pieces of metal which expand at different rates when exposed to heat. This difference forces the ...
Ổn áp quá tải nhiệt động cơ GTH-12M, bảo vệ quá tải
GTH-12M Mini Motor Thermal Overload Relay , Overload Protection Relay Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a normally closed (NC) relay. ...
GTH40 UL Tấm truyền nhiệt quá nhiệt từ trường điện Rơle bảo vệ điện
GTH40 UL Magnetic Thermal Overload Relay Electrical Protective Relays UKH series thermal overload relays apply to circuit of AC 50Hz or 60Hz, rated voltage to below 660V and rated current . 1A-800A for AC motor overload and open-phase protection during long time or intermittent long time service, ...
