Products
EBS1TR Series overload relays apply to the circuit of AC 50Hz or 60Hz, rated voltage to below 660V and rated current 0.1A~93A for AC motor overload and single phase protection during a long time or intermittent long time service, which can also protect against three-phase serious imbalance and long starting time of motor or long time operation. It can also be used for corresponding AC contactors for electromagnetic starters.
This product has an innovative, elegant appearance and a small installation area, with functions such as temperature compensation, action indication, automatic and manual reset, and stop with steady and reliable performance. Thermal relays can be combined/connected with a contactor or installed separately.
Standard: IEC 60947-4-1.
