Description
RTI thermal electrical relay is designed for protecting electric motors from overload, phase unbalance, overcrank condition and rotor jamming. It is installed directly onto KTI and KMI AC contactors. To ensure shortcircuit protection, the unit should be supplied with fuses and modular circuit breakers intended for the correspondent value of rated actuating current. Correspond to the requirements EN 60947-1, EN 60947-4-1, EN 60947-5-1.
Life time:
15 years
Warranty:
5 years
Advantages
- High accuracy of operation.
- Convenient adjustment.
- Wide range.
Design Features
An area provided for marking allows you to make indication of compliance to the scheme, that simplifies the installation.
The possibility of a forced stop of the contactor.
An indicator on the front panel informs about the current state of opening and closing contacts.
Sealing of the transparent cover protecting the setpoint adjustment disk, eliminates an unauthorized access to the setpoints of operating current values.
