EBS1TR-25 new under voltage relay

EBS1TR Series overload thermal relay apply to circuit of AC 50Hz or 60Hz, rated voltage to below 660V an d rated current 0.1~93A for AC motor overload and single phase protection during long time or intermittent long time service, which can also protect three phase serious imbalance and long starting time of motor or long time operation, can also used for corresponding AC Contactor for electromagnetic starter.
Structural features(under voltage relay):

1. 3-phase bimetal type

2. with overload and open-phase protection

3. with setting current continous adjustable appratus

4. with temperature compensation

5. with action indication

6. with testing mechanism

7. with stop button

8. with manual and automatic reset button

9. with electricity separably normal open and normal cloased contacts

10. installaion method: plug installation with contactor or independent insallation.

Normal Application and Installation Conditions ( Thermal Relay )

1. Ambient temperature: The upper limit shall not exceed +40°C; the average value within 24 hours shall not exceed +35°C; the lower limit shall be not less than -5°C

2. Atmosphere conditions: Relative humidity shall not exceed 50% when the ambient temperature is +40°C. Higher relative humidity is permissible at lower temperature, for example, it can reach 90% at 20°C. Special measures should be taken to address the dew occurred occasionally due to temperature changes.

3. Altitude: Installation altitude shall not exceed 2000m

4. Anti-pollution degree: Three

5. Installation category: Three

6. Installations conditions: Install at proper working position, slant of contactor mounting surface shall not exceed±5°C. Thermal relay shall be installed in places with no obvious shake or shock.

7. Environment protection: Sufficient consideration of enviro-nmental protection factors has been taken in design process by adopting retrievable and naturally degradable materials in components.
