Product Description

T45 thermal overload relay

Application

T45 thermal overload relay are suitable for overload and phase-failure protection of AC motors with frequency of 50/60Hz, voltage up to 690V, current up to 0.16-500A under 8-hours duty or uninterrupted duty.
Functions provided by these relays, are phase-failure protection, temperature compensation, ON/OFF indication, and manual/automatic reset.
Applicable Standards: National Standard: GB 14048, International Standards: IEC 60947-4-1.
The relays can be mounted onto contactors or installed as single units.

Operating Conditions

Ambient temperature: -5 ~+55 degree centigrade and the average temperature no more than +35 degree centigrade in 24 hours.
Atmosphere: Comparative humidity no more than 50% at max +40 degree centigrade, and it may be higher at a lower temperature. The lowest average temperature no more than +20 degree centigrade in the wettest month.
The maximum average comparative humidity of this month could not exceed 90%, The change of temperature leading to dew on the product must be considered.
Class of pollution: Class 3.
The slope between installation surface and vertical surface could not exceed plus and minus 5 degree
Keeping away from explosive, corrosive and electric atomy.
Keeping dry.
The product should be used and installed at certain place without any shock, vibration etc.
