Product Introduction

RDR5 series Thermal Relay(Relay) is mainly applied to circuit of AC50/60Hz, Rated operate voltage up to 690V, Rated impulse withstand voltage

Uimp(kv):8, Rated current 0.1-93(A), as long-time work or discontinuity long-time circuit and motor overload breaking, protecting.

Standard: IEC 60947-4-1 GB14048.4

Structure and working principle
The actuating mechanism of the thermal relay is a spring type quick action jumping structure,and its internal structure diagram is shown in Figure 1
Structure function
■With phase failure protection
■With continuous adjustable setting current device
■With temperature compensation function
■With action indication
■With action indication
■With testing agency

Fig.1 Electrical schematic diagram
of internal structure
Working principle

■With stop button
■With manual and automatic reset buttons
■Electrically separable 1NO+1NC contact

The bimetal elements of the thermal relay are connected in series in the main circuit. When the line current increases, the bimetallic element is heated and bent to a certain extent to push the sliding plate,and the normally closed contact is separated from the push rod by compensating the bimetallic element. Ensure that the motor is out of phase and overload is effectively protected
