RDJ2 Series Thermal Over-load Relay

RDJ2 (LR2) series bimetallic type thermal over-load relay is suitable for the circuit of AC50Hz/60Hz, rated operating voltage Ue:660V, rated current 0.10~630 (A), as the use of over-load, break phase and protection of motor and circuit. The structure and main technique performance index of this thermal relay is the same with LR2 series thermal relay, therefore, LR2 series thermal relay can be entirely replaced by RDJ2 series thermal relay.

Product Introduction

RDJ2 (LR2) series bimetallic type thermal over-load relay is suitable for the circuit of AC50Hz/60Hz, rated operating voltage Ue:660V, rated current 0.10~630 (A), as the use of over-load, break phase and protection of motor and circuit. The structure and main technique performance index of this thermal relay is the same with LR2 series thermal relay, therefore, LR2 series thermal relay can be entirely replaced by RDJ2 series thermal relay.

Usage and its scope of application

Thermal relay with the functions and characteristics of break phase protection temperature compensation, setting current adjusting, optional selection of auto-reset and manual reset, action indication signal, insulation separation of NO, NC auxiliary contacts, small installation section, and various installation mode. Moreover, it has the testing and stop push-buttons, and it can be inspected the action flexibility, has the protective cover that prevent the hand get shocked, safe to use, with the locking device to prevent misoperation etc. This product confirms to : GB14048.4, IEC60947-4-1 etc. standards.

Normal operating condition and installation condition

Ambient temperature: -5°C~+40°C, and the average value within 24h does not exceed +35°C
Altitude of the installation place does not exceed 2000m;
Atmosphere condition: The relative humidity does not exceed 50% when it is at +40°C, it allowed relatively high humidity at the relatively low temperature, for example, the relative humidity reaches 90% when +20°C, and it should take special measurements when there produced the condensation on the product due to the temperature variation.
It should be at the no explosion danger medium, and the medium without the gas that cannot corrode the metal and damage the insulation as well as the places that without conductive dust.
Grade of pollution: 3
Installation category: III
Installation position: installed at the normal position, the gradient between the installation side and the vertical side does not exceed ±5°, and without obvious vibration and impact.
Protection grade: IP 20.
