Introduction

The EKRS sereies rotary switch mainly applies to 440V and below,AC 50Hz or 240V and below DC circuits. For breaking and closing, change-over of circuits unfrequently manual operation. And the typical application are: control switch of 3 phase motors, control switch of switch gear, control switch of instruments,and change-over switch of machinery and welding machine.

● The series comply with the IEC 60947-3,IEC 60947-5-1.
● The EKRS26 series have 8 current ratings: 10A,20A,25A,32A,63A,125A ,160A and 315A.
● The EKRS26 series rotary switch were designed for multiple functions, wide variety of applications.
● The EKRS26-10,EKRS26-20,EKRS26-25,and EKRS26-32F have finger protection terminals.
● Both of them are applicable in circuits when an physical control is required.
● We can equip protective box for 20A,25A,32A and 63A.

Working conditions

● Ambient temperature does not exceed 40℃, and the average temperature, measured over a period of 24 hours, do not exceed 35℃
● Ambient temperature should not be below -25℃
● Should Not be installed over 2000m above sea level
● The humidity should not exceed 50% when the ambient temperature is 40℃ and higher humidity is allowed for lower temperature

Installation conditions

● A clean environment is required
● Please follow our manual
