EKR5 Series Recloser for RCCB | Switch / RS485 Control + Auto Reclose
EKR5 Series is a recloser for RCCB supporting switching input control or RS485 (MODBUS-RTU), with optional Type R automatic reclosing (up to 3 attempts, intervals 10s / 60s / 300s). Power supply options: AC230V (A1) or DC24V (D1). It enables remote closing and opening of compatible ETEK RCCBs, with manual/automatic mode selection, LED status indication and mechanical padlock for onsite safety. Module width only 18mm; dimensions 84×18×78mm. Matching products: EKL6-100, EKL6-100B, EKL6-63EV. Typical applications: home smart power distribution and photovoltaic equipment. Main order models with product photos: EKR5-A1CR, A1SR, D1CR, D1SR.

Product Profile
Product Profile
EKR5 Series Recloser is a reclosing device compatible with switch control and RS485 remote control, designed for use with RCCBs. It features an automatic reclosing function that attempts to restart up to three times. If a line protection device trips due to manual opening, short circuit, leakage, or overload, the EKR5 will automatically attempt to restore power, enhancing the reliability of the power supply system. This device is extensively used in areas such as home smart power distribution and photovoltaic equipment.
