EOCR-SS電子過載沖擊保護器是韓國三和SAMWHA EOCR株式會社于1981年研發并推入市場，是開創電子式替代傳統熱繼電器的企業，產品推出后得到客戶的*。具有靈敏度，數據等特點。由于其安裝調試方便等特點已逐步替代市場上傳統的過載保護方式。

韓國三和SAMWHA EOCR株式會社于2001年被電氣品牌施耐德收購，并成立施耐德電氣韓國有限公司EOCR事業部，隨后產品包裝等也更新為Scheneider統一包裝標識。

為了更好的適應現場環境的需要，EOCR-SS產品進行不斷升級和提升，現已推出全新的系列產品，產品供電電源電壓更寬24-240VAC/DC,380-440VAC，將之前的安全模式分離型產品統一到新系列產品中。面板前段設置安全模式開關，客戶可根據現場進行自行調整。
