B4X-15140和B7-15140可调环境温度控制器

      应用…

      电伴热控制

      B4X-15140和B7-15140根据环境温度对管线和容器的防冻电伴热回路进行控制，可调的温控器可控制单个电伴热回路，也可通过接触器对多个回路进行控制。

      B4X-15140…外涂环氧聚酰胺的铸铝NEMA 4X外壳，对温控开关起到防水、防尘、抗腐蚀的保护作用。

      B7-15140…外涂铝漆的铸铝外壳，有NEMA 4（防水和防尘）和NEMA 7/NEMA 9（隔爆）不同规格来保护温控开关。防止误开盖、螺纹并装有密封垫的铝制调节盖，可在外部进行调节。

      B4X-15140温控器经批准可用于普通场所（未分级）；B7-15140经批准可用于普通场所（未分级）和危险（分级）场所。
