DIN RAIL TERMINAL BLOCKS Rail-type terminal blocks provide up to 380A and high current terminals up to 1000V, making them suitable for a wide range of environments.they can be fixed on the common U/G-shaped rails. Besides, the stackable design of single Pole allows us to install the products of different wring capacitance on the common rails together. The insulator is made from PA66 which is characterized by good toughness and flame retardancy; the wire cage clamping structure of brass alloy prevents the products from adverse circumstances such as moisture and salt spray. The product design conforms to international standards such as IEC60998 and UL1059. Has obtained the US UL certification.
