2. Key characteristics
Insulation and flame retardant: The material is Polyamide 66 (PA66), and the flame retardant rating is UL 94 V0 (35/70/120mm ²), V2 (240mm ² and 10mm ² small specifications)
Voltage parameters: rated voltage 1000V, rated impulse voltage 8kV, pollution level 3
Installation method: Snap on installation on DIN rail, disassembly requires pushing back the movable buckle and tilting it; The grounding terminal block contacts the DIN rail through the grounding foot
Common connection: achieved by inserting 2/3/4 jumper wires into the jumper slot, and the jumper wires are adapted to the rated current of the terminal block
