Clema SMK222-412

For joining the conductors. The spring clamps of SMK terminals ensure reliable and durable contact. Presence of technological hole allows checking for electrical contact between the conductors. The last digit in designation determines number of conductors that can be joined. The advantage of SMK terminals over other types of electrical connections is secure protection from contact with live parts.Low overheating by passing the rated current. Ability to connect/branch combinations of aluminum and copper conductors. Improved current conductivity of clamps by increasing the volume of metal used.Number of clamp positions: 2 Nominal cross section: 4,0 Colour: EV000270 Nominal voltage: 450 Nominal current: 32 Connectable conductor cross section fine-strand without cable end sleeve: 0,08...4 Connectable conductor cross section solid-core: 0,08...2,5 Connectable conductor cross section multi-wired: 0,08...4 Type of electrical connection: EV005755 Type of electrical connection 2: EV005755 Connection position: EV001224 Operation temperature: -25...85 Length: 12.7 Nominal operating AC voltage Ue: 400 Nominal DC operating voltage Ue: 220 Rated insulation voltage Ui: 660 Degree of protection (IP): EV006405 Mechanical Execution Group: EV009088 Width: 21.0 Height: 14.5 Nominal Attachment Capacity: 0,08...4 Relative air humidity: ≤ 90% Maintainability: EV000494 Ambient class: IEK_V0000009
