It is a blue, double-level DIN rail terminal block designed to provide two separate connection levels within a compact control panel footprint. It uses screw-clamp connections and has four connection points.
Under IEC ratings, the terminal block has a nominal current of 32 A and a nominal voltage of 500 V. Applicable ratings may differ according to the approval standard and installation conditions.
The connection range for solid and flexible conductors is 0.2 mm² to 4 mm², equivalent to AWG 24 to AWG 12. Flexible conductors fitted with ferrules and plastic sleeves can range from 0.25 mm² to 2.5 mm².
Phoenix Contact 3216053 uses M3 screw connections. This established connection method provides secure conductor clamping for industrial control cabinets, distribution panels, and machine wiring.
The specified conductor stripping length is 8 mm. The M3 terminal screws should be tightened to between 0.6 Nm and 0.8 Nm.
The terminal block can be mounted on NS 35/7.5, NS 35/15, and NS 32 rails. These include standard 35 mm DIN rail profiles and the 32 mm G-profile rail.
The unit is 6.2 mm wide and 67 mm long. Its installed height is 62 mm on an NS 35/7.5 rail, 69.5 mm on an NS 35/15 rail, and 67 mm on an NS 32 rail.
It provides two levels and four connection points. This double-level arrangement helps increase wiring density without requiring additional DIN rail length.
The specified ambient operating temperature range is -60°C to 85°C. Assembly and conductor actuation are specified for ambient temperatures from -5°C to 70°C.
The housing is made from polyamide insulating material and has a UL 94 V-0 flammability classification. The terminal block is blue for straightforward circuit identification within an enclosure.
Yes. Two conductors of the same cross-section can be connected within the specified limits. Solid or stranded conductors may range from 0.2 mm² to 1.5 mm², while compatible twin-ferrule arrangements range from 0.5 mm² to 1.5 mm².
Compatible accessory categories include end covers, spacer and partition plates, end clamps, insertion bridges, fixed bridges, jumpers, test plugs, test sockets, and terminal markers. Accessory selection should match the 6.2 mm terminal width and the intended rail arrangement.
Compatible options include the EB 2-6 two-position bridge, EB 3-6 three-position bridge, and EB 10-6 ten-position bridge. These have a 6.2 mm pitch and can be used to create common electrical connections between adjacent terminals.
It is commonly suited to compact industrial panel wiring, control cabinet connections, signal distribution, machine wiring, and other installations where two independent circuits must be arranged vertically to conserve rail space.
Yes. The design includes a large labeling area and accepts compatible 6 mm terminal marking systems, including blank, preprinted, and custom-labeled marker strips.
The terminal block is designed in accordance with IEC 60947-7-1. It also carries multiple international approvals, although the permitted current, voltage, and conductor range can vary between approval systems.
