What type of electrical component is this?

This is a four-position industrial plug designed to create detachable electrical connections in compatible terminal block assemblies. It uses spring-cage terminals for quick, secure conductor connection.

How many connection positions does the plug have?

The plug has four connection positions arranged on a single level.

What is the nominal voltage rating?

The nominal voltage rating is 500 V in accordance with IEC specifications. Ratings under individual approvals may differ, so the applicable installation standard should always be considered.

What current can the plug carry?

The nominal current is 24 A. The maximum permitted current depends on factors such as conductor size, ambient temperature, the number of positions and the connected assembly.

Which conductor sizes can be connected?

The spring-cage terminals accept solid conductors from 0.08 mm² to 4 mm² and flexible conductors from 0.08 mm² to 2.5 mm². This broadly corresponds to AWG 28 to 12 for solid conductors and AWG 28 to 14 for flexible conductors.

What connection technology does it use?

It uses spring-cage connection technology. This provides consistent contact pressure without requiring conventional screw terminals.

What insulation length should be removed from the conductor?

The recommended stripping length is between 8 mm and 10 mm.

Can conductors fitted with ferrules be used?

Yes. Flexible conductors fitted with ferrules, either with or without plastic sleeves, can be used in sizes from 0.14 mm² to 2.5 mm².

Can two conductors be installed in one connection point?

Two flexible conductors of the same cross-section may be connected using an appropriate TWIN ferrule, with a maximum conductor size of 0.5 mm² per conductor.

What are the dimensions of the plug?

The plug measures approximately 20.8 mm wide, 15.8 mm long and 39 mm high. It has a 5.2 mm pitch.

What colour and material is the housing?

The housing is grey and made from polyamide insulating material. It has a UL 94 V-0 flammability rating.

What is the rated surge voltage?

The rated surge voltage is 6 kV. The component is classified for overvoltage category III, pollution degree 3 and insulating material group I.

What operating temperature range is specified?

The specified operating temperature range is -60°C to 105°C, with a maximum short-term operating temperature of 130°C. Assembly and actuation are specified for ambient temperatures from -5°C to 70°C.

Can the connection points be identified with markers?

Yes. The design provides a large marking area and accepts compatible terminal markers, helping installers identify individual circuits clearly.

Can the plug be coded to prevent incorrect insertion?

Yes. Practical coding options can be used to distinguish connectors and reduce the possibility of mating the plug with the wrong compatible terminal position.

Are accessories available for cable retention and identification?

Compatible accessories include strain-relief components, latching elements, insulating sleeves, shield connection clamps, terminal markers and an actuation tool. Accessory compatibility should be checked against the intended connector arrangement.

What is the component's approximate weight?

Phoenix Contact 3040287 weighs approximately 11.83 g per piece, excluding packaging.

What applications is this plug commonly suited to?

It is suited to detachable power, control and signal connections in industrial control cabinets, machinery panels, rail equipment and other systems using compatible pluggable terminal block assemblies.
