## Long description

The Phoenix Contact ST 6 BU Through Terminal Block Blue is an essential electrical component designed for secure and efficient wire connections in industrial control panels and automation systems. Featuring spring-cage connection technology, this terminal block provides a reliable, vibration-resistant interface that simplifies circuit organization and reduces maintenance time. Its durable blue housing allows for clear visual identification of neutral or specific circuit paths within complex electrical installations, supporting optimal space utilization on standard DIN rails.
Advantages
The spring-cage connection method ensures quick and tool-free insertion of rigid and flexible conductors with ferrules, significantly reducing wiring time during assembly. The high-quality materials used in this feed-through terminal block guarantee stable electrical contact and long-term mechanical durability under demanding industrial conditions. Its compact 8.2 mm width helps maximize rail space, while the blue color aids in proper circuit differentiation and safety compliance.
Suitable for
Industrial control panels and automation systems
Electrical distribution and switchgear installations
Machinery manufacturing and plant engineering
Signal and power circuit organization
When it may not be suitable
This through terminal block is not designed for direct outdoor installation without a proper protective enclosure shielding it from moisture and dust. It is also unsuitable for wire cross-sections exceeding 10 mm² or falling below 0.2 mm², as outside this range the spring-cage mechanism will not maintain a secure connection.
Key specifications
Nominal voltage: 1000 V
Nominal current: 41 A
Connection method: Spring-cage connection
Number of connections: 2
Conductor cross section: 0.2 mm² to 10 mm²
AWG range: 24 to 8
Width: 8.2 mm
Color: Blue
Mounting type: NS 35/7,5 and NS 35/15 DIN rails
How to use
Mount the terminal block securely onto a compatible DIN rail such as NS 35/7,5 or NS 35/15 by snapping it into place. Prepare the electrical wire by stripping the insulation to the recommended length, and if using stranded wires, attach a suitable ferrule. Insert the prepared conductor firmly into the spring-cage opening until it is fully seated and securely clamped by the internal spring mechanism. To release or remove the wire, insert a standard operating tool into the actuation shaft to open the spring clamp.
What to consider before purchase
Verify that your conductor cross-sections fall within the 0.2 mm² to 10 mm² or 24 to 8 AWG range.
Ensure the electrical load does not exceed the nominal voltage of 1000 V and nominal current of 41 A.
Check that your enclosure provides adequate environmental protection if used in harsh industrial settings.
Confirm that your mounting rail type matches the supported NS 35/7,5 or NS 35/15 dimensions.
Usage recommendations
Always isolate the electrical circuit from the power supply before installing, servicing, or modifying any terminal block connections. Use appropriately rated insulated hand tools and follow local electrical safety regulations and wiring standards during assembly.
