The advantages at a glance
Convenient connection
Thanks to the screw connection principle with spring-guided screw, you can wire conductors quickly and easily with ring cable lugs. The integrated spring washers ensure vibration-proof and maintenance-free connection.
Quick and easy wiring
Thanks to the double Push-in connection, you can wire two conductors to one potential – easily and without tools.
Easy potential distribution
Using two-pos. plug-in bridges, any number of terminal blocks can be quickly connected to form a potential distribution block.
Insertion bridges
Touch-proof insertion bridges offer an additional bridging option.
Easy testing
The easily accessible 2.3 mm test points offer a convenient testing option, e.g., in the case of maintenance or servicing.
Integrated touch protection
The BT terminal housings are touch-proof. This means that an additional terminal strip cover is not required.
Maximum overview
Using continuous marker strips, the terminal blocks can be marked over a large surface, and each terminal point can be marked clearly. The transparent design of the strips means you retain a clear overview when bridging.
Fast configuration
CLIP PROJECT enables you to configure BT terminal strips quickly, conveniently, and without any errors. Direct data exchange with all common CAE systems, along with the creation of the complete project documentation, make this configuration software unique.
High-quality hand tools
Whether for cutting, stripping, crimping, screwing or measuring – Phoenix Contact offers the ideal tool for every application.
Covering hoods
Covering hoods are available for the BTO terminal block variants.
Free choice of connection technologies
The BT barrier terminal blocks are available with various connection technologies and as hybrid versions. Combine the connection technologies and benefit from the individual advantages for the control cabinet and field connection side.

With Push-in multi-conductor terminal blocks from Phoenix Contact, you can connect up to four conductors with individual wiring at each terminal point. |
Customized options: BT barrier terminal blocks are available for all of your applications as DIN rail or direct mounting terminal blocks.
Easy DIN rail mounting
The barrier terminal blocks can be easily snapped onto all NS 35 DIN rails and moved sideways.
Easy mounting on DIN rail end
Easy to remove without tools – just tip slightly to the side to unlock the terminal block.
Removal from the DIN rail
Can be easily lifted off.
Easy direct mounting
The barrier terminal blocks for direct mounting can be arranged to create individual terminal blocks and secured with the integrated flange and cover flange.
Direct mounting – flange fixing
To ensure optimum fixing stability, the terminal blocks can be fixed at any point within a terminal block without loss due to separation.
Direct clamping on DIN rail
Alternatively, the terminal blocks can be snapped onto NS 35 DIN rails. When doing so, pay attention to the mounting screws on the DIN rail.
Screw connection principle with spring-guided screw
Convenient and safe ring cable lug connection:
- Convenient conductor connection, thanks to captive and spring-loaded connection screws
- Automatic screw centering, thanks to optimum guidance in the terminal housing
- Vibration-proof and maintenance-free screw connection, thanks to integrated spring washer
- Simple multi-conductor connection
- Considerable conductor pull-out forces due to high contact force and large contact surfaces
Connection principle
Simple multi-conductor connection
The clamping space is designed for a two-conductor connection with ring cable lug or fork-type cable lug.
Convenient conductor connection
The clamping screw is captive and is spring-guided in the terminal housing and centered. It can be conveniently tightened in this way.
Reliable contact
Vibration-proof and maintenance-free screw connection, thanks to integrated spring washer.
Push-in connection technology
Easy application – high-performance connection:
- Direct, tool-free conductor connection for rigid conductors or conductors pre-assembled with ferrules
- The special spring profile enables easy insertion of conductors with ferrules starting from 0.25 mm² combined with maximum conductor pull-out forces
- The push button permits easy conductor release using any type of tool, without direct contact with live parts
- For connecting flexible conductors without ferrules starting from 0.14 mm², the button simply needs to be actuated during insertion
Connection principle
Tool-free insertion
Rigid conductors or conductors with ferrules can be inserted directly into the terminal block without using tools.
Reliable contact
The contact spring is opened automatically when the conductor is inserted. This ensures high contact and conductor pull-out forces. Conductors with a nominal cross section can be wired with ferrules and insulating collars.
Connecting a flexible conductor
Flexible conductors without ferrules are connected using the push button.
Competence in connection technology – Quality is our top priority
Barrier connection technology is a safe and reliable solution in any application. This connection technology is subjected to tests which go beyond the basic standard, enabling it to be used in all sectors of industry, such as energy supply, transportation technology, the chemical industrial, and shipbuilding.
Vibration-resistant contacting
The barrier connection technology is tested for maximum vibration and shock resistance. The test runs in three axes through a frequency range of 5 Hz to 150 Hz at an acceleration speed of up to 5.72 m/s². Barrier terminal blocks meet this stringent vibration requirement.
Maximum conductor pull-out forces
Requiring up to 50% lower conductor insertion force, Push-in connection technology achieves 145 N in the conductor pull-out test of a 1.5 mm² terminal block with a 1.0 mm² conductor, for example, where only 35 N is required in accordance with the standard.
Gas-tight contact
A test method describes a corrosion test in condensation climates with an atmosphere containing sulfur dioxide and salt mist. The Push-in connection technology creates high-quality, gas-tight connections that cannot be impaired even by aggressive substances.
High-performance contacting
Conductor contact points must, in practice, also be capable of withstanding short-circuit currents, without sustaining any damage, until the relevant safety equipment cuts off the power. Maximum contact reliability, even under extreme overload is illustrated with a hybrid terminal block.
Long-term contact stability
Using a two-chamber method, the barrier terminal blocks are subjected to sudden temperature changes from -55°C to +100°C. They are designed for extreme durability even under difficult temperature conditions. Plastic as well as metal parts provide sufficient safety reserves.
Reliable contact
The pivotal role of the metal parts of electrical connections becomes particularly apparent in aggressive environments. A test method describes a corrosion test in condensation climates with an atmosphere that contains sulfur dioxide. Screw and Push-in connection technology create high-quality, gas-tight connections that are not impaired even by aggressive substances.
