Eaton Cutler-Hammer
Terminal Blocks

Product Family Overview
The XB Series of IEC Terminal Blocks from Eaton's electrical business offers a full line of terminal blocks complete with universal accessories across three connection technologies, screw, spring cage and Insulation Displacement Connection (IDC), reducing inventory and logistic costs.

Eaton now also offers custom rail assemblies along with ECHART Rail Assembly Software, which allows you to build your custom rail assembly and provides dimensionally accurate drawings.

Application Description
XB Series terminal blocks contain high-grade, strain-crack and corrosion proof copper alloys to prevent electrolytic corrosion and rusting. The metal surfaces are protected with a lead-free, galvanic nickel or tin plating. The electrical conductivity permits only a low temperature rise.

Features

  • Global Acceptance - designed to worldwide standards
  • Flexible Plug-In Bridge System - All XB Series use the same bridge system and have two bridge shafts arranged in one line
  • Marking Areas - Generously sized surface areas for labeling
  • Testing System - Test plugs make contact in one of the easily accessible bridge shafts

Construction

  • Insulation Material - Polyamide 6.6
  • Clamping Body - Tin Plated Copper
  • Flammability Rating - UL 94 VO
  • Continuous Operating Temperature - 40°C - 125°C

Standards and Certifications

  • UL recognized: File No. E67464
  • Eaton DIN terminal blocks are ISO 9001 certified
  • CE
  • LVD:
    • EN60947-7-1
    • EN5094-1
    • EN60947-1 A11
    • EN60529

Screw Connection Terminal Blocks
The XBUT Series utilizes a screw connection system that is accepted worldwide and is suitable in most applications. The maintenance-free connection provides the reliability you expect from Eaton.

Application Description
The screw locking maintenance-free design prevents the screws from backing out so tightening of the terminal screws is not necessary to ensure proper operation. Copper wires can be clamped without pre-treatment or ferrules can be used for splicing protection. Multiple conductors can be connected in the same clamping mechanism, saving space.

Features

  • Maintenance-free connections
  • Global Acceptance
  • Multi-conductor connections
  • Flexible plug-in bridge system
  • Large surface area for marking
  • Standardized testing system

Spring Cage Terminal Blocks
The XBPT Series incorporates a spring cage connection system for use in applications that are sensitive to vibration. The spring mechanism exerts a constant force on the wire, resulting in a vibration-proof, gas-tight connection. The front connection design allows the screwdriver and wire to enter from the same direction, allowing wiring in tight spaces.

Application Description
The connection point is opened with a standard screwdriver. After a stripped wire is inserted, the screwdriver releases the spring and a secure connection is made. Spring cage terminal blocks offer a large insertion space so that wires with ferrules can also be inserted.

Features

  • Vibration-resistant
  • Global Acceptance
  • Multi-conductor connections
  • Flexible plug-in bridge system
  • Large surface area for marking
  • Standardized testing system

Pluggable Spring Cage Terminal Blocks
The pluggable spring cage connection terminal blocks allow signal and power wiring to be made pluggable. This complete pluggable system has a patented spring that provides maximum connection space in a space-saving design. The pluggable system accommodates stranded conductors with a nominal cross-section of 2.5 mm², with or without ferrules.

Application Description
For applications requiring pluggable wiring up to a rated current of 32A and a rated voltage of 800V. The integrated overspring meets the most stringent vibration requirements. Also ideal where safety is a concern and flexibility is required. The basic terminal blocks and the plugs are finger-safe which also means the supply voltage can be input via either the terminal blocks or the plugs. With the XBAPSC receptacles, plug-in contacts can be accommodated safely in cable ducts and distributor shafts using minimal space. A test hole can accommodate a 2.3 mm diameter test plug in each receptacle, providing a practical solution. The XBAPSP plugs are intended for connecting one wire while the XBAPSPDB plugs are designed to connect two wires and an optional bridge.

Features

  • Space-saving design
  • Powerful contact
  • Finger-safe

Insulation Displacement Connection (IDC) Terminal Blocks
The XBQT Series terminal blocks reduce wiring installation time and labor, especially in high-volume applications. The XBQT Series allows for wire to be connected without stripping. The quick connection provides up to 60% reduction in wiring time. One turn of a standard screwdriver results in a simple, fast, and reliable connection. IDC terminal blocks are suited for applications in automated equipment and machine tools, packaging and material handling machinery, railway and mass-transit systems, petrochemical, and other applications requiring high-volume connections for low-voltage control and signal circuitry where labor cost reduction and ease of assembly is desired. These terminal blocks are designed for long-term use under demanding conditions.

Application Description
The XBQT Series is operated with a standard screwdriver. The switching states are clearly signaled by engagement points in the start and end positions. Solid and stranded wires of 0.25 to 2.5 mm can be wired without the use of ferrules. Stripping the wire is not required. The insulation is cut open within the terminal block when it is properly connected. The wire is securely placed in the end position where it makes large-area, gas-tight contact.

Features

  • Quick connection capability
  • Global Acceptance
  • Flexible plug-in bridge system
  • Large surface area for marking
  • Standardized testing system

Miniature Terminal Blocks
The XBM Miniature Series terminal blocks have a connection cross-section of 1.5 mm² and mount on 15 mm DIN rail. There is an opening for bridging with a fixed bridge in the center of the terminal block. These miniature terminal blocks are compatible with the same accessories as the larger terminal blocks, including marking tags, end covers, end stop and ground blocks.

Thermal Miniature Circuit Breakers
The XB Series thermal miniature circuit breaker offers convenient overload protection. This space-saving single-pole circuit breaker, available up to 10 Amps, can be inserted into a basic terminal block, XBUK6FSI, which is available with or without light indication. The XBATCP combines the re-closing capability of a circuit breaker with the overload protection of a fuse. The integrated switching function makes it possible to switch the circuit breaker back on immediately, guaranteeing system availability. The device can also be used for switching purposes. The plug-in design allows for quick and efficient replacement.
