Why Choose the WAGO 2004-1201 TOPJOB S Feed-Through Terminal Block?

The WAGO 2004-1201 is a compact and reliable 2-conductor feed-through terminal block from the WAGO TOPJOB S 2004 Series, designed for secure conductor connections in industrial control panels, machinery and electrical distribution systems. With a nominal conductor cross-section of 4 mm², it provides a practical solution for medium-current circuits while occupying only 6.2 mm of DIN rail width.

Featuring WAGO's proven Push-in CAGE CLAMP® connection technology, the 2004-1201 allows suitable solid and ferruled conductors to be inserted directly while maintaining consistent spring pressure on the conductor. This provides a secure, vibration-resistant and maintenance-free connection without the routine retightening associated with conventional screw terminals.

The terminal provides two conductor connections on one electrical potential and is rated at 800 V and 32 A according to IEC ratings. It is suitable for Ex e II applications, supports side and centre marking and mounts onto standard 35 × 15 mm or 35 × 7.5 mm DIN rails, making it highly versatile for professional industrial installations.

Key Advantages

  • Compact 2-conductor feed-through terminal block for industrial wiring.
  • 4 mm² nominal cross-section with conductor capacity up to 6 mm² depending on conductor type.
  • Push-in CAGE CLAMP® technology enables fast and secure conductor termination.
  • 32 A IEC rated current for medium-current control and distribution circuits.
  • 800 V IEC rated voltage for demanding electrical installations.
  • Suitable for Ex e II applications and standard industrial environments.

Key Features

  • WAGO TOPJOB S 2004 Series rail-mounted terminal block.
  • 2-conductor through / feed-through configuration.
  • 4 mm² nominal conductor cross-section.
  • Push-in CAGE CLAMP® spring-pressure connection.
  • 32 A rated current according to IEC ratings.
  • 800 V rated voltage according to IEC ratings.
  • 8 kV rated impulse voltage.
  • One level with one electrical potential.
  • Front-entry conductor wiring for convenient panel assembly.
  • Side and centre marking options for clear circuit identification.
  • Compatible with DIN 35 × 15 mm and DIN 35 × 7.5 mm rails.
  • Grey housing for standard feed-through circuit identification.

Reliable Push-In Connections for Industrial Wiring

Feed-through terminal blocks provide a convenient method of joining two conductors at a common electrical potential while keeping industrial wiring organised on the DIN rail. The WAGO 2004-1201 combines this straightforward circuit function with Push-in CAGE CLAMP® technology, maintaining consistent spring pressure on the conductor for reliable electrical contact even where machinery is exposed to vibration.

Suitable solid and ferruled conductors can be pushed directly into the connection point, helping reduce wiring time during control-panel assembly. Its 6.2 mm width, broad conductor range, high electrical ratings and compatibility with TOPJOB S marking and jumpering accessories make the 2004-1201 a versatile choice for industrial automation, switchgear and machine-building applications.

Typical Applications

  • Industrial control panels and control cabinets.
  • Machine building and factory automation systems.
  • PLC and process-control wiring.
  • Electrical switchgear and distribution assemblies.
  • Power and control circuit connections.
  • Hazardous-area installations requiring suitable Ex e II terminal equipment.
