ABB DYSF118B 61430001-XG
Product introduction
The DYSF118B 61430001-XG is a heavy-duty terminal connection module from ABB, engineered to handle higher current and voltage requirements in industrial control systems. As a robust alternative to the DYTP123A, this module is designed for applications where larger wire sizes and secure, torque-controlled connections are essential—such as power distribution panels, motor control centers, and high-power industrial machinery.
While sharing the core function of simplifying wiring connections with the DYTP123A, the DYSF118B distinguishes itself with screw clamp terminals that provide precise torque control, making it ideal for high-vibration environments where connection integrity is critical. Its higher current and voltage ratings enable it to serve as a bridge between heavy-duty field devices (e.g., large motors, contactors) and control modules like the PCD235C101, ensuring reliable power transmission and signal integrity in demanding industrial settings.
Core advantages and technical highlights
High-power handling capability
With a rated current of 40 A per terminal (vs. 25 A in the DYTP123A) and a maximum voltage of 1000 V AC/DC (vs. 600 V), the DYSF118B is built to manage heavy-duty electrical loads. This makes it suitable for connecting large motors, heating elements, and power distribution components. In a steel mill’s motor control center, for example, it can reliably handle the high currents from 50 HP motor starters, ensuring stable power delivery without overheating.
Torque-controlled screw terminals
Unlike the tool-free spring clamps of the DYTP123A, the DYSF118B features screw terminals with a specified torque range (0.8 – 1.2 Nm). This allows for precise, repeatable connections, critical in applications where vibration or thermal cycling could loosen connections. In a reciprocating compressor system, the controlled torque ensures that power leads to the compressor motor remain secure, preventing arcing and potential equipment damage.
Accommodates larger wire sizes
The module supports wire sizes from 1.5 to 6 mm², significantly larger than the DYTP123A’s 0.5 – 2.5 mm² range. This enables direct connection to heavy-gauge power cables without the need for adapters. In a solar farm’s inverter station, it can connect 6 mm² DC cables from solar panels to the inverter, eliminating junction points that could introduce resistance or failure risks.
Enhanced thermal resistance
Constructed from polyester (PET) insulation material, the DYSF118B withstands higher operating temperatures (up to 90°C) compared to the DYTP123A’s 85°C. Its material composition also offers superior resistance to oils, solvents, and industrial chemicals, making it suitable for use in automotive manufacturing plants or chemical processing facilities where exposure to such substances is common.

Typical application scenarios
Motor control centers
In an industrial motor control center, the DYSF118B connects 40 A contactors to overload relays and power cables. Its screw terminals, tightened to the specified torque, ensure secure connections even during motor startup surges. The red/black color coding helps technicians quickly identify power inputs and motor outputs, reducing wiring errors during maintenance.
Power distribution panels
In a commercial building’s main distribution panel, the module links circuit breakers to busbars and branch circuits. Its 1000 V rating allows it to handle the building’s 480 V three-phase power, while the 6 mm² wire capacity accommodates the thick cables feeding high-power equipment like HVAC compressors and elevator motors.
Renewable energy systems
In a wind turbine’s control cabinet, the DYSF118B connects the generator’s output cables to the power converter. Its resistance to vibration (via torque-controlled screws) and high temperature tolerance ensure reliable operation in the turbine’s nacelle, where temperatures can reach 85°C during peak operation.

Commissioning: After installation, verify torque settings on all terminals using a calibrated torque screwdriver. Check continuity between connected devices using a multimeter to ensure proper wiring. Perform a high-voltage insulation test (up to 1000 V) to confirm insulation integrity between terminals and ground.
Maintenance: Inspect the module semi-annually for signs of overheating (discoloration) or loose connections. Re-tighten terminals to the specified torque if necessary. Clean dust and debris using a soft brush or compressed air. Replace the module if terminals show signs of corrosion, cracking, or excessive wear. In high-vibration environments, check torque quarterly to prevent loosening.
