ABB 1SVR011718R2500 DIN Rail-Mounted Terminal Block (Single-Pole)

Description

1SVR011718R2500

The ABB 1SVR011718R2500 functions as a single-pole, screw-terminal block designed for DIN rail mounting (35mm, per EN 60715), serving as the backbone of organized wiring in control panels and electrical enclosures. Unlike basic terminal blocks, it uses a cage-clamp termination system that securely grips both solid and stranded wires (without requiring ferrules for stranded types), ensuring consistent contact pressure even in high-vibration environments—critical for preventing loose connections that cause intermittent faults.

When a wire is inserted and the screw is tightened, the cage clamp closes around the conductor, creating a gas-tight seal that resists corrosion and oxidation, extending the life of the connection. The terminal block supports a wide range of wire gauges (0.5mm² to 4mm² / 20AWG to 12AWG), making it suitable for both power circuits (e.g., 24V DC control power) and signal circuits (e.g., analog sensor signals). By mounting directly onto standard DIN rails, it integrates seamlessly with other panel components (like contactors, relays, or PLC modules), creating a neat, modular wiring layout. In the electrical system stack, the ABB 1SVR011718R2500 sits between field devices (sensors, actuators) and control equipment, acting as a reliable junction point that simplifies wiring management—ensuring technicians can quickly trace, modify, or repair circuits without disrupting the entire system.

Main features and advantages:

Choosing the ABB 1SVR011718R2500 delivers tangible value that streamlines wiring, reduces maintenance costs, and enhances system reliability. Engineered for industrial ruggedness, its housing is made from flame-retardant polyamide 6.6 (UL 94 V-0 rated), which withstands extreme temperatures, chemical exposure, and mechanical impact—ensuring performance in harsh environments like oil refineries, automotive plants, or outdoor renewable energy installations. This durability translates to a service life of 15+ years, compared to 5–8 years for low-grade terminal blocks, minimizing replacement cycles and long-term costs. For electricians, the cage-clamp termination system cuts installation time by 30%: it eliminates the need for ferrules (for stranded wire) and allows tool-free wire insertion (with standard screwdrivers), reducing wiring errors and fatigue during large-panel assemblies.

Additionally, the ABB 1SVR011718R2500’s narrow width (6.2mm) maximizes space efficiency in control panels—critical for modern, compact automation systems where every millimeter counts. Its gray color coding (consistent with ABB’s wiring accessory lineup) simplifies circuit identification, making troubleshooting faster: technicians can quickly distinguish power circuits from signal circuits by color, reducing diagnostic time during downtime. Unlike terminal blocks with weak contact pressure, the cage-clamp design maintains a secure grip even during vibration (common in motor control panels or mobile equipment), preventing arcing and overheating that can damage wires or equipment. This compliance with IEC 60947-7-1 also ensures the terminal block meets global safety standards, reducing the risk of electrical hazards and compliance violations.

Application fields:

The ABB 1SVR011718R2500 excels in industries where organized, reliable wiring is mission-critical. In renewable energy (wind and solar), it’s used to terminate sensor and control wires in inverter cabinets: its wide temperature range (-40°C to 120°C) withstands extreme outdoor conditions, and vibration resistance ensures connections remain secure in wind turbine nacelles. In automotive manufacturing, it’s a staple in robot control panels—its compact design fits into space-constrained enclosures, and compatibility with both power and signal wires simplifies wiring for robotic arms and conveyor systems. In commercial buildings, it’s used in HVAC control panels: the cage-clamp termination securely connects thermostat wires and fan motor controls, preventing loose connections that cause heating or cooling system failures. Across all these use cases, the ABB 1SVR011718R2500’s versatility and reliability make it a foundational component for safe, efficient electrical systems.

Installation and maintenance:

Before installing the ABB 1SVR011718R2500, confirm the DIN rail is compatible (35mm, EN 60715) and securely mounted to the panel—loose rails can cause terminal blocks to shift, disrupting connections. Ensure the panel is de-energized and locked out/tagged out (LOTO) to prevent electrical shock; strip wire insulation to the correct length (8mm–10mm, per ABB specs) to avoid exposed conductors or incomplete insertion. For stranded wire, no ferrule is needed, but ensure all strands are fully inserted into the cage clamp—strands left outside can cause short circuits. Tighten the terminal screw to 0.8–1.2 Nm (using a torque screwdriver for consistency); over-tightening can damage the cage clamp, while under-tightening reduces contact pressure. When mounting multiple terminal blocks, align them evenly on the DIN rail to maintain a neat layout—use ABB’s DIN rail end stops to prevent shifting during panel transport.

For ongoing maintenance, inspect terminals quarterly for loose screws (especially in high-vibration areas) and corrosion (in humid environments); retighten screws as needed and clean corrosion with a dry brush. Test connections annually using a multimeter to verify continuity—intermittent continuity indicates a loose or damaged terminal.
