Product description
SV Circuit-breaker component adaptor, 125 A, 690 V, 3-pole, cable outlet top, round conductor connection 35-120 mm², clamping area WH: 18,5x15,5 mm
Feature: 3-pole adaptor rated 125 A at 690 V enables common high-current circuit-breaker integration. Business Impact: Supports reliable protection schemes for feeders and distribution feeders, reducing the need for custom parts and accelerating panel readiness. Application: Use in switchgear where ABB S1/S2 or T-series breakers are deployed, ensuring a snug fit with standard 60 mm busbar spacing. Feature: Top cable outlet simplifies front-entry wiring and reduces enclosure depth. Business Impact: Improves cable management, minimizes derating risks, and speeds installation. Application: Ideal for front-entry wiring in compact switchgear housings. Feature: Round conductor connections for 35–120 mm² conductors provide flexible, robust terminations. Business Impact: Maintains low contact resistance and enables broader conductor selection. Application: Suitable for power distribution blocks in industrial control panels. Feature: Clamping area for laminated copper bars (18.5 x 15.5 mm) optimizes conductor securing. Business Impact: Enhances electrical contact quality, reduces movement under vibration, and supports longer service life. Application: Best for laminated copper busbar interfaces in modular assemblies. Feature: Polyamide construction with fire protection (UL 94-V0) delivers improved safety in enclosures. Business Impact: Supports regulatory compliance and reduces risk of enclosure-wide ignition. Application: Particularly beneficial in metal or composite enclosures with strict fire-safety requirements. Feature: ABB compatibility noted for model range (S1, S2, T1, T1 UL, T2, T2 UL, XT1, XT2). Business Impact: Accelerates procurement and reduces engineering time by ensuring drop-in compatibility. Application: Useful in mixed-brand switchgear environments where ABB components are present.

FAQs
Begin by verifying busbar spacing of 60 mm and the top cable outlet orientation. Mount the adaptor onto the circuit-breaker frame, align the 3-pole terminals, and insert round conductors in the 35–120 mm² range. Tighten clamps to the recommended torque, attach terminal cover, and route cables through the top outlet for clean enclosure integration. This process reduces assembly time and ensures a secure, vibration-resistant connection.
The adaptor is rated for 125 A with a rated operating voltage of 690 V, 3-phase. Its UL (SCCR) rating is 65 kA at 480 V, supporting robust short-circuit capability for demanding switchgear. It uses a top cable outlet and is designed for round conductors from 35 to 120 mm², with a clamp area sized for laminated copper bars 18.5 x 15.5 mm.
Yes, the adaptor material is UL 94-V0 rated, indicating high flame resistance and enhanced safety in enclosure environments. This compliance helps reduce risk in electrical cabinets and aligns with common industrial safety standards, supporting safer maintenance and firefighting performance in the event of an arc or fault.
Compatibility covers ABB S1, S2, T1, T1 UL, T2, T2 UL, XT1, and XT2 series. This broad compatibility simplifies part selection in mixed-brand installations and reduces the need for multiple adaptor variants when upgrading or retrofitting switchgear.
Key ROI drivers include faster assembly due to a universal 3-pole design, reduced spare-parts inventory by using a single adaptor across ABB models, and improved safety with UL 94-V0 material. The top-cable outlet and 60 mm busbar spacing streamline wiring and alignment, lowering commissioning time and post-installation rework.
