ABB S202UP-K10 10A 2-Pole 480 V Circuit Breaker Potential Transformer

The ABB S202UP-K10 10A 2-Pole 480 V Circuit Breaker Potential Transformer is a robust protection solution built for demanding 480-volt electrical distributions. Engineered by ABB, this part (S202UP-K10) delivers reliable overcurrent protection in a compact, two-pole package, making it an ideal choice for industrial panels, switchgear, and service entrances where precise control and dependable trip performance matter.

Overview

Designed to safeguard circuits operating at up to 480 V, the S202UP-K10 combines a 10 A current rating with a two-pole configuration. The result is a clear, dependable protection mechanism for feeders, motors, and critical loads in commercial and light industrial environments. This model’s integration with potential transformer-enabled protection and metering options helps align protection settings with monitoring systems, enabling better fault detection and coordination.

Key Specifications

• Current rating: 10 A
• Poles: 2
• Voltage rating: 480 V
• Part number: S202UP-K10
• Brand: ABB
• Function: Circuit protection for 480 V circuits with potential transformer compatibility

Use Cases & Ideal Applications

• Protect 480 V feeders and circuits in industrial panels, distribution boards, and switchgear assemblies.
• Pair with metering or protection relays that utilize potential transformer feedback for accurate fault and anomaly detection.
• Spacer or spare-part solution for ABB-based electrical systems where consistent performance and part traceability are important.
• Support preventative maintenance programs by providing a predictable, known-trim protection device within upgraded or legacy installations.

Why This Model Stands Out

• Brand assurance: ABB’s engineering heritage translates to reliable mechanical action, consistent trip characteristics, and long service life in demanding environments.
• Clear compatibility: The S202UP-K10 designation helps ensure seamless integration with ABB protection schemes and any monitoring setups that leverage potential transformer data for enhanced visibility.
• Targeted rating: A dedicated 10 A setting on a 480 V system provides precise protection for sensitive loads while avoiding nuisance trips in normal operation.

Installation, Care & Practical Tips

• Verify electrical compatibility with your 480 V distribution network and ensure proper alignment with the panel’s bus arrangement and enclosure clearances.
• Consult your system protection plan to coordinate the S202UP-K10 with associated relays and metering equipment that may use potential transformer feedback for accurate protection signaling.
• Follow standard electrical safety practices during installation, including proper torque on terminals and secure mounting to prevent vibration-related wear.
• Stock this ABB part as a reliable spare to minimize downtime in critical protection circuits and to support consistent maintenance routines.

Who Should Consider This Product

• Electrical engineers and panel builders designing or upgrading 480 V industrial power feeds.
• Maintenance professionals seeking dependable, traceable ABB components for service continuity.
• Facility managers and procurement teams aiming for standardized parts in ABB-based protection architectures.
