Product Overview

The S800-AUX/ALT is a compact accessory that easily attaches to the side of an S800 series HPCB (such as S800S, S800N, S800C, S800B, etc.). Its primary function is to provide remote indication of the circuit breaker’s state, enhancing monitoring and control capabilities within an electrical system.

It features two distinct contact types:

• AUX (Auxiliary) Contact: This contact always switches simultaneously with the main contacts of the circuit breaker, indicating its on/off state, as well as tripping due to thermal overload or magnetic (short-circuit) overload, or manual tripping.
• ALT (Alarm/Trip) Signal Contact: This contact specifically signals a trip condition of the circuit breaker, whether due to thermal overload, magnetic overload, or tripping initiated by an undervoltage release (S800-UVR) or shunt opening release (S800-SOR). The ALT contact can be reset independently using a reset button on the unit.

Product Parameters (Key Features & Specifications)

While detailed specifications can vary slightly based on the exact part number, here are general parameters for the S800-AUX/ALT:

• Compatibility: Designed for use with ABB S800 series High Performance Circuit Breakers (e.g., S800S, S800N, S800C, S800B, S800HV, S800U, S800PV-SP, S800PV-SD, S800PV-M-H).
• Contact Configuration:
  • AUX: Typically a changeover contact (1 NO + 1 NC or similar arrangement).
  • ALT: Typically a changeover contact (1 NO + 1 NC or similar arrangement).
• Rated Insulation Voltage (Ui​): Up to 690 V AC (IEC standards).
• Rated Operating Current (Ie​): Varies by utilization category (e.g., AC-15, DC-13). For instance:
  • AC-15: 6 A at 240 V AC, 2 A at 400 V AC.
  • DC-13: 4 A at 24 V DC, 0.55 A at 250 V DC.
• Conventional Free Air Thermal Current (Ith​): Typically 6 A.
• Minimum Operational Current (Imin​): Typically 3 mA.
• Minimum Operational Voltage (Umin​): Typically 24 V.
• Mounting: DIN rail mountable, side-mounted onto the S800 HPCB.
• Standards: Compliant with standards like IEC 60947-5-1, UL 489.
• Dimensions: Compact design, typically around 95 mm (height) x 9 mm (width) x 65 mm (depth, including HPCB).
• Weight: Approximately 53 grams.

Product Advantages

• Enhanced Monitoring: Provides clear and immediate remote indication of the circuit breaker’s status (ON/OFF, tripped).
• Improved Fault Diagnostics: The separate ALT contact specifically indicates a trip condition (thermal, magnetic, or auxiliary trip), helping operators quickly identify the cause of an outage.
• Increased Safety: Allows for remote monitoring of critical circuit breaker states, reducing the need for personnel to be in close proximity to energized equipment.
• Seamless Integration: Designed to perfectly fit and integrate with the ABB S800 series HPCBs, ensuring reliable operation and straightforward installation.
• Versatility: Compatible with a wide range of S800 models, making it a flexible solution for various applications.
• Ease of Installation: Simple DIN-rail mounting and direct attachment to the HPCB minimize installation time and effort.
• Compact Design: Adds minimal footprint to the overall circuit breaker assembly.

Precautions

• Compatibility: Ensure the S800-AUX/ALT is compatible with your specific S800 series HPCB model. Always refer to the ABB product documentation.
• Wiring: Follow the wiring diagrams and instructions provided by ABB precisely. Incorrect wiring can lead to malfunction or damage.
• Safety: Always de-energize the circuit breaker and follow all lockout/tagout procedures before installing or removing the S800-AUX/ALT.
• Environmental Conditions: Install the unit within the specified environmental conditions (temperature, humidity, etc.) to ensure reliable operation and longevity.
• Test Function: Utilize the integrated test button (operated by a tool) to simulate the function of the auxiliary contact without tripping the main circuit breaker. This is useful for commissioning and troubleshooting.
• Reset Function: Understand that the ALT signal contact has a reset button. This allows the alarm signal to be cleared after a trip, independent of the main circuit breaker’s state.

Product Applications

The ABB S800-AUX/ALT is widely used in various electrical distribution applications where remote signaling of circuit breaker status is essential:

• Industrial Automation: Integrating circuit breaker status into industrial control systems (PLCs, SCADA) for centralized monitoring and control.
• Building Automation Systems: Providing real-time information on electrical circuit status in commercial and residential buildings.
• Power Distribution Boards and Switchboards: Enabling remote indication of circuit breaker operation for maintenance and operational staff.
• Motor Control Centers (MCCs): Signaling the status of circuit breakers protecting motor loads.
• Critical Infrastructure: Used in data centers, hospitals, and other facilities where immediate notification of electrical faults is crucial for system reliability and uptime.
• Remote Monitoring: Facilitating remote diagnostics and troubleshooting by providing clear indications of tripping events and circuit breaker positions.
