PXB6-SD Alarm Contact
The PXB6-SD alarm contact is specified for alarm contact for fault-trip indication. Published data includes AC 230V / DC 110V and AC-15 230V 6A; DC-13 110V 1A. Confirm the accessory interface, control circuit, wiring and destination-market requirements before ordering.
Product Overview
PXB6-SD is a alarm contact for low-voltage panel and breaker accessory systems. The summary below uses the published model record; it does not replace the complete drawing, wiring instructions or project design review.
Alarm contact for fault-trip indication. AC-15 230V 6A; DC-13 110V 1A is the published electrical reference. Compatibility, contact logic and installation details must be confirmed for the exact ordered version.
Key Features
Typical Applications
Use it where a breaker fault trip must be reported to a panel, PLC, BMS or audible signaling circuit. An alarm contact should not be described as a normal auxiliary status contact; confirm the target breaker's accessory interface and the project's alarm logic.
Applications and Selection Guide
Use the product-specific values below as a shortlist, then validate the complete circuit and mechanical interface. An accessory rating alone does not establish compatibility with every breaker, panel or control system.
| Selection point | PXB6-SD reference | What the project must confirm |
|---|---|---|
| Primary function | alarm contact for fault-trip indication | Confirm the required signal or protection function before ordering |
| Electrical reference | AC 230V / DC 110V | Match the project control or supply circuit |
| Rating / operating window | AC-15 230V 6A; DC-13 110V 1A | Use the published range; do not infer missing ratings |
| Interface | for compatible PXB6 breaker accessory interface | Verify the compatible breaker, panel, base or rail interface |
| Wiring | 0.5–2.5mm² conductor reference | Final conductor and protection selection follows the project design and local rules |
| Documents | IEC 60947-5-1 | Request the exact drawing and applicable compliance documents for the ordered version |
Function and signal path
Alarm contact for fault-trip indication. Confirm whether the circuit needs status feedback, fault alarm, remote trip or voltage release.
Control-circuit fit
AC 230V / DC 110V. Match the control voltage and operating window to the project circuit; never assume a nearby rating is interchangeable.
Mechanical interface
for compatible PXB6 breaker accessory interface. Confirm breaker family, rail/base or panel interface, clearances and maintenance access.
Wiring and documentation
0.5–2.5mm² conductor reference. Request the exact drawing and installation document for the ordered configuration.
Ordering Guide
- Specify the exact model and accessory function: PXB6-SD, alarm contact for fault-trip indication.
- State the control/supply voltage and any required operating window.
- Confirm the compatible breaker family, panel, base or DIN-rail interface.
- Provide quantity, destination market, wiring details and required technical documents.
- Ask CHAC to verify any non-standard marking, packaging or configuration request before production.
Installation and Coordination Checks
- Use the exact product drawing and installation instructions for the ordered configuration.
- Verify voltage, conductor, terminal, enclosure, clearances and maintenance access.
- Check the accessory’s signal or trip logic against the control circuit and upstream/downstream protection.
- Installation, testing and maintenance must be carried out by qualified personnel under applicable rules.

PXB6-SD Product FAQ
What does the PXB6-SD indicate?
The PXB6-SD is intended to signal a breaker fault trip. It should be evaluated as an alarm contact, not assumed to follow every normal manual open/close operation.
What is the difference between an alarm contact and an auxiliary contact?
An alarm contact is used to report a fault-trip condition, while an auxiliary contact normally reports the breaker's open/closed status. The exact contact logic must be verified from the product drawing.
What ratings are published for the PXB6-SD?
The published ratings are AC-15 230V 6A; DC-13 110V 1A with AC 230V / DC 110V. Confirm the connected PLC, indicator or audible alarm circuit is within those values.
Can the PXB6-SD drive an audible alarm directly?
It can be part of an alarm circuit, but the complete circuit must be checked for voltage, current, isolation and any relay or interface required by the project.
Which breaker is the PXB6-SD compatible with?
The PXB6-SD is described as a modular accessory for a compatible breaker family. Confirm exact breaker model and interface before ordering.
How should the PXB6-SD be tested?
Use the approved product instructions and a controlled fault-simulation or functional test method suitable for the installed system. Testing must be performed by qualified personnel.
