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 240/415V; DC 24/48/130V Match the project control or supply circuit
Rating / operating window AC-12: 415V/3A or 240V/6A; DC-12: 130V/1A, 48V/2A or 24V/6A Use the published range; do not infer missing ratings
Interface for the CQB6 series 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

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-12: 415V/3A or 240V/6A; DC-12: 130V/1A, 48V/2A or 24V/6A with AC 240/415V; DC 24/48/130V. 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 designed specifically for the CQB6 series. 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.
