What does this carriage switch do in a drawout circuit breaker installation?

It provides an auxiliary indication signal when the breaker carriage is in the chassis test position (CT). This allows control circuits, PLC inputs, or panel indicators to monitor the mechanical position of the drawout device.

Which breaker ranges is this switch designed to work with?

It is designed for Schneider Electric drawout systems including MasterPact NT, MasterPact NW (including NW DC), and ComPacT NS630b to NS1600 drawout applications.

What is meant by the chassis test position (CT)?

The chassis test position is a defined mechanical position of a drawout breaker where position signalling is available via the carriage switch. It is used for position monitoring and control logic based on the drawout status.

What contact configuration does the switch provide?

It provides one changeover contact (1 NO/1 NC), enabling either normally-open or normally-closed signalling depending on how you wire the control circuit.

Is this intended for monitoring or for switching power loads?

It is intended for monitoring and signalling (auxiliary circuit use). It is rated under utilisation categories such as AC-12 and DC-12, which are typical for control and indication circuits rather than power switching.

What are the key electrical ratings for typical control voltages?

Typical ratings include AC-12 up to 8 A at 240/380/480 V AC (and 6 A at 690 V AC), and DC-12 ratings such as 2.5 A at 24/48 V DC and 0.8 A at 125 V DC. These values help size the signalling circuit and protective devices appropriately.

Is there a minimum load requirement for reliable operation?

Yes. The minimum load is 100 mA at 24 V, which is useful to consider when driving very low-power inputs to ensure dependable contact performance.

Where is the switch mounted in the system?

It is a drawout-mounted auxiliary contact used as a carriage switch for the chassis, actuated by the mechanical movement of the breaker within the drawout mechanism.

Can it be used to distinguish between different drawout positions?

It is specifically associated with the test position (CT). If you need separate signalling for other positions (for example, connected or disconnected), that typically requires additional dedicated position contacts.

Does it meet common environmental compliance expectations for EU installations?

It is declared REACh compliant (including being free of SVHC as declared) and is aligned with EU RoHS expectations as stated for the product family, supporting common compliance needs for panel builds in the UK and EU.

Are there any regulatory chemical disclosures that may be relevant for exports?

The product information includes a California Proposition 65 chemical warning disclosure. This may be relevant when preparing documentation for exports where such declarations are requested.

How is this item commonly referenced in control schematics?

It is commonly shown as a position-operated auxiliary contact associated with the breaker carriage test position, using a changeover contact symbol (NO/NC) and labelled to indicate CT or test-position status. In documentation it may be referenced by its Schneider designation, such as 33752, in the bill of materials.
