CQD2-125 Series Miniature Isolating Switches for Control Circuits
Der CQD2-125 is specified for safe electrical isolation and infrequent switching. Select it using the published voltage, current, pole and protection data, then confirm conductor coordination, fault conditions, enclosure requirements and local installation rules.
Produktübersicht
CQD2-125 is a miniature isolating switch for AC 230/400V applications. It is intended for control and terminal distribution assemblies requiring a visible OFF position; this describes an evaluation context, not a universal approval. Confirm the complete circuit design before specifying the product.
safe electrical isolation and infrequent switching is distinct from adjacent protection functions. Do not infer AC/DC suitability, residual-current protection, automatic control or isolation performance from the product family name alone.

Isolation vs Overcurrent Protection
An isolating switch provides a means of disconnection but is not automatically an overcurrent protective device. Coordinate it with the upstream breaker.

CQD2-125 Product FAQ
What is the CQD2-125 used for?
The CQD2-125 is specified for safe electrical isolation and infrequent switching in AC 230/400V applications, within the ratings and configurations listed in its technical table. Final suitability depends on the complete circuit design.
Does the CQD2-125 provide overload protection?
No overcurrent claim is added for this isolating switch. It provides the documented isolation and switching function; coordinate it with the appropriate upstream protective device.
How do I choose the CQD2-125 rating and poles?
Start with the design current and system arrangement, then choose only a published option. The page lists pole options as 1P / 2P / 3P / 4P; confirm neutral, polarity, conductors and isolation requirements.
What safety limitation applies to the CQD2-125?
Do not treat the CQD2-125 as a universal substitute for another device. Confirm Isolation function; not an overcurrent substitute, the system voltage, fault or leakage conditions and any separate upstream protection before selection.
Can the CQD2-125 be used in another circuit type?
Only when the exact ordered configuration is rated for that circuit. AC and DC duties, residual-current devices, isolators, smart controls and voltage protectors are not interchangeable by appearance or current rating.
How should the CQD2-125 be installed and tested?
Use the exact product drawing, terminal identification and instructions. A qualified person should verify isolation, conductors, torque, settings, coordination and functional tests before energising the circuit.
