Product Overview

CQB3GQ-80 is a self resetting voltage protector for 230V or 230/400V AC applications. It is intended for single-phase or terminal-equipment circuits exposed to supply-voltage abnormalities; this describes an evaluation context, not a universal approval. Confirm the complete circuit design before specifying the product.

over/under-voltage disconnection with automatic reconnection 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.

Key Features

  • Published pole options: 1P+N, 2P or 4P as listed.
  • Published electrical context: 230V or 230/400V AC.
  • Primary function: over/under-voltage disconnection with automatic reconnection.
  • Selection reference: Thresholds and delay are model-specific; see the technical table.
  • Applicable standard reference: JB/T 12762 reference.
  • Final selection must use the exact model table, drawings and installation instructions.

Typical Applications

single-phase or terminal-equipment circuits exposed to supply-voltage abnormalities. Verify system voltage, expected fault current or leakage, wiring arrangement, environment, coordination and applicable rules for the ordered configuration.

CQB3GQ-80 Product FAQ

What is the CQB3GQ-80 used for?

The CQB3GQ-80 is specified for over/under-voltage disconnection with automatic reconnection in 230V or 230/400V AC applications, within the ratings and configurations listed in its technical table. Final suitability depends on the complete circuit design.

When does the CQB3GQ-80 reconnect after a voltage fault?

The reconnect delay is model-specific and is listed in the technical table. Confirm the documented threshold and delay, neutral arrangement and whether automatic reconnection is acceptable for the connected load.

How do I choose the CQB3GQ-80 rating and poles?

Start with the design current and system arrangement, then choose only a published option. The page lists pole options as 1P+N, 2P or 4P as listed; confirm neutral, polarity, conductors and isolation requirements.

What safety limitation applies to the CQB3GQ-80?

Do not treat the CQB3GQ-80 as a universal substitute for another device. Confirm Thresholds and delay are model-specific; see the technical table, the system voltage, fault or leakage conditions and any separate upstream protection before selection.

Can the CQB3GQ-80 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 CQB3GQ-80 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.

Confirm the Right CQB3GQ-80 Configuration

Send the model, rating, poles, system voltage, application, quantity and document requirements. CHAC will review the request against the published data.
