Protetor de Sobre-Subtensão de Reparo Automático da Série CQB3GQ-80
O CQB3GQ-80 is specified for over/under-voltage disconnection with automatic reconnection. Select it using the published voltage, current, pole and protection data, then confirm conductor coordination, fault conditions, enclosure requirements and local installation rules.
Visão Geral do Produto
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.

Voltage Protection and Reconnection
Over/under-voltage devices disconnect when thresholds are reached and may reconnect after a delay. Confirm thresholds, delay, neutral arrangement and downstream load behaviour.

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.
