CQB58 Product FAQ

What is a two-pole circuit breaker?

A two-pole device operates two conductors together. CQB58 has a fixed 2P1E arrangement, so the buyer must confirm exactly which conductor is protected and how both conductors are switched in the intended system.

Does 2P1E mean the same as a standard double-pole MCB?

Not automatically. 2P1E identifies the published pole-and-element arrangement of CQB58. Do not assume identical protection in both poles without confirming the product diagram and application requirements.

What does kA mean on a circuit breaker?

kA normally describes short-circuit interrupting capacity, but CQB58 currently publishes a 1.5kA rated short-time-current value. That wording must not be re-labelled as a verified high breaking-capacity claim.

Would a higher kA rating make CQB58 a better choice?

A higher verified interrupting rating can suit a higher prospective fault level, but selection still depends on the complete system. For CQB58, use the exact published short-time-current data and confirm suitability with the project designer.

Will a breaker trip as soon as it reaches its rated current?

Not necessarily. CQB58 uses a thermal overload trip, so response depends on overcurrent magnitude, duration and reference conditions. The rated current should not be interpreted as an instantaneous-trip threshold.

How do I choose the correct CQB58 safety breaker?

Confirm 230V AC suitability, the fixed 2P1E arrangement, the required 10A–40A rating, fault level, top connection, conductor limit, enclosure and applicable installation rules before ordering.

Confirm the Right CQB58 Configuration

Send your current rating, pole arrangement, trip option, system voltage, prospective fault level, destination market and quantity. CHAC will review the request against the published product range.
