What does the 32A rating mean?

The 32A rating indicates the breaker's maximum continuous current capacity. It will trip (disconnect) automatically if current exceeds this threshold for an extended period.

Is this suitable for household use?

Yes, the QHB320 is commonly used in residential electrical installations for protecting circuits supplying lights, outlets, and other household loads.

What is the 250V specification?

The 250V AC rating indicates the maximum voltage the breaker is designed to safely operate with. This is suitable for single-phase household and light commercial circuits.

What is the breaking capacity of 6kA?

Breaking capacity is the maximum fault current the breaker can safely interrupt. A 6kA capacity means it can handle short-circuit currents up to 6,000 amperes before failing.

Does it fit standard DIN rail enclosures?

Yes, the QHB320 is designed for standard DIN rail installation, commonly found in distribution boards and electrical panels. It occupies one module width (18mm).

What is the difference between Type B and other trip classes?

Type B breakers trip at 3-5 times rated current. This makes them suitable for circuits with minimal inrush current, such as residential lighting and outlet circuits.

Is this product still available?

Yes, the QHB320 is an active product in Schneider Electric's catalog and remains widely available through distributors and retailers.
