FAQs

 

What are the main functions of the DZ158 MCCB?

It provides overload and short-circuit protection, along with switching and isolation functions in low-voltage distribution systems.

 

What voltage and current ranges does it support?

The DZ158 supports 230/400 ~ 240/415 V AC and 60/110 ~ 110/220 V DC, with rated currents from 63 A to 125 A.

 

What makes the DZ158 suitable for industrial and commercial use?

It features high breaking capacities (6 kA / 10 kA), IP20 protection, and strong mechanical endurance (up to 8,500 operations), making it durable under frequent load switching.

 

How does ambient temperature affect performance?

The breaker’s rated current is based on a 30 °C reference. For higher ambient temperatures, derating applies—for example, at 60 °C, only ≈ 86% of rated current can be maintained.

 

Can the DZ158 be combined with accessories?

Yes. The MCCB is compatible with auxiliary contacts and other CHINT accessories for status indication and system integration.
