HSW2 series intelligent universal low-voltage circuit breakerDetailed product description：

Product Details

The HSW2 series intelligent universal low-voltage circuit breaker is an economical product. Suitable for distribution networks with AC frequency of 50 (60) Hz, rated working voltage up to 400V and below, and rated working current of 630A~4000A, used to distribute electrical energy and protect lines and power equipment from the hazards of overload, undervoltage, short circuit, single-phase grounding and other faults. Under normal conditions, it can also be used for infrequent switching of lines. The circuit breaker has intelligent protection function and four stage selective protection.
Intelligent, zero arc, with isolation, available in both pull-out and fixed types, with three or four poles, and can be installed with reverse wiring

It has overload long delay inverse time limit, short delay fixed time limit, and instantaneous functions. Users may set their own protective features required for composition
Single phase grounding protection function, display, overload alarm, overheat self-test, testing and other functions
Rated ultimate short-circuit breaking capacity Icu: 400V 50kA~80kA
Rated operating short-circuit breaking capacity Ics: 400V 40kA-60kA
Rated short-circuit withstand current Icw: 400V 40kA-60kA

The main differences between HSW1 and HSW2
1. The volume of HSW2 with the same current level is greater than HSW1
2. Short circuit breaking capacity HSW2 is lower than HSW1
3. The intelligent controller of HSW2 only has an L-type, while HSW1 has L, M, and H models to choose from
4. HSW2 cannot achieve automatic energy storage, while HSW1 can
5. HSW2 only has two shell levels of 2000 and 4000, while HSW1 has five levels of 1000, 2000, 3200, 4000, and 6300
6. HSW2 cannot come with a disconnect position key lock, while HSW1 can
