LV Molded Case CB (MCCB)
The HS1 series low voltage molded circuit breaker is designed to operate
on 50/60Hz AC, with a rated insulation voltage of 1000V, operating voltage
AC400V/230V, and current capacity from 20a to 600A. The breaker provides
reliable protection for electrical power distribution and protection of engines. The
HS1E is also intended for use in measuring boxes since it can interact with the meter
and receive commands, such as query and control. Therefore, the HS1M is a generic
version for multiple uses.
Key Features
- The breaker is used for infrequent circuit switching and starting of motors, with protection from overload, electrical shorting, and insulation.
- It is equipped with a key lock (anti-lock) and end cap at the entry and exit points, which enhances safety and achieves an IP30 protection rating.
- Reference temperature of up to 55°C with withstand voltage shocks of up to 8kV and easy wiring options.
- Thermo-magnetic design with high cutting capacity and advanced features, such as:
- Easily adjustable interior accessories.
- AD Arc Drive technology to prevent electrical sparks.
- A uniform size for 630A and 400A circuit breakers
- Increase cutting capacity per unit volume.
- Raise insulation voltage to Ui=1000V.
