With a focus on safety and reliability, this breaker combines a modular design with intelligent trip units, enabling precise protection in industrial and commercial applications. Its compact footprint and easy maintenance features make it suitable for space-constrained switchgear installations.
High Breaking Capacity: Capable of interrupting short-circuit currents up to 100kA (400V AC), ensuring safe operation in high-fault environments.
Microprocessor-Based Trip Unit: Offers adjustable protection settings for overload, short circuit, ground fault, and undervoltage, with self-diagnostic functions.
Arc Suppression Technology: Integral arc chutes and magnetic blowout coils minimize arcing, extending contact life and reducing maintenance needs.
Modular Design: Removable control units and interchangeable accessories allow quick replacement and system upgrades without downtime.
IP54 Protection: Dust-tight and protected against water splashes, suitable for harsh industrial environments.
The DW45 is primarily used in:
Power Substations: Protects transformers, generators, and feeder circuits in medium-voltage distribution systems.
Industrial Plants: Installed in motor control centers and switchboards to safeguard large electrical loads in steel mills, refineries, and chemical plants.
Commercial Buildings: Used in high-rise complexes and data centers for reliable power distribution and emergency backup systems.
Renewable Energy Grids: Controls power flow in solar and wind farms, ensuring grid stability during transient fault events.
Q: What voltage ratings are available for the DW45?
A: It supports AC voltages from 400V to 690V, with specific models available for 3-phase or single-phase systems.
Q: Can the trip unit be configured remotely?
A: Yes, optional wireless modules enable remote setting adjustments and fault monitoring via a dedicated control software.
Q: How often should the breaker be serviced?
A: Routine maintenance is recommended every 3-5 years or after 1,000 operations, depending on the severity of the operating environment.
Q: Is there a version with a built-in isolation switch?
A: Yes, combined breaker-isolator models are available for applications requiring a visible break in the circuit for safety maintenance.
