Product Introduction
The DZ20Y-225/33002 180A molded case circuit breaker is designed for power distribution networks with AC 380V/50Hz or lower voltage systems. Featuring a durable thermoplastic housing, this device provides reliable protection against overload and short-circuit conditions in three-phase systems. With 180A current rating and 225A frame size, it suits medium-capacity power distribution applications including motor protection circuits. The compact design incorporates visible operation indicators and supports both front/rear wiring configurations for flexible installation.117
Key Features
This breaker employs advanced thermal-magnetic trip technology with adjustable settings, achieving ±20% accuracy in instantaneous trip calibration. The 180A variant demonstrates excellent interrupting capacity, while the 200mm arc distance ensures safe operation. Optional motorized operation mechanism allows remote control within 85-110% rated voltage range. The built-in shunt trip (70-110% operable range) and undervoltage release (35-70% cutoff) provide additional protection layers. Silver-alloy contacts ensure low resistance and extended service life exceeding 10,000 mechanical operations. Transparent cover version enables visual contact status inspection without disassembly.619
Typical Applications
Ideal for commercial buildings, industrial plants and infrastructure projects requiring 160-200A circuit protection. Frequently installed in main distribution panels, motor control centers and sub-feeder circuits. Suitable for occasional switching of power lines and motor starting protection in ambient temperatures from -5°C to +40°C. The IP20 enclosure protects against dust ingress while permitting vertical or horizontal mounting orientations. Optional extended handles facilitate operation in confined spaces. Not recommended for explosive atmospheres or high-vibration environments.59
