Product Introduction
The DZ20L-160T/4300 molded case leakage protection circuit breaker is a safety device designed for power distribution networks, suitable for 50Hz AC power systems with rated voltage up to 380V. Featuring a transparent housing for visual inspection, it has a rated current of 160A and residual operating current of 200mA. With non-delay protection characteristics (operating time ≤0.1s), it effectively prevents electric shock and equipment leakage risks. The front-wiring design ensures easy installation, making it suitable for various applications including industrial, commercial and residential scenarios.415
Key Features
This circuit breaker adopts high-quality engineering plastic housing with excellent insulation and mechanical strength. The transparent case allows users to visually inspect internal contacts and arc extinguishing chamber. Equipped with compound trip mechanism, it provides both overload and short-circuit protection. The specially designed arc extinguishing system quickly quenches fault arcs with breaking capacity up to 12kA. The terminal-less design simplifies installation process and saves construction time.38
Technical Specifications
Main technical parameters include: rated operational voltage 380V, rated current 160A, 3P+N poles (N pole remains connected independently). Residual operating current 200mA with response time ≤0.1s, mechanical endurance over 50,000 operations. Compact dimensions support both DIN rail mounting and bolt fixing, suitable for various distribution box requirements. Operating temperature range covers from -5℃ to +40℃, ideal for most indoor applications.519
Application Scenarios
Widely used in building power distribution, industrial control, commercial lighting and other scenarios requiring leakage protection. Particularly suitable as main switch in distribution boxes, motor protection, and cable line protection. The transparent design makes it ideal for locations requiring frequent inspection like schools and hospitals. It effectively prevents electrical accidents and fire risks caused by insulation failure, providing reliable power safety.17
