Molded Case Leakage Protection Circuit Breaker DZ20L-250T/4300
225A/150mA/0.2S Delay Time with Transparent Housing
Product Overview
The DZ20L-250T/4300 is a molded case leakage protection circuit breaker featuring a transparent housing design. With a rated current of 225A, leakage tripping threshold of 150mA, and delay time of 0.2 seconds, it integrates overload, short-circuit, and leakage protection functions to deliver comprehensive safety for low-voltage distribution systems. The transparent housing allows visual monitoring of internal operations, making it suitable for industrial, commercial, and residential applications.
Key Features
-
Multi-Layer Protection
Simultaneously detects overload, short-circuit, and leakage faults. The 0.2-second delay mechanism intelligently identifies persistent abnormal currents to achieve precise tripping while minimizing false operations.
-
Visual Monitoring
High-transparency engineering plastic housing provides clear visibility of contact status and arc extinguishing processes, enabling efficient fault diagnosis and maintenance.
-
High Breaking Capacity
Optimized arc chute structure rapidly suppresses fault arcs, with breaking capacity meeting standard distribution load requirements to protect downstream equipment.
-
Modular Construction
Plug-in terminals and standardized modules support quick installation and replacement, compatible with mainstream distribution cabinet mounting rails.
Applications
- Main/branch circuit protection in building power systems
- Leakage protection for production equipment supply lines
- Safety isolation in temporary power supply scenarios
- Power distribution safety in medical/educational facilities
