Molded Case Leakage Protection Circuit Breaker DZ20L-250T/4300
Product Overview
The DZ20L-250T/4300 molded case leakage protection circuit breaker is an intelligent protection device designed for low-voltage distribution systems. With a rated current of 250A and earth leakage tripping threshold of 30mA, it achieves instantaneous tripping within 0.1 seconds through rapid response technology. The transparent housing allows visual inspection of internal components, suitable for industrial, commercial and residential electrical safety applications.
Key Features
-
Precision Leakage Protection
Integrated high-sensitivity electronic detection module continuously monitors leakage current. Triggers power cutoff within 0.1 seconds when leakage reaches 30mA threshold, effectively preventing electrical hazards.
-
Enhanced Structural Design
• Multi-stage arc chute system improves breaking capacity
• Transparent flame-retardant housing combines visibility and durability
• Modular contact system simplifies maintenance
-
User-Friendly Operation
• Triple-position mechanical indicator shows ON/OFF/TRIP status
• Test button enables periodic function verification
• Wide temperature tolerance (-25℃~+60℃) ensures stable performance
Application Guidance
Ideal for main distribution panel switches, equipment power control units, and temporary power systems. Provides reliable protection for construction sites, manufacturing facilities, and commercial complexes. Recommended to activate test button quarterly for operational confirmation.
