CHANGSHU INTELLIGENT CM5Z-1600L ELECTRIC MOLDED CASE CIRCUIT BREAKER

CHANGSHU INTELLIGENT CM5Z-1600L ELECTRIC MOLDED CASE CIRCUIT BREAKER is a large-frame intelligent MCCB (Moulded Case Circuit Breaker) from Changshu Switchgear CM5Z series, rated 1600A frame with L-class short-circuit breaking capacity, equipped with electronic trip unit and optional motor operating mechanism for low-voltage power distribution protection. The molded case circuit breaker provides multi-stage adjustable protection curves including long-time overload, short-time delay, instantaneous short-circuit and earth fault protection for main power feeders and heavy industrial load circuits. The molded case circuit breaker supports built-in power metering functions for voltage, current, active power, energy and harmonic measurement, with historical fault event recording for power system analysis. The molded case circuit breaker offers optional communication interface for remote status feedback, parameter setting and control via SCADA and power management systems. The molded case circuit breaker can be configured with auxiliary contacts, alarm switches and motor operator for local and remote closing / tripping operation.

CHANGSHU CM5Z-1600L adopts compact molded housing with advanced arc extinguishing technology for cabinet mounting. The intelligent power breaker holds IEC 60947-2 and GB/T14048.2 compliance for industrial and marine low voltage power networks. The intelligent power breaker supports fixed and drawout installation options for convenient maintenance. The intelligent power breaker has configurable protection delay timers to avoid false tripping caused by transient power surges. The intelligent power breaker features trip unit self-diagnosis to continuously monitor electronic module health status. The intelligent power breaker can resist electrical noise interference and temperature fluctuation in harsh industrial environments.

CHANGSHU INTELLIGENT CM5Z-1600L is widely applied in marine switchboards, industrial plants, commercial buildings and power station low-voltage main distribution systems. The industrial spare part can replace defective circuit breakers to restore multi-function power protection and power data metering rapidly. The industrial spare part matches original mechanical and electrical specifications for direct cabinet installation replacement. The industrial spare part has clear part marking for fast identification and stock management. The industrial spare part reduces power system downtime during power distribution cabinet overhaul and system upgrade.
