Specifications General Product Type: Miniature Circuit Breaker (MCB) Model: EZ7 Configuration: 4P (Four-pole) Rated Current (In): 32A Mounting: DIN rail Application: Overload and short-circuit protection for three-phase electrical circuits, including both phase and neutral conductors Electrical Ratings Rated Operational Voltage (Ue): 400V AC (three-phase) Rated Insulation Voltage (Ui): 690V AC Rated Impulse Withstand Voltage (Uimp): 6kV Short-Circuit Withstand Capacity (Icu): 6kA Rated Frequency: 50/60Hz Protection & Trip Characteristics Thermal Overload Protection: Provides thermal protection for the circuit by tripping the breaker when the current exceeds the rated value for a certain time. Short-Circuit Protection: The magnetic trip mechanism ensures instantaneous tripping when a short-circuit occurs, preventing potential damage to the circuit. Trip Characteristics: Features a D-curve, which is commonly used for circuits with high inrush currents such as motors or transformers. Adjustable Settings: Some models may allow for adjustment of the overload protection and short-circuit protection settings. Mechanical & Environmental Degree of Protection: IP20 (for the front face) Housing: Compact, modular design for easy integration into electrical panels Cable Connections: Screw terminals for secure connections Mechanical Durability: Rated for 10,000 operating cycles Operating Temperature Range: -5°C to +40°C Humidity: Suitable for standard indoor environments Pollution Degree: Suitable for use in general industrial and commercial environments Accessories & Options Shunt Release: Available for remote tripping Auxiliary Contacts: For remote signaling and monitoring Undervoltage Release: Available for additional protection in case of undervoltage conditions
