Key Features Circuit Breaker Type: Molded case circuit breaker (fixed, non‑adjustable trip). Poles: 3 (three‑phase) configuration for three‑phase systems. Trip Unit: Thermomagnetic (TMD) release — inherent overload and short‑circuit protection via thermal and magnetic mechanisms. Mounting: Fixed‑mount with front terminals for straightforward wiring. Industrial Use: Suitable for power distribution and protection in control panels and switchboards. Electrical Specifications Rated Current (In): 16 A — nominal continuous current capacity of the protection unit. Rated Operational Voltage: Up to 690 V AC (typical low‑voltage network). Up to 500 V DC (with appropriate pole series). Insulation Voltage (Ui): 800 V — withstands system insulation requirements. Impulse Withstand Voltage (Uimp): 8 kV — robust against transient voltage surges. Short‑Circuit Protection: Rated Instantaneous Short‑Circuit Setting (Ii): 450 A magnetic threshold. Breaking Capacities: Service and ultimate short‑circuit breaking capacities vary with voltage level (higher values at lower voltages, lower at higher voltages). Rated Frequency: 50/60 Hz operation. Rated Uninterrupted Current (Iu): 160 A — conductor thermal rating for the breaker frame. Performance & Endurance Electrical Durability: Designed for thousands of make/break cycles at rated load. Mechanical Durability: High operational life for repeated switching. Opening Characteristics: Fast response under specified overload and fault conditions. Mechanical & Installation Connection Type: Front screw terminals for secure conductor clamping. Compact Form Factor: Space‑efficient size for panel layouts. Weight & Size: Moderate footprint suitable for distribution boards and machine panels. Typical Applications Three‑phase circuit protection in industrial and commercial power distribution systems. Branch‑circuit safeguard for motors, feeders, transformers, and general loads. Protection in control panels and machinery electrical sections. Overload and short‑circuit protection where a basic, robust circuit breaker is needed.
