Description
About the Product
The Exora MCB 16A FP 415V AC 10kA D Curve is a high-performance four pole miniature circuit breaker designed to provide reliable protection against overload & short-circuit conditions in low-voltage three-phase electrical systems with neutral. Engineered for industrial control circuits, transformer protection, motor applications, automation systems, & heavy-duty equipment, this MCB ensures safe circuit operation by automatically interrupting fault currents before they can damage wiring, electrical equipment, or connected loads. With a 16A current rating, 415V AC operating voltage, 10kA breaking capacity, & D Curve tripping characteristic, it is ideally suited for circuits with exceptionally high inrush currents where conventional B Curve or C Curve MCBs may cause nuisance tripping. The four pole configuration provides simultaneous isolation of all three phases & neutral for enhanced safety & complete system protection.
How the Mechanism Works
The Exora MCB utilizes an advanced thermal-magnetic protection system to safeguard three-phase electrical circuits from abnormal current conditions.
• The thermal element responds to prolonged overload conditions by gradually activating the trip mechanism.
• The magnetic element instantly detects high fault currents caused by short circuits & disconnects the circuit immediately.
• The D Curve characteristic allows significantly higher inrush currents before tripping compared to B Curve & C Curve MCBs.
• All three phases & neutral disconnect simultaneously during fault conditions.
• Provides reliable protection for motors, compressors, transformers, pumps, & equipment with high startup current surges.
• Ensures uninterrupted operation while minimizing nuisance tripping.
