Description
About the Product
The AU HR MCB 100A FP 415V AC 15kA C Curve is a high-capacity Miniature Circuit Breaker designed to protect three phase electrical systems against overloads & short circuits. It is ideal for industrial, commercial, & high-load applications requiring dependable protection & complete circuit isolation.
With a 100A current rating & a high breaking capacity of 15kA, this MCB ensures safe interruption of fault currents even under severe conditions. The four pole (FP) configuration provides protection & isolation for all three phases along with the neutral, ensuring comprehensive system safety.
How the MCB Works
This MCB provides automatic protection through continuous monitoring:
• Monitors current flow across all three phases & neutral
• Trips during sustained overload conditions
• Instantly disconnects supply during short circuit faults
• Simultaneously isolates all phases & neutral
This ensures safe operation & protection of electrical systems & connected equipment.
Electrical Configuration
• Rated current: 100A
• Poles: Four pole (FP – 3 phase + neutral)
• Rated voltage: 415V AC
• Breaking capacity: 15kA
• Tripping curve: C Curve
• Function: Overload & short circuit protection
• Application: High-capacity three phase systems
Construction & Design
The MCB is engineered for durability & industrial-grade performance:
• Four pole design for complete system isolation
• High 15kA breaking capacity for heavy fault conditions
• C Curve tripping suitable for inductive & moderate inrush loads
• Compact modular design compatible with DIN rail mounting
• Advanced arc extinguishing mechanism
• Reliable & consistent tripping performance
Safety & Protection
• Protects against overload & short circuit faults
• Ensures simultaneous disconnection of all phases & neutral
• Reduces risk of equipment damage & electrical hazards
