Description
About the Product
The AU HR MCB 80A SP 240V AC 15kA C Curve is a high-rated Miniature Circuit Breaker designed to provide protection against overloads & short circuits in electrical installations. It is suitable for residential, commercial, & industrial applications where high current protection & reliability are required.
With an 80A current rating & a 15kA breaking capacity, this MCB ensures effective fault interruption even under heavy fault conditions. The C Curve tripping characteristic makes it ideal for circuits with moderate inrush currents such as motors & inductive loads.
How the MCB Works
This MCB provides protection by automatic circuit interruption:
• Monitors current flow in the circuit
• Trips when overload conditions persist
• Instantly disconnects during short circuit faults
• Prevents damage to wiring, devices, & equipment
This ensures safety & reliability of the connected electrical system.
Electrical Configuration
• Rated current: 80A
• Poles: Single pole (SP)
• Rated voltage: 240V AC
• Breaking capacity: 15kA
• Tripping curve: C Curve
• Function: Overload & short circuit protection
• Application: High load electrical circuits
Construction & Design
The MCB is engineered for durability & efficient performance:
• High breaking capacity for heavy fault conditions
• C Curve characteristic suitable for moderate inrush loads
• Compact modular design for DIN rail mounting
• High-quality arc extinguishing mechanism
• Designed for consistent & reliable tripping performance
Safety & Protection
• Protects against overload & short circuit conditions
• High 15kA breaking capacity for enhanced safety
• Prevents damage to cables & connected equipment
• Improves system reliability & fault isolation
• Ensures safe operation of high load circuits
Mounting & Durability
• DIN rail mountable for easy installation
• Suitable for distribution boards & industrial panels

FAQs
1. What does C Curve mean in this MCB?
Ans: It indicates the MCB is designed for circuits with moderate inrush currents, such as motors & inductive loads.
2. What is the significance of 15kA breaking capacity?
Ans: It means the MCB can safely interrupt very high fault currents up to 15kA.
3. Where is an 80A MCB used?
Ans: It is used in high load circuits in residential, commercial, & industrial installations.
4. Does this MCB provide overload protection?
Ans: Yes, it protects against both overload & short circuit conditions.
5. What does SP mean?
Ans: SP stands for single pole, meaning it protects one phase conductor.
6. How is this MCB installed?
Ans: It is installed on a DIN rail inside a distribution board.
7. Why is an MCB important?
Ans: It ensures electrical safety by automatically disconnecting faulty circuits & preventing damage to equipment.

Warranty
- All products listed in the price list are covered by a warranty against manufacturing defects for a period of 18* months from the date of purchase.
- For Lauritz Knudsen MCBs & Isolators mounted inside Lauritz Knudsen Distribution Boards, an extended warranty of 5 years is provided.
- In the event of a defect due to faulty workmanship or other associated reasons, the manufacturer will, at its discretion, remedy the defect or replace the faulty parts or the entire product as soon as possible, free of cost.
- This warranty is subject to proper usage and efficient maintenance and does not cover defects arising from fire, accidents, inefficient maintenance, faulty operation, or deliberate or accidental damage.
- The warranty does not cover damage to power electronic components such as thyristors & IGBTs, which primarily fail due to over-temperature or over-voltage. Users must take adequate precautions to eliminate such conditions.
- The manufacturer shall not be responsible or liable for any special, incidental, social, or consequential losses (including loss of profits), punitive damages, injury, or damages of any kind solely attributable to defect or failure of its products.
- The manufacturer shall not be liable in any manner for issues related to or failure in the performance of any other equipment to which the product is connected.
