Description
About the Product
The AU HR MCB 100A SP 240V AC 15kA C Curve is a high-capacity Miniature Circuit Breaker designed to protect electrical circuits against overloads & short circuits. It is ideal for residential, commercial, & industrial applications where high current handling & dependable protection are required.
With a 100A current rating & a high breaking capacity of 15kA, this MCB ensures safe interruption of fault currents even in demanding environments. Its C Curve characteristic makes it suitable for circuits with moderate inrush currents such as motors, transformers, & inductive loads.
How the MCB Works
This MCB ensures safety through automatic fault detection & interruption:
• Continuously monitors current flow in the circuit
• Trips during prolonged overload conditions
• Instantly disconnects supply during short circuit faults
• Protects wiring & connected equipment from damage
This guarantees reliable protection & stable operation of the electrical system.
Electrical Configuration
• Rated current: 100A
• Poles: Single pole (SP)
• Rated voltage: 240V AC
• Breaking capacity: 15kA
• Tripping curve: C Curve
• Function: Overload & short circuit protection
• Application: High current circuits
Construction & Design
The MCB is built for durability & high performance:
• High 15kA breaking capacity for heavy fault conditions
• C Curve tripping suitable for inductive & mixed loads
• Compact modular DIN rail mountable design

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.
