Description
About the Product
Exora MCB 25A SP 240V AC 10kA B Curve is a miniature circuit breaker designed to protect electrical circuits from overload & short circuit conditions. It is widely used in low voltage distribution systems for residential & commercial installations.
How the Mechanism Works
The MCB uses a thermal magnetic tripping mechanism. The thermal element protects against overload conditions, while the magnetic mechanism provides instantaneous tripping during short circuit faults, ensuring safe circuit disconnection.
Electrical Configuration
This is a single pole (SP) MCB rated at 25A current, suitable for 240V AC systems, with a 10kA breaking capacity. It features a B curve tripping characteristic, ideal for circuits with low to moderate inrush currents.
• Safety / protection aspects
• The MCB provides reliable protection against overload & short circuit faults, preventing wiring damage & reducing fire risks. It ensures safe operation of electrical systems & connected equipment.
Construction & Design
A compact insulating body integrates the operating mechanism, contacts, arc-control components, terminals, & trip elements for reliable circuit protection.
Safety & Protection
Provides circuit isolation & overcurrent protection when correctly selected, coordinated, installed, & operated within its published ratings.
Mounting & Durability
Designed for standard DIN rail mounting, the breaker allows quick installation in distribution boards. Its robust construction ensures long-lasting & dependable performance.
Application Domains
Suitable for residential & commercial electrical systems including power circuits, socket outlets, & medium-load appliances.
Key Features
• Rated current: 25A
• Single pole (SP) configuration
• Rated voltage: 240V AC
• Breaking capacity: 10kA
• B curve tripping characteristic
• Thermal magnetic protection mechanism
• DIN rail mounting compatible
• Durable & reliable design
Applications
• Residential distribution boards
• Socket outlet circuits
• Medium-load appliances
• Office & commercial panels
• General low-voltage protection systems
FAQs

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.
