Description
About the Product
Exora MCB 40A FP 415V AC 10kA B Curve is a four pole miniature circuit breaker designed to protect three phase electrical systems with neutral from overload & short circuit conditions. It ensures complete circuit isolation by disconnecting all three phases along with the neutral simultaneously.
How the Mechanism Works
The MCB operates using a thermal magnetic protection mechanism. The thermal element detects overload conditions across all phases, while the magnetic mechanism provides instantaneous tripping during short circuit faults. In the four pole configuration, all conductors including neutral are disconnected together.
Electrical Configuration
This is a four pole (FP) MCB rated at 40A current, suitable for 415V AC three-phase systems, with a 10kA breaking capacity. It features a B curve tripping characteristic, making it ideal for circuits with moderate inrush currents.
• Safety / protection aspects
• The four pole design ensures complete isolation of all three phases & neutral, significantly enhancing safety during fault conditions & maintenance. It protects electrical systems, wiring, & connected equipment while reducing risks of electrical hazards & fire.
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 DIN rail mounting, the breaker allows easy installation in three-phase distribution panels. Its robust & heavy-duty construction ensures long-term durability & reliable performance even under high-load operating conditions.
Application Domains
Suitable for industrial & commercial applications such as three-phase distribution systems, machinery, HVAC systems, control panels, & electrical installations requiring full isolation including neutral.
Key Features
• Rated current: 40A
• Four pole (FP) configuration
• Rated voltage: 415V AC
• Breaking capacity: 10kA
• B curve tripping characteristic
• Thermal magnetic protection mechanism
• Simultaneous disconnection of three phases & neutral
• DIN rail mounting compatible
• Heavy-duty & durable design
Applications
• Industrial distribution boards
• Three-phase systems with neutral
• HVAC systems & heavy machinery
• Control panels
• Commercial electrical installations
FAQs
1. What is a four pole MCB used for?
Ans: It protects three-phase circuits & disconnects all phases along with neutral simultaneously.
2. What does 40A rating indicate?
Ans: It indicates the MCB is suitable for circuits carrying up to 40 amperes per phase.
3. What is B curve in MCB?
Ans: B curve is suitable for circuits with moderate inrush current in industrial & commercial applications.
4. What is 10kA breaking capacity?
Ans: It is the maximum fault current the MCB can safely interrupt.
5. Why use FP instead of TP?
Ans: FP MCB provides enhanced safety by isolating the neutral along with all phases.
6. How is it installed?
Ans: It is mounted on standard DIN rails inside three-phase distribution boards.

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.
