Description
About the Product
Exora MCB 63A TP 415V AC 10kA C Curve is a triple pole miniature circuit breaker designed to protect three-phase electrical circuits from overload & short circuit conditions. It is ideal for high-load industrial, commercial, & power distribution systems requiring dependable protection.
How the Mechanism Works
The MCB operates using a thermal magnetic protection mechanism. The thermal element responds to overload conditions across each phase over time, while the magnetic mechanism provides instantaneous tripping during short circuit faults. All three poles disconnect simultaneously to ensure complete circuit isolation & fault protection.
Electrical Configuration
This is a triple pole (TP) MCB rated at 63A current, suitable for 415V AC three-phase systems, with a 10kA breaking capacity. It features a C curve tripping characteristic, making it ideal for circuits with moderate to high inrush current such as large motors, compressors, & heavy inductive loads.
• Safety / protection aspects
• The triple pole design ensures simultaneous disconnection of all three phases, significantly enhancing safety during fault conditions, operation, & maintenance. It protects wiring, machinery, & electrical systems while minimizing 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 boards & control panels. Its heavy-duty construction ensures reliable long-term performance under high-load industrial conditions.
Application Domains
Suitable for industrial & commercial applications such as large motors, compressors, HVAC systems, pump systems, control panels, & main three-phase power distribution circuits.
Key Features
• Rated current: 63A
• Triple pole (TP) configuration
• Rated voltage: 415V AC
• Breaking capacity: 10kA
• C curve tripping characteristic
• Thermal magnetic protection mechanism
• Simultaneous three-phase disconnection

• Suitable for moderate to high inductive load applications
• Heavy-duty & durable design
Applications
• Industrial distribution boards
• Main three-phase power circuits
• Large motor & pump systems
• HVAC & compressor systems
• Commercial & industrial electrical panels
FAQs
1. What is a 63A TP C curve MCB used for?
Ans: It is used for protecting high-load three-phase circuits with moderate to high inrush current such as large motors, compressors, & heavy machinery.

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.
