Description
About the Product
Exora MCB 16A TP 415V AC 10kA B Curve is a triple pole miniature circuit breaker designed to protect three phase electrical circuits from overload & short circuit conditions. It is ideal for low to medium current three-phase systems requiring reliable & efficient protection.
How the Mechanism Works
The MCB operates using a thermal magnetic trip mechanism. The thermal element responds to overload conditions across each phase, while the magnetic mechanism provides instantaneous tripping during short circuit faults. All three poles trip simultaneously to ensure complete isolation of the circuit.
Electrical Configuration
This is a triple pole (TP) MCB rated at 16A current, suitable for 415V AC three-phase systems, with a 10kA breaking capacity. It features a B curve tripping characteristic, ideal for circuits with moderate inrush current.
• Safety / protection aspects
• The triple pole configuration ensures simultaneous disconnection of all three phases, enhancing safety during faults & maintenance. It protects wiring, equipment, & systems from overloads & short circuits, reducing risk of electrical hazards.
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. Its robust construction ensures consistent performance & long-term durability in industrial environments.
Application Domains
Suitable for industrial & commercial applications such as three-phase motors, control panels, lighting systems, & machinery requiring dependable overload protection.
Key Features
• Rated current: 16A
• Triple pole (TP) configuration
• Rated voltage: 415V AC
• Breaking capacity: 10kA
• B curve tripping characteristic
• Thermal magnetic protection mechanism
• Simultaneous disconnection of all three phases
• DIN rail mounting compatible
• Durable industrial-grade design
Applications
• Industrial distribution boards
• Three-phase motor protection
• Control panels
• Commercial electrical systems
• Automation & machinery circuits
FAQs
1. What is a triple pole MCB used for?
Ans: It protects three-phase circuits by disconnecting all phases simultaneously during overload or fault conditions.
2. What does 16A rating indicate?
Ans: It means the MCB is suitable for circuits carrying up to 16 amperes per phase.
3. What is B curve in MCB?
Ans: B curve is suitable for circuits with moderate inrush current in residential & light industrial applications.
4. What is 10kA breaking capacity?
Ans: It is the maximum fault current the MCB can safely interrupt.
5. Why use TP instead of SP/DP?
Ans: Triple pole MCB is required for three-phase systems where all phases must be protected & isolated together.
6. How is it installed?
Ans: It is mounted on 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.
