Description
About the Product
The AU Modular Contactor 63A 2NO + 2NC is a high-capacity, versatile switching device designed for advanced control of electrical circuits. It is widely used in automation systems, industrial control panels, HVAC systems, & power distribution applications.
With a 63A current rating, this modular contactor is suitable for high load applications. The combination of 2NO (normally open) & 2NC (normally closed) contacts provides flexible switching options, enabling both make & break circuit control within the same device.
How the Modular Contactor Works
This modular contactor operates as an electrically controlled switching device:
• When the coil is energized, the 2NO contacts close & the 2NC contacts open
• Allows current to flow through selected circuits while interrupting others
• When the coil is de-energized, contacts return to their default state (NO open, NC closed)
• Enables precise & dynamic control of multiple circuits
This dual-contact functionality makes it ideal for complex control & automation systems.
Electrical Configuration
• Rated current: 63A
• Contact type: 2NO + 2NC
• Function: Multi-circuit switching & control
• Application: Load control, automation, & interlocking systems
• Suitable for standard AC applications
Construction & Design
The contactor is engineered for robust performance & reliability:
• Modular DIN rail mountable design
• Compact structure despite high current capacity
• High-quality contact mechanisms for reliable switching
• Designed for frequent & continuous operations
• Low noise or silent operation (depending on installation environment)
Safety & Protection
• Enables safe & efficient control of high load circuits
• Supports interlocking & control logic applications
• Reduces manual switching risks
• Provides stable & reliable operation under load
• Enhances safety & operational control in electrical systems
Mounting & Durability
• DIN rail mounting for easy installation
• Suitable for distribution boards & industrial control panels
• Compact modular construction for efficient panel usage
• Designed for long mechanical & electrical life
• Reliable under demanding & continuous operations
Application Domains
• Industrial automation systems
• HVAC & building management systems
• Motor & pump control circuits
• Power distribution systems
• Control panels & interlocking systems
Key Features
• 63A rated modular contactor for high load applications
• 2NO + 2NC contact configuration for flexible control
• Enables simultaneous switching & interlocking operations
• Compact DIN rail mountable design
• Suitable for automation & advanced control systems
• Durable & reliable construction
• Designed for frequent switching cycles
Applications
• Industrial control panels
• HVAC systems & automation
• Motor & pump control systems
• Commercial & residential power management
• Electrical interlocking & control circuits
FAQs
1. What does 2NO + 2NC mean?
Ans: It means the contactor has two normally open contacts & two normally closed contacts, allowing both switching & breaking functions.
2. What is the advantage of this contact configuration?
Ans: It allows flexible control of multiple circuits, including interlocking & automation logic.
3. Where is a 63A modular contactor used?
Ans: It is used in high load applications such as industrial systems, HVAC, motors, & power distribution.
4. Can it be used in automation systems?
Ans: Yes, it is widely used in automation & control systems for complex switching operations.
5. How is it installed?
Ans: It is mounted on a DIN rail inside a distribution board or control panel.
6. Can it operate multiple circuits at once?
Ans: Yes, it can control multiple circuits simultaneously using its NO & NC contacts.
7. Why use a modular contactor with mixed contacts?
Ans: It provides greater flexibility, allowing both activation & deactivation of different circuits within a single device.

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.
