Description
About the Product
The Tripper Isolator 40A FP 415V AC is a reliable & efficient isolation device designed for complete disconnection of three phase electrical circuits along with the neutral conductor. It is used for maintenance, servicing, & operational safety, ensuring secure isolation without providing protection against overload or short circuit faults.
With a 40A current rating, this isolator is suitable for medium load three phase systems such as motors, control panels, & distribution boards. The four pole (FP) configuration ensures simultaneous disconnection of all three phases & the neutral, providing total circuit isolation & enhanced safety.
How the Isolator Work
The isolator operates as a manual switching device:
• Allows manual ON/OFF switching of electrical circuits
• Disconnects all three phases along with the neutral simultaneously
• Provides safe isolation for maintenance & servicing
• Ensures zero current flow when switched OFF
• Does not trip automatically (manual operation only)
Technical Specifications
• Rated current: 40A
• Poles: Four pole (FP – 3 phase + neutral)
• Rated voltage: 415V AC
• Function: Circuit isolation (manual switching)
• Protection: Does not provide overload or short circuit protection
• Application: Three phase circuit isolation with neutral
Construction & Design
The isolator is built for durability & reliable performance:
• Four pole design for full system isolation including neutral
• Compact modular construction
• DIN rail mountable for easy installation
• Smooth & durable switching mechanism
• High-quality internal components for long service life
Safety & Protection
• Provides safe isolation of three phase circuits including neutral
• Ensures complete disconnection of all conductors
• Prevents accidental energization during maintenance
• Improves safety in industrial & commercial systems
• Must be used with MCB/RCBO for complete protection
Mounting & Durability
• DIN rail mountable for quick installation
• Suitable for distribution boards & control panels
• Compact design for efficient panel space usage
• Designed for long mechanical life
• Reliable under continuous medium load operation
Application Areas
• Industrial electrical systems
• Commercial installations
• Three phase distribution boards
• Motor & machinery circuits
• Control panels & switchgear
Key Features
• 40A rated isolator for three phase applications
• Four pole (FP) configuration including neutral isolation
• Manual ON/OFF switching
• DIN rail mountable design
• Compact & robust construction
• Ensures safe & complete circuit isolation
Applications
• Three phase circuit isolation with neutral
• Industrial maintenance & servicing
• Motor & equipment isolation
• Distribution panel switching
• Commercial electrical systems
FAQs
1. What is an FP isolator?
Ans: An FP (Four Pole) isolator disconnects all three phases along with the neutral for complete system isolation.
2. Does this isolator provide overload protection?
Ans: No, isolators do not provide protection. They must be used with MCBs or RCBOs.
3. Where is a 40A FP isolator used?
Ans: It is used in three phase systems requiring full isolation, including neutral, such as industrial panels & control systems.
4. Can this isolator trip automatically?
Ans: No, it operates manually & does not include any automatic tripping feature.
5. Why is neutral isolation important?
Ans: Neutral isolation ensures complete circuit disconnection, improving safety during maintenance & fault conditions.
6. What is the difference between TP & FP isolator?
Ans: TP isolators disconnect only the three phases, while FP isolators disconnect three phases plus the neutral.
7. How is this isolator installed?
Ans: It is installed on a DIN rail inside a distribution board or electrical panel.

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.
