In the previous blogs, we learned about SELVO MCB & RCCB, and why these devices are essential for our industries. We learned about the above product’s different types and their working principles. So, let me present you all with a different product and yet another important device for our homes. , This blog delves into the critical role that SELVO MCB Isolators play in elevating safety standards, and ensure safe electrical installations .
SELVO MCB Trips the circuit and prevent any mishappening from faults, this can be seen through the green indication on the front of the MCB, and the dolly/knob also lowers down while the trip. But still, it is recommended not to touch the MCB just because it trips and is safe to touch. For better safety, we need disconnector which is commonly known as MAINSWITCH
These are mechanical switch devices used to ensure that an electrical circuit is completely de-energized for service or maintenance. They are operated manually and are designed to isolate a part of the circuit from the system as a safety measure. These devices do not have a mechanism for breaking the circuit under load; thus, they must only be operated under no-load conditions. That is why they are known to be Off-load devices .
Present the types of Isolators MCB to suit various applications, these are Double Pole, Three Pole & Four Pole isolators, etc. As per industry standards, each type is manufactured in three current ratings 40A, 63A & 100A.Â
1. Double-Pole Configuration: These can disconnect both the live and neutral wires, completely isolating a circuit. They’re often used in residential and commercial settings for complete circuit isolation.
2. Three-Pole Configuration: Used in three-phase systems, this can disconnect all three phases simultaneously. They’re common in commercial and industrial installations.Â
3. Four-Pole isolator  Configuration: These are similar to three-pole type but include an additional pole for neutral wire disconnection, providing complete isolation of three-phase systems with neutral.
In conclusion , SELVO MCB isolators play a crucial role in enhancing safety within electrical installations. By providing a reliable means to completely de-energize circuits for maintenance or emergency interventions, Designed to cater to a wide range of applications, from residential to heavy industrial settings, SELVO isolators are engineered to meet diverse operational needs. they significantly reduce the risk of electrical accidents and ensure the safety of personnel.Â
Their application in electrical installations not only complies with safety standards but also instills confidence among electricians and maintenance staff. SELVO’s commitment to safety is evident in their isolators’ design, making electrical systems safer, more reliable, and easier to maintain, ultimately contributing to a safer work environment and protecting valuable equipment.
