Family Overview
Selection And Application Context
Reliable electrical isolation is fundamental for safety in any power distribution system. Our range of isolator switches is specifically engineered to provide a secure means of circuit disconnection, preventing accidental re-energization during critical work. These switches are built for durability, featuring an electrical and mechanical life of 20,000 cycles, ensuring long-term performance. With a rated voltage of 240/415V and suitability for 50/60Hz frequencies, they are versatile for a wide array of setups. Each isolator switch offers an IP20 degree of protection, safeguarding against solid objects and ensuring operational integrity within panels.
Designed for straightforward DIN-rail mounting, installation is efficient, making them a preferred choice for panel builders and electrical contractors. Their robust construction and adherence to IEC60947-3 standards confirm their suitability for rigorous commercial distribution panels and industrial isolation applications. We also offer ODM and private label manufacturing support, allowing for tailored solutions to meet specific project requirements. Our commitment to quality ensures that each isolator switch contributes to a safer, more manageable electrical infrastructure.
