ELB6K Miniature Circuit Breaker(MCB)
Product Details
Product Descriprion
The ELB6K series is engineered with a focus on compact performance, making it a go-to choice for panel builders, system integrators, and OEM partners who need to maximize space in their designs. Its thermal-magnetic tripping mechanism provides tailored protection for lighting, general, and motor loads, with temperature compensation ensuring stable operation across typical environmental conditions.
Key to its design is the slim profile, which allows for high-density installation on standard 35mm DIN rails without sacrificing performance. Lug/pin terminals accommodate a wide range of conductor sizes (up to 35mm² rigid), simplifying wiring in both new and retrofit applications. The visible contact position indicator and color-coded handles enhance safety and quick identification, critical for maintenance in dense panels.
With a 4,000-cycle electrical lifespan and durable construction, the ELB6K is built for long-term use in continuous applications. We offer B2B-friendly terms, including custom packaging, neutral labeling, and full certification documentation, to support your brand and project requirements.
