ELB125H Series Miniature Circuit Breaker
Product Details
Product Descriprion
The ELB125H series is purpose-built for high-current circuits, making it ideal for applications where standard MCBs fall short. Its thermal-magnetic tripping mechanism delivers precise overload and short-circuit protection for high-inrush loads, with selectable Type C curves for general loads and Type D curves for motor-driven equipment. The 10kA breaking capacity ensures dependable performance even under severe fault conditions, making it suitable for industrial switchboards, elevator power circuits, and HVAC systems.
Key to its industrial-grade design is the robust construction, featuring flame-retardant, heat-resistant imported plastic housing that withstands harsh operating conditions. With a compact 27mm pole width, it maximizes panel space utilization, while pin terminals accommodate both flexible (1.5–35mm²) and rigid (1–50mm²) cables, simplifying installation in large-scale systems. Temperature compensation ensures stable performance across -5°C to +60°C, even in fluctuating industrial environments.
Designed for long-term reliability, the ELB125H features a specially engineered tripping mechanism that extends service life, backed by compliance with strict EN/IEC 60947-2 standards. For B2B partners, we offer customized solutions, including bulk packaging, project-specific labeling, and complete certification documentation, to support your industrial and commercial projects.
