Series-1S: High-Performance Molded Case Circuit Breakers for Industrial Automation
Series-1S represents a premium line of molded case circuit breakers (MCCBs) designed for demanding industrial automation and electrical distribution applications. These devices are engineered to provide reliable overcurrent protection, short-circuit interruption, and isolation in low-voltage power systems up to 690V AC. Key technical specifications include rated currents from 16A to 1600A, breaking capacities up to 100kA at 415V AC, and configurations from 3-pole (3P) to 4-pole (4P) with fixed or draw-out mounting options. The series incorporates advanced arc-extinguishing technology, electronic or thermal-magnetic trip units, and a wide range of accessories such as shunt trips, undervoltage releases, auxiliary contacts, and motor operators. Series-1S breakers comply with international standards IEC 60947-2 and UL 489, ensuring global acceptance and safety.
These circuit breakers are primarily deployed in main distribution boards, sub-distribution panels, motor control centers (MCCs), and generator protection systems within industrial plants, commercial buildings, and infrastructure projects. They are ideal for protecting transformers, capacitors, motors, cables, and busbars against overloads and short circuits. Typical sectors include manufacturing, oil and gas, mining, water treatment, data centers, and renewable energy installations. The draw-out version facilitates easy maintenance and replacement without de-energizing the entire system, making it suitable for critical processes requiring high uptime.
The Series-1S category encompasses several subcategories based on frame size and breaking capacity. Key article codes include OM3801-16A, OM3801-25A, OM3801-40A, OM3801-63A, OM3801-100A, OM3801-160A, OM3801-250A, OM3801-400A, OM3801-630A, OM3801-800A, and OM3801-1600A. The code structure follows the pattern: OM3801-[Rated Current in Amperes], where the suffix indicates the nominal current rating. For example, OM3801-100A denotes a 100A breaker. Additional variants include electronic trip units (e.g., OM3801-250A-ETU) and draw-out versions (e.g., OM3801-630A-DO). These breakers are available with fixed or adjustable trip settings, and with or without integral earth fault protection.
