Motor protection circuit breakers from LOVATO ELECTRIC are designed for the reliable protection of motors against overloads, short circuits, and phase failures. These devices, also known as manual motor starters or motor protective switches, combine thermal and magnetic tripping mechanisms to ensure precise and repeatable protection. Key technical parameters include rated operational currents from 0.1A up to 100A, breaking capacities up to 50kA at 400V (LCU), and a wide range of pole configurations (typically 3P). The SM1 series features standard short-circuit tripping indicators for immediate visual status. All units comply with IEC/EN 60947 and are suitable for isolation, making them a robust choice for demanding industrial environments.
These circuit breakers are primarily used in motor control centers (MCCs), distribution panels, and direct-on-line starter assemblies. They are essential in sectors such as manufacturing, water treatment, HVAC, and material handling, where protecting induction motors from electrical faults is critical. Their high breaking capacity often eliminates the need for upstream fuses, simplifying panel design and reducing installation costs. They are also ideal for integration into automated production lines and pump stations.
The main subcategories include the SM1 series (e.g., SM1-32, SM1-63, SM1-100) and the SM2 series. Article codes typically follow the pattern 'SM1-XXX' where 'XXX' denotes the rated current (e.g., SM1-32 for 32A). Other key items are the SM1-100 for higher current applications. These breakers are available with various accessories like auxiliary contacts, shunt trips, and undervoltage releases, but the core units themselves are the focus here.
