Siemens OLR3200 is a thermal overload relay designed to provide reliable motor protection against phase failure, overload, and phase imbalance. It is rated for a maximum operational voltage of 690V AC and features an adjustable current setting range, typically from 0.1A to 32A, to match specific motor full-load amperage. The relay is constructed with a durable, compact housing and utilizes a bi-metallic tripping mechanism for precise thermal response, complying with international standards including IEC 60947-4-1. This device is commonly applied in industrial control panels, motor control centers (MCCs), and machinery for safeguarding three-phase AC motors in demanding environments.
