Description
Detail
Fail-safe direct starter, 3RM1, 500 V, 0.55 – 3 kW, 1.6 – 7 A, 24 V DC, spring-type terminals Fail-safe direct starter SIRIUS 3RM1 for functional switching of three-phase motors. Narrow design, multifunctional, with electronic overload protection, durable and energy-efficient hybrid switching technology, small number of different devices due to wide setting ranges, easy installation thanks to low wiring requirements, fast error diagnostics due to LED display, innovative enclosure concept, e.g. with labeled cover caps and removable terminals. Available as direct or reversing starter, optionally with ATEX certification and safety-related shutdown, with various motor current ranges, supply voltage types and connection technologies. An extensive range of accessories, such as device connector, fuse module, infeed system or sealable covers, completes the system. Getting started in minimum space – SIRIUS 3RM1 motor starters.
