Features and benefits:

• Adjustable thermal overload release (1.4...2 A) with CLASS 10 trip characteristic protects motors from sustained overloads
• High breaking capacity of 100 kA at 400 V reduces upstream fusing requirements
• Integrated phase failure detection guards against single-phasing damage
• Built-in disconnector function eliminates the need for a separate isolator
• ATEX certified Ex II (2) GD for use in potentially explosive gas and dust atmospheres
• Direct combination with S00 and S0 contactors simplifies motor starter assembly

Applications:

• Protection of 3-phase AC motors up to 0.75 kW at 400 V in industrial control panels
• Motor control centers and direct-on-line starters combined with S00/S0 contactors
• Installations in potentially explosive atmospheres requiring ATEX-certified protection
• Panel building where integrated disconnector functionality is required

Compliant with IEC 60529 (IP rating), IEC 60068-2-27 (shock resistance), and ATEX directive 2014/34/EU. Part of the Siemens SIRIUS 3RV2 range.
