Features and benefits:

• 100 kA short-circuit breaking capacity (Icu and Ics) across all voltage ratings up to 690 V provides high-level protection in demanding installations.
• Thermal overload release with phase failure detection guards against single-phase motor operation.
• Disconnector functionality allows the circuit breaker to serve as a local isolator for the protected motor circuit.
• Compatible with size S00 and S0 contactors for direct combination in motor starter assemblies.
• ATEX-rated (Ex II (2) GD) for use in potentially explosive atmospheres.
• Suitable for safety-related switching OFF functions, supporting safety-critical applications.

Applications:

• Protection of small three-phase AC motors rated up to 0.18 kW at 400 V in industrial control panels.
• Motor starter combinations with size S00 or S0 contactors in compact switchgear assemblies.
• Motor circuit protection in installations where ATEX compliance is required.
• Applications requiring local disconnection and overload/short-circuit protection in a single device.

Compliant with IEC 60947-4-1 and IEC 60529. Part of the Siemens SIRIUS 3RV2 range.
