モータ保護回路ブレーカ Siemens 9 → 12 A SIRIUS

This circuit breaker from the Siemens SIRIUS Innovation series protects your electric motors from overloads. It's designed to work with contactors and other protective devices to cut the current supply to your equipment when a fault occurs. You can reset it quickly with the easy-to-use knob at the front. The unit has a temperature tolerance range of -20°C to +60°C, so it's suitable for use in challenging environments. Its mechanical service life of 100,000 operating cycles means you can rely on it for long-term performance. Thanks to a current rating of 12A, it's a safe choice for demanding industrial applications.

• Insulation voltage rating of 690V for optimal electrical safety
• Low power loss of 7W for energy efficiency
• Trip class 10 to indicate that it will trip in 10 seconds or less when supply current is six times the thermal current rating, for quick responses

For short-circuit protection, the circuit breaker has an integrated 63A fuse that breaks to cut current flow when the fault occurs.
