Siemens Motor Protection Circuit Breaker, 40A - SIRIUS Series - 3RV2021-4FA10
This circuit breaker from Siemens is a safety device designed to protect against damage caused by overcurrent and short circuits. The switching device works by interrupting the flow of fault current to the circuit or equipment. As it has a power rating of 18.5kW at an operating voltage of 440V, this component can be used with heavy-duty industrial motors. It has highly sensitive contacts that quickly detect voltage and current surges and cut power immediately for enhanced electrical safety. Minimal power loss of about 7W means it's also energy-efficient. Units like this one are essential in industrial applications, such as manufacturing facilities where large conveyors are used.
• Compact dimensions of 97 (length) x 45 (width) x 91mm (depth)
• Wide operating temperature range of -20°C to +40°C for use in demanding environments
• Long mechanical service life of 100,000 switching cycles for long-lasting performance
• Screw connection for ease of installation
Can this component be installed in any environment?
The circuit breaker shouldn't be installed in high-altitude locations as its ability to cool decreases with higher air density, increasing the risk of overheating. As the component isn't waterproof, it should only be used in dry environments.
