Siemens 2.8 → 4 A SIRIUS Motor Protection Circuit Breaker

To keep your industrial applications safe, put this motor protection circuit breaker from Siemens on guard. The unit boosts safety by cutting power to the attached circuit when a fault occurs, helping to protect equipment from damage and prevent injuries. A voltage rating of 690V AC means this device has the muscle to handle demanding operations. And thanks to its surge voltage resistance rating of 6kV, you can rest assured it stands up to powerful spikes in voltage. Compact dimensions of 90 (H) x 45 (W) x 75mm (D) mean it fits right in with crowded setups. You'll find this MPCB used with everything from industrial pumps and mills to medical systems.

• Built-in protection against short circuits for increased electrical safety
• Wide operating temperature range between -20°C and +60°C for use in harsh conditions
• Trips in 10 seconds or less for a rapid response to faults
• Snaps onto a DIN rail to make installation a breeze

This MPCB has a long mechanical lifespan of 100,000 switching cycles, so you can be sure it's built to last.
