Siemens 20 → 25 A SIRIUS Motor Protection Circuit Breaker, 20 → 690 V

Quickly shut down your motor in the event of a fault with this MPCB from Siemens. It uses thermal and magnetic breaking systems to help prevent electrical damage to your machinery caused by short circuits and overloads. A robust mechanical lifespan of 100,000 operating cycles means it's a long-lasting choice. Thanks to its adjustable input current between 18 and 25A, the device is suitable for use in heavy-duty applications. MPCBs like this are commonly used to protect printing machines and manufacturing equipment.

• Short-circuit breaking capacity of up to 100kA to withstand powerful surges
• Wide operating temperature range between -20°C and +60°C for use in demanding environments
• Compact dimensions of 97 (H) x 45 (W) x 97mm (D) to add minimal bulk to your setup
• Operating frequency of 15 cycles per hour to support continuous protection

This MPCB screws and snaps into place on standard DIN rails, making it easy to mount in your existing setup. For flexible installation, you can mount it in any position.
