Siemens 1.4 → 2 A SIRIUS Motor Protection Circuit Breaker, 690 V

Turn this MPCB from Siemens to protect your industrial motors against faults. Thanks to its integrated overload and short-circuit monitoring, it cuts power to your motor in the event of electrical hazards to minimise the risk of damage to downstream equipment. For ease of installation, the unit snaps and screws into place on a DIN rail and can be mounted in any position for flexibility. Its compact dimensions of 97 (H) x 45 (W) x 97mm (D) allow you to maximise packing space on your rail. You can use MPCBs like this one to protect pumping systems and automated assembly lines.

• Front-mounted handle for easy resetting
• Short-circuit breaking capacity of up to 100kA to withstand powerful electrical surges
• Mechanical service life of 100,000 switching cycles for long-lasting operation
• Wide operating temperature range of -20°C to +60°C for use in demanding environments

This MPCB uses the screw termination method, helping to ensure a secure electrical connection, even if your equipment is subject to vibration.
