Siemens 4.5 → 6.3 A SIRIUS 3RV Motor Protection Circuit Breaker

Use this motor protection circuit breaker (MPCB) from Siemens to protect your motor from damage during a power failure or system breakdown. It’s designed to initiate a full power-down if current overloads or short circuits are detected. As the unit has an IP20 (ingress protection) rating, it's finger-safe to prevent electric shocks and is protected against objects larger than 12mm in size. You can use this MPCB to protect motors in applications such as air-conditioning units and industrial manufacturing.

• Operating voltage of 690V for use with high-voltage equipment
• Compact dimensions of 97 (height) x 45 (width) x 96mm (depth) for installation in areas where space is limited
• Wide operating temperature range of -20°C to +60°C for safe industrial use
• Top and bottom electrical connectors for simple mains power connection

This MPCB is designed for mounting on a standard 35mm DIN rail. For versatile installation, you can either screw it in place or use its snap-in technology for tool-free mounting.
