Safeguard your kit with this motor protection circuit breaker from Siemens. You can use it with applications such as industrial automation, power supplies and process control. It's a hardy choice that performs reliably in harsh conditions without breaking a sweat, thanks to an operating temperature range of -20°C to +60°C. Inbuilt magnetic short-circuit protection and 6kV-rated isolation stop surges from causing damage to downstream equipment. As the unit has 3 poles mean, it gives you a connectivity boost by looking after multiple circuits simultaneously. Screw terminals are on hand to achieve a reliable connection, even with vibration, and make installation straightforward.

• Current rating between 0.45 and 0.63A suits low-power applications
• Light 229g weight minimises strain on your equipment
• IP20 rating means it's touch-proof and resistant to wires or tools bigger than 12mm
• Compact dimensions of 90 (L) x 45 (W) x 81mm (D) make it a space-efficient choice
• Mechanical lifespan of 100,000 operating cycles ensures longevity

Yes. It supports screw and snap-on mounting to a DIN rail to make set-up fast and simple.
