Siemens 22 → 32 A Sirius Innovation Motor Protection Circuit Breaker

Need a reliable guardian to protect your industrial motor? Put this Siemens circuit breaker on duty. It trips to cut the power supply to your device in the event of a short circuit or overload, preventing damage to boost your equipment's lifespan. Thermoplastic housing offers a reliable shield against mechanical impact and abrasion, so you can rest assured of long-term service. This material also serves as an insulator to protect you from electric shocks. Thanks to a rotary handle with marked contact positions, you can easily monitor this unit and reset it after it's tripped. You'll find it used in the robotics and automation industry.

• DIN rail mounting method is simple and doesn't need complex tools, saving time and effort
• Broad operating temperature range between -20°C and +60°C for use in demanding settings
• Electrical endurance of up to 50,000 switching cycles for long-term performance

If your circuit breaker keeps tripping even though there's no sign of a short circuit or overload, you may need to check for loose wires that can cause an arc fault.
