Schneider Electric 2.5 → 4 A TeSys Motor Protection Circuit Breaker, 690 V

Shield your electric motors from short circuits and current overload using this MPCB from Schneider Electric. When it senses an excessive current supply in the system, it automatically cuts off power to the attached circuit to protect downstream equipment from damage. A built-in selector switch lets you easily reset the unit when the fault has been cleared. Thanks to a current rating between 2.5 and 4A, this is a suitable option for low-power systems. It has a mechanical durability rating of 100,000 cycles, so you can be assured of its long-term service.

• Power dissipation of 2.5W for energy-efficient operation
• Maximum operating rate of 25cyc/h for reliable daily use
• Resistance to shocks and vibration helps prevent false tripping
• Phase failure sensitivity offers protection against phase imbalance in 3-phase motors
• Broad operating temperature range of -20°C to +60°C to withstand demanding conditions

• Office buildings
• Storage facilities
• Industrial pumps

You can mount this MPCB by clipping it to a standard 35mm DIN rail or by screwing it to a panel. As it can be installed in any position, it's a versatile choice.
