The Siemens 3VU1300-1MK00 motor protection circuit breaker (MPCB) serves a critical role in safeguarding electrical equipment. It allows for an adjustable current range of 4 to 6 Amps, giving flexibility for different applications. The breaker is designed with a short circuit release setting of 72 Amps, ensuring immediate response to short circuit conditions, reinforcing system safety.

Constructed with three poles, the circuit breaker includes auxiliary contacts consisting of one Normally Open (NO) and one Normally Closed (NC). The rated insulation voltage is substantial, reaching 690 Volts AC, accommodating a variety of operational environments. Rated for both 690 VAC and 250 VDC operational voltage, this device efficiently handles a range of applications.

In operation, it boasts a rated short circuit breaking capacity of 10 kA at 415 V AC without a current limiter. However, when paired with a current limiter, the breaking capacity can be significantly enhanced to 50 kA, thus further protecting connected machinery. This circuit breaker is equipped with a trip-free mechanism, allowing it to activate independently of the toggle switch position for enhanced safety.

The device operates effectively in temperatures ranging from -25°C to +55°C, ensuring reliability under varying climate conditions. Designed for DIN rail mounting, this MPCB features screw terminals for secure connections. It also promises a mechanical lifespan of 20,000 operations, making it a durable choice for motor protection.
