Siemens Meiko 3rv1011-0ja25 Motor Overload Protector

What is the Siemens 3RV1011-0JA25 Motor Overload Protector?

Siemens 3RV1011-0JA25 is a tiny yet high-capacity motor protection circuit breaker that is part of Siemens’ acclaimed 3RV10 series. It is designed particularly to safeguard miniature motors from damage caused by prolonged overloads, phase loss, and short-circuit faults. Its durable construction and trustworthy operation make it an ideal solution for millions of industrial and business uses.

Key Features of Siemens 3RV1011-0JA25

Let’s dig deeper into the characteristic features of this device:

1. Thermal and Magnetic Protection
Fitted with both thermal and magnetic tripping mechanisms, it safeguards motors against not only prolonged overloads but also instantaneous short circuits. The thermal part allows for a time delay against minor overloads, whereas the magnetic part acts instantly against heavy faults.

2. Adjustable Current Range (0.28 – 0.4A)
The 3RV1011-0JA25 is optimized for motors whose rated operating current is between 0.28 and 0.4 amps, so it is best for small-sized motors of sensitive applications.

3. Compact DIN Rail Mounting
Because it is compact and DIN rail-mountable, mounting is fast and easy, even with cramped control panels. This saves space and reduces wiring complexity.

4. Trip Class 10
With a Trip Class 10, the protector is calibrated for normal industrial motor protection, providing the right response times in coordination with motor start-up characteristics.

5. Built-in Auxiliary Contacts
The unit has built-in auxiliary contacts to offer signaling capabilities for remote monitoring and control and increase the level of intelligence in your control system.

6. High Breaking Capacity
Designed to handle short circuit currents of up to 100 kA, this breaker provides high reliability and safety under fault conditions.
