Suitable for

• Industrial motor control panels
• Motor starter applications
• Protection of small electric motors
• Electrical distribution systems

When it may not be suitable

This device is not intended for applications requiring current ratings outside the specified 0.22-0.32A range. It is also not suitable for high-voltage power distribution systems that exceed the technical design limits of the S00 frame size.

Key specifications

• Adjustment range: 0.22-0.32A
• Size: S00
• Protection type: Thermal overload and short-circuit
• Number of poles: 3

How to use

The circuit breaker should be installed by a qualified professional on a standard mounting rail within a control cabinet. Once mounted, the thermal release current should be set to the nominal current of the motor using the adjustment dial on the front of the unit. After the electrical connections are secured, the device can be manually switched on or off using the integrated toggle mechanism.

What to consider before purchase

• Verify that the motor nominal current falls within the 0.22-0.32A range
• Ensure the S00 size fits your existing control panel layout
• Confirm compatibility with your specific motor starter configuration

Usage recommendations

Regularly inspect the device for signs of wear and perform periodic testing of the trip mechanism to ensure continued protection of your electrical equipment.
