This compact device, belonging to the S00 size category, is specifically designed to safeguard industrial equipment against the risks of short circuits and thermal overloads. By offering a reliable disconnection mechanism, it ensures that motors operate within safe parameters, thereby extending the service life of your electrical infrastructure.

Advantages

This motor circuit breaker stands out due to its robust construction and high operational reliability in demanding industrial environments. The adjustable thermal release range allows for fine-tuned protection tailored to the specific current requirements of the connected motor. Its compact design facilitates space-saving installation within control cabinets, while the integrated auxiliary contacts provide essential feedback for monitoring and control systems, enhancing overall plant safety and operational transparency.

Suitable for

• Protection of small industrial motors
• Control cabinet installations
• Overload and short-circuit protection in automation systems
• Electrical distribution panels

When it may not be suitable

This device is not intended for use with motors requiring a nominal current outside the 0.22-0.32A range. It is also not suitable for high-voltage applications or environments that exceed the specified environmental protection ratings for this series.

Key specifications

• Number of poles: 3
• Current setting range: 0.22-0.32A
• Size: S00
• Protection type: Thermal and magnetic release

How to use

The device is designed for mounting on standard DIN rails within a control panel. Ensure that the power supply is disconnected before installation. Connect the incoming power lines to the top terminals and the motor leads to the bottom terminals. Once installed, adjust the thermal release dial to the specific full-load current rating of your motor using a screwdriver. After wiring, the device can be manually switched on or off using the front-facing toggle.

What to consider before purchase

• Verify the nominal current of your motor matches the 0.22-0.32A range
• Ensure the S00 size fits your existing control cabinet layout
• Check compatibility with your control system for auxiliary contact requirements

Usage recommendations

Regularly inspect the circuit breaker for signs of wear or thermal damage and perform periodic testing of the trip mechanism to ensure continued operational safety.
