LSiS DH1-S Rotary Handle for TD100-160 Circuit Breakers

The LSiS DH1-S rotary handle is a specialized control accessory engineered for seamless integration with TD100 and TD160 series molded case circuit breakers. This mechanism facilitates manual operation of the circuit breaker directly from the front of an electrical enclosure, providing a robust and ergonomic interface for switching tasks. Designed for industrial and commercial electrical distribution systems, it ensures reliable performance and improved operational safety by allowing users to toggle the breaker status without opening the panel door.

Advantages

The primary benefit of the LSiS DH1-S rotary handle is its ability to enhance user safety by enabling external control of the circuit breaker. Its durable construction ensures long-term reliability even in demanding environments, while the intuitive design allows for quick and precise switching. The mechanism is engineered for straightforward installation, minimizing downtime during setup and maintenance. By providing a secure and stable grip, it reduces the risk of accidental operation and ensures that the breaker status is clearly visible and accessible to authorized personnel.

Suitable for

• Industrial electrical distribution panels
• Commercial building power management systems
• Control cabinets requiring external manual breaker operation
• Retrofitting existing TD100 and TD160 circuit breaker installations

When it may not be suitable

This rotary handle is specifically designed for the TD100 and TD160 series circuit breakers and is not compatible with other breaker models or brands. It is intended for manual operation and does not provide motorized or remote switching capabilities.

Key specifications

• Compatibility: TD100 and TD160 series molded case circuit breakers
• Operation type: Manual rotary mechanism
• Application: Front-panel mounting
• Material: Industrial-grade durable components

How to use

To install the LSiS DH1-S rotary handle, ensure the electrical system is de-energized to maintain safety. Follow the manufacturer's installation instructions to mount the handle mechanism onto the circuit breaker and align it with the panel door cutout. Once secured, the handle allows you to toggle the breaker between the ON, OFF, and TRIPPED positions by rotating the handle to the corresponding indicator. Always verify that the handle is properly aligned and that the breaker mechanism engages fully before restoring power to the system.

What to consider before purchase

• Verify that your circuit breaker model is part of the TD100 or TD160 series
• Ensure there is sufficient space on the panel door for the handle installation
• Check that the mounting depth of your enclosure is compatible with the handle shaft length

Usage recommendations

Regularly inspect the handle mechanism for any signs of wear or mechanical resistance to ensure smooth operation. Keep the area around the handle clear of obstructions to allow for immediate access during emergency situations.
