Why Choose the ABB 1SDA066579R1 RHS L Left-Side Rotary Handle?
The ABB 1SDA066579R1 is a standard left-side lateral rotary handle operating mechanism designed for ABB SACE Tmax XT1 and XT3 moulded-case circuit breakers. As part of the ABB SACE Tmax XT accessory range, it provides a practical side-operated solution for applications where the circuit breaker needs to be controlled from the left-hand side of an enclosure or switchboard.
The RHS L mechanism provides left lateral manual operation and incorporates a padlocking device on the circuit breaker. This allows the breaker operating mechanism to be secured during appropriate isolation and maintenance procedures while providing an alternative operating arrangement where conventional front-mounted operation is unsuitable.
Designed specifically for fixed and plug-in Tmax XT1 and XT3 circuit breakers, the 1SDA066579R1 uses ABB's standard handle configuration and is suitable for professional low-voltage switchboards, control panels and machinery enclosures requiring reliable side access to the breaker operating mechanism.

- Designed in accordance with IEC 60947-2 and UL 489.
Reliable Left-Side Circuit-Breaker Operation
A lateral rotary operating mechanism allows a moulded-case circuit breaker to be manually controlled from the side rather than solely from its conventional front operating position. This can provide greater flexibility when designing switchboards, machinery panels and electrical enclosures where space, accessibility or equipment layout makes side operation preferable.
The ABB 1SDA066579R1 provides a standard left-side operating arrangement specifically engineered for fixed and plug-in SACE Tmax XT1 and XT3 circuit breakers. Its integrated padlocking capability also helps support controlled isolation practices when the breaker must be secured against unintended operation.
Typical Applications
- Industrial low-voltage switchboards and distribution panels.
- Left-side operation of SACE Tmax XT1 and XT3 circuit breakers.
- Electrical control cabinets and machinery panels.
- Enclosures where conventional front breaker access is restricted.
- Industrial isolation and manual switching applications.
- Commercial and infrastructure power-distribution equipment.
