3RT1055-0LA06

The Siemens SIRIUS 3RT1055-0LA06 is an S6 frame contactor. It does not include the operating coil mechanism at the factory and requires a matching voltage coil to operate. The main circuit is rated at 150A AC-3, corresponding to approximately 75kW at 400V. It also has 2 normally open and 2 normally closed auxiliary contacts, making it suitable for applications where the coil needs to be customized.

Siemens SIRIUS 3RT1055-0LA06 S6 contactor body (without coil)

Product Positioning

The 3RT1055-0LA06 is the "body" version of the Siemens SIRIUS S6 large contactor. It does not include an operating coil at the factory; a matching voltage coil is required to complete the contactor. This design allows the same 150A body to be flexibly paired with different control voltages. Kensun Motors can assist in suggesting suitable coil combinations.

Core Product Advantages and Features

S6 Large Contactor Body

It belongs to the Siemens SIRIUS 3RT10 series S6 frame body, and the main circuit specifications are the same as the 150A model in the same series.

Operating coil not included.

The main body does not include the coil mechanism; a corresponding voltage coil assembly must be ordered separately for assembly. It is not a fixed voltage model.

AC-3 rated 150A/75kW

The main circuit AC-3 has a rated current of 150A, corresponding to approximately 75kW at 400V, and its load-bearing capacity is consistent with that of the standard product.

2NO+2NC auxiliary contacts

The main body has two sets of normally open and two sets of normally closed auxiliary contacts built in, and it can be put into use after the coil is assembled.

Flexible coil specifications

A compatible coil can be added according to the control voltage to improve the commonality of spare parts and simplify inventory management.

Authorized Channel Quality Assurance

Kenxin Motors provides original factory parts and optional coil consultation to avoid delays caused by incorrect specification selection.
