Schneider Electric Rolls Out TeSys Deca Advanced Contactors

Schneider Electric unveiled its new TeSys Deca Advanced line of contactors at ProMat 2025. These contactors have been designed to have a long life and to reduce maintenance costs and energy usage. The contactors are targeted towards machine builders who can integrate these advantages into larger designs for their industrial clients.

TeSys Deca Advanced Contactor

At first glance, the TeSys Deca Advanced may seem like just another motor contactor. However, this series of contactors is full of innovations that save time and energy, reducing an operation’s costs and carbon footprint. 

One such feature is the contactor’s “one click” installation. According to Schneider Electric, this connection technology can reduce setup time by 75%. Furthermore, the controller itself is designed to make wiring installation easy, with clear labeling and ergonomically friendly wiring terminals.

The TeSys Deca Advanced contactors also feature wideband coils, enabling input voltages from 24 to 500 V DC or AC. This not only enhances compatibility between systems but, more importantly, protects the system against power surges and voltage spikes. The contactors are also rated to 100 kA of short circuit current, making it robust against accidental shorts.

The TeSys Deca Advanced contactors are available in 13 different ratings for motor loads up to 100 hp and 480 V and non-motor loads up to 160 A. There are options for reversing and non-reversing contactors. Schneider Electric provides online tools, such as EcoStruxure Motor Control Configurator, to help machine builders decide which products are required for their particular application.

HVAC Optimization

The TeSys Deca Advanced has been deployed in multiple real-world scenarios. In each of these case studies, the ability to save on maintenance costs while collecting relevant process data was a key aspect that benefitted the client.

By deploying TeSys Deca Advanced contactors, HVAC systems can be made more environmentally friendly and less costly. HVAC systems determine when to trigger the compressor for air conditioners, electric and natural gas furnaces for heating, and numerous dampers to control the flow of treated air into different spaces.

When combined with the TeSys Deca Advanced contactors, the carbon footprint of a particular system was reduced by 69%. It had the added advantage of taking up to 20% less space after installation. Ultimately, the integration of the TeSys Deca Advanced led to a smaller physical footprint, with reduced energy usage and increased fire safety.

Coil Handling

After rolling, steel coils must be moved around the rolling mill for quality control and shipping. Large overhead cranes do the heavy lifting, but they are often energy hogs.

TeSys Deca Advanced contactors can be used at higher operational frequencies, as the wideband coil reduces transients during switching. A steel mill that deployed TeSys Deca Advanced ran 2400 cycles per hour of coil operations, meaning steel coils were less likely to be pinched or burned. Furthermore, the coils could be placed more accurately during moves.

While the TeSys Deca Advanced contactors have demonstrated themselves in HVAC systems and coil handling, the contactors have been designed to be deployed in many other industrial applications to improve efficiency and productivity.
