Contactors

Electrically controlled switches used for switching an electrical power circuit. They are the standard for frequent switching of motors, heating loads, and large lighting systems.

Siemens | SIRIUS 3RT Contactors

Siemens SIRIUS contactors are the global benchmark for “Control Cabinet Efficiency.” They are designed with a modular architecture, meaning you can “snap on” auxiliary switches, timers, or surge suppressors without any tools. They are particularly favored for their IE3/IE4 readiness, meaning they are optimized for the high inrush currents of modern premium-efficiency motors.

SIRIUS 3RT20

Model Number: 3RT2015-1BB41

High packing density; integrated auxiliary contacts; up to 55 kW at 400 V.

Key Technical Specifications:

  • Specific models feature a certified “F-PLC-IN” port, allowing direct control from a safety PLC without an intermediate coupling relay.

  • Available with vibration-proof spring-cage technology that eliminates the need for periodic re-tightening of screws.

  • Optional integrated surge suppression to protect sensitive PLC outputs from the electromagnetic kickback of the contactor coil.

SIRIUS 3RT10

Model Number: 3RT1017-1BB42

Power range up to 250 kW; vacuum technology options for reduced arc wear.

Key Technical Specifications:

  • Uses vacuum interrupters in the larger sizes to prevent contact oxidation and significantly extend electrical service life.

  • The same auxiliary blocks and function modules fit across multiple frame sizes, reducing your required inventory of spare parts.

  • Rated for operation in ambient temperatures up to +60°C without significant derating of the operational current.

Schneider Electric | TeSys™ Deca & Giga

Schneider’s TeSys range is likely the most widely used contactor line in the world. They are the “sourcing favorite” because of their incredible versatility and the “Green Premium” label, which provides full transparency on the environmental impact and recyclability of the unit.

TeSys Deca (D)

Model Number: LC1D09BD

Multi-standard (UL, IEC, CSA); high switching frequency (3600 cycles/hr); 9A to 150A.

Key Technical Specifications:

  • Features NC (Normally Closed) auxiliary contacts that are “Mirror Certified,” ensuring safe feedback for machine safety circuits.

  • Patented power terminal technology that maintains permanent pressure on the cable, preventing overheating due to loose connections.

  • Designed for direct “Plug-and-Play” mounting with TeSys GV manual motor starters via specialized busbar connectors.

TeSys Giga (G)

Model Number: LC1G1154BEEA

Modular design; advanced diagnostics; wide-range electronic coils (AC/DC); 115A to 800A.

Key Technical Specifications:

  • The same unit can operate on 100V to 250V (AC or DC), drastically reducing the number of different SKUs you need to source.

  • Includes a visual indicator and a digital output to signal when the contacts are 90% worn, allowing for planned maintenance.

  • Optimized for direct connection to high-density PLC I/O modules without the need for additional power amplification.
