The three-phase “4 in 1” solid state reversing contactors are used for motors with an engine power of up to 4 kW. Four functions are combined in one device: right contactor, left contactor, motor protection relay, and emergency stop up to category 3. Unlike mechanical switching devices, solid state contactors do not contain any moving parts providing them with a much longer switching life and great reliability.
This product is a solid state replacement for electromechanical reversing contactor combinations using motor protection relays. It also replaces competitive solid state contactors. Its combination of functionality, size, and affordability make it unique to the market.
Installation is simplified considerably and a significant amount of space is saved on the DIN rail.
CONTACTRON 4-in-1 combines the following four functions into one device:
Right Contactor (Forward)
Left Contactor (Reverse)
Motor Overload Relay (Protection Relay)
Emergency Stop Contactor
The 22 mm wide design saves 75 percent more DIN rail space than reversing mechanical contactors.
No contact wear from moving parts reduces maintenance costs and creates a long switching lifetime.
The Contractron ensures reliable switching even under harsh ambient conditions.
