CTX³ industrial contactors
There are requirements for control and protection of motors in all sectors: heating, ventilation and air conditioning in commercial buildings; pumps, compressors, conveyors and machines in industrial buildings, etc. Legrand’s new motor circuit breakers, contactors and thermal relays provide a response for all these applications. Their high performance levels, perfect complementarity, compact size, ease of mounting, wide range of auxiliaries, etc. make them suitable for installation in all distribution boards and control enclosures.
CTX³ 3-pole contactors up to 800 A (AC 3)
A perfect solution for switching motors and controlling circuits for the most demanding applications.
Main characteristics:
- Connection plates for bars or lugs
- Pre-fitted auxiliary contact blocks (2 per contactor). Additional auxiliary contact blocks can be fitted on the right or left of the contactors
- IP 2X screw terminals up to 40 A, screw or cage terminals from 50 to 150 A
- Integrated auxiliary contacts
RTX³ thermal relays up to 800 A
RTX³ thermal relays provide protection against overloads, long starting times and prolonged stalling of the motor.
Main characteristics:
- Trip indicator
- Off/test button
- Thermal protection trip threshold setting
- Reset button and mode selector: automatic (A)/manual (H)
- Sealable protective cover
- Integrated auxiliary contacts (1NO+1NC)
