Contactors are necessary for remote switching on and off of powerful electrical equipment. They ensure the safety and automation of technological processes, and are a key component for managing electrical loads in industrial networks. The contactors are based on the electromagnetic principle, which guarantees a high response rate and durability.
Kinds
- Power contactors are designed for switching high-power loads, such as electric motors or lighting systems. They are designed for high currents and frequent operation.
- Magnetic starters, which are a type of contactors, are additionally equipped with a thermal relay to protect the motors from overloads and phase interruptions. This makes them the main device for controlling and protecting large asynchronous electric motors.
- Reversible models allow you to change the direction of rotation of the engine. They are two starters connected electrically and mechanically to prevent simultaneous activation.
- A separate group consists of modular contactors for mounting on a DIN rail in switchboards. They are often ordered for remote control of lighting, ventilation or heating in buildings.
Key Features
The basic parameter when choosing a contactor is the rated current. In our catalog there are models from 0.1 to 800 A.
Additionally taken into account:
- Number of closing and opening contacts: options from 0 to 4 are available.
- The type of coil switching current: direct, alternating or universal.
- Design: standard or modular is possible for easy mounting on a DIN rail.
- Application category: Defines the type of switched load, which is critical for correct operation and durability.
- Degree of protection (IP): responsible for reliable operation in conditions of high dust or humidity.
The correct selection of the contactor according to these characteristics guarantees stable and long-term operation of the device in specific conditions.
