Contactor 4NO 40A 230V AC ESC440

40A Modular Contactor – Reliable Circuit Control

This 40A rated current and 230V AC coil voltage modular contactor is a versatile device designed to control various electrical loads. With four normally open (4NO) contacts, it is ideal for lighting, heating, ventilation, and many other installations where reliable switching of circuits is required. The device's design allows for mounting on a DIN rail, making installation quick and easy.

Functionality and Application

The ESC440 contactor features the ability to select one of three operating modes: constant on, automatic, and constant off. A manual mode selector increases the functionality of the device, allowing it to be adapted to the specific needs of the installation. This means the contactor can be used not only as an element of automatic control but also as a manual switch in emergency situations or during maintenance. The device is compatible with various types of loads, including fluorescent lamps (up to 1900 VA, and with DUO compensation up to 3000 VA) and incandescent lamps (up to 4000 W).

Safety and Technical Parameters

The contactor has a protection class of IP2X, providing basic protection against access to hazardous live parts. The rated insulation voltage is 440 V, and the impulse voltage is 4000 V, guaranteeing safe operation. The device is characterized by high electrical endurance (30,000 cycles) and mechanical endurance (1,000,000 cycles), ensuring long-term and trouble-free operation. Additionally, the compact dimensions (width 54 mm, height 85 mm, depth 60 mm) allow for easy integration into existing distribution boards and control cabinets. Suitable for operation in temperatures from -10°C to +50°C.
