Contactor 4NO 25A 230V AC ESC425

Modular contactor for load control

This four-pole contactor (4NO) with a rated current of 25A, designed to operate at 230V AC, is a reliable solution for controlling various electrical circuits. It is ideal for both home installations and more demanding industrial applications. The device is characterized by high mechanical and electrical strength, ensuring long-lasting and trouble-free operation.

Functionality and application

The ESC425 contactor enables effective control of lighting, ventilation systems, heating and other electrical devices. Thanks to four normally open (NO) contacts, it allows independent switching on and off of several circuits simultaneously. The possibility of use in circuits with various types of loads – bulbs, fluorescent lamps, and even motors – makes it a universal element of electrical installation. Additionally, this contactor is compatible with various electrical installation standards, making it easier to integrate with existing systems.

Key features and benefits

• High switching capacity: The maximum switching power for fluorescent lamps is 950 VA (up to 1990 VA with DUO compensation), and for incandescent lamps – 1900 W. This guarantees stable operation even under high loads.
• Versatility: Designed to work with AC-7a/AC-7b loads, which means a wide range of applications in various types of installations.
• Compact dimensions: A width of only 2 modules (35.75 mm) makes it easy to mount in distribution boards and control cabinets.
• Safety: Protection class IP2X provides basic protection against contact and ingress of solid objects.
• Durability: Mechanical endurance of 100,000 cycles and electrical endurance of 30,000 cycles guarantee a long service life of the device.
• Easy installation: Mounting on a DIN TH-35 rail makes installation easier and faster.
• Low power loss: Total power loss for rated current is only 7.5 W, which translates to energy savings.

The ESC425 contactor is a solid and reliable element of electrical installation that will meet the expectations of both professionals and end-users looking for a safe and effective solution for controlling electrical loads.
