1SAE231111R0222 ABB ESB25-22N-02 Installation Contactor 2NO/2NC 25 A 42 V AC/DC

Why Choose the ABB ESB25-22N-02 Installation Contactor?

The ABB ESB25-22N-02 is a compact four-pole installation contactor designed for reliable electrical load control in residential, commercial and industrial installations. Part of ABB's ESB25..N range, it combines two normally open and two normally closed main contacts (2NO + 2NC) with a rated operating current of up to 25 A for AC-1 applications.

Designed for modular distribution boards and control panels, the ESB25-22N-02 uses a 42 V AC/DC control circuit, allowing operation from compatible AC or DC control supplies. ABB's ESB..N technology provides hum-free operation, low power consumption and integrated overvoltage protection for dependable automatic switching.

The balanced 2NO + 2NC contact arrangement provides both make and break switching functions from a single device. With a compact 36 mm two-module width and DIN rail mounting, the ESB25-22N-02 is well suited to coordinated load control, interlocking and automation applications where normally open and normally closed circuits need to operate together.

Key Advantages

• 2NO + 2NC main contact configuration for versatile mixed switching requirements.
• 25 A AC-1 rated operating current on both NO and NC contacts.

Flexible 42 V AC/DC Mixed-Contact Load Control

ABB ESB25..N installation contactors are designed for electrically controlled switching of single- and three-phase loads in household, commercial and industrial environments. Their AC/DC-operated control circuits allow straightforward integration with compatible timers, thermostats, relays, switches, programmable controllers and building-automation equipment.

The ESB25-22N-02 combines a 42 V AC/DC control circuit with two normally open and two normally closed contacts. When the contactor is energised, the two NO contacts close while the two NC contacts open. This balanced contact arrangement makes the device particularly useful for coordinated switching, interlocking, change-of-state signalling and other applications requiring simultaneous NO and NC functions.

Typical Applications

• Residential and commercial electrical distribution boards.
• Building automation and load-control systems.
• Lighting and heating control circuits.
• Mixed normally open and normally closed switching functions.
• Electrical interlocking and signalling circuits.
• Control circuits operated by timers, thermostats or relays.
• Industrial control panels and electrical installations.
• Compatible single- and three-phase load-control applications.
