Why Choose the ABB ESB16-02N-03 Installation Contactor?
The ABB ESB16-02N-03 is a compact 16 A installation contactor with two normally closed contacts, designed for automatic control of single-phase electrical loads in residential, commercial and industrial installations. Part of the ABB ESB16..N installation contactor series, it combines a space-saving modular format with reliable switching performance.
Featuring a 0NO / 2NC main contact configuration, the ESB16-02N-03 is suited to applications where circuits need to remain closed while the contactor coil is de-energised and open when the coil is energised. The ESB16..N series is rated up to 16 A for AC-1/AC-7a applications and incorporates hum-free operation, low power consumption and integrated overvoltage protection.
The 48 V AC/DC rated control circuit enables operation from suitable AC or DC control supplies. With its single-module width, DIN-rail mounting and screw-terminal connections, the ESB16-02N-03 provides a practical solution for compact electrical distribution boards, automation systems and control panels.

Reliable Normally Closed Load Control
Installation contactors such as the ABB ESB16-02N-03 allow electrical loads to be controlled automatically through a separate control circuit. Its two normally closed contacts remain closed when the coil is de-energised and open when the coil is energised, providing a useful switching arrangement for selected automation, interlocking and load-management functions.
The ESB16..N range is designed for household applications as well as industrial environments and can be operated using AC or DC control voltages. Hum-free performance, low power consumption and integrated overvoltage protection help provide dependable operation in modern electrical distribution and automation systems.
Typical Applications
- Residential and commercial electrical distribution boards.
- Building automation and load-management systems.
- Lighting and electric heating control circuits.
- Normally closed automatic switching applications.
- Electrical interlocking and control systems.
- Industrial control panels and automated electrical equipment.
