Why Choose the ABB ESB16-02N-04 Installation Contactor?
The ABB ESB16-02N-04 is a compact 16 A installation contactor with two normally closed contacts, designed for automatic control of single-phase electrical loads in household and industrial environments. Part of the ABB ESB16..N installation contactor series, it combines dependable switching performance with a slim, modular design.
Featuring a 0NO / 2NC main contact configuration, the ESB16-02N-04 is rated for up to 16 A in AC-1 applications. Its normally closed contacts remain closed while the coil is de-energised and open when energised, making the contactor suitable for specific load-control, interlocking and automation functions.
The 110 V AC/DC rated control circuit allows operation from suitable AC or DC control supplies. ABB's ESB16..N design provides hum-free operation, low power consumption and integrated overvoltage protection, while its 18 mm width, DIN-rail mounting and screw terminals support straightforward installation in compact electrical panels.
