Why Choose the ABB ESB25-40N-01 Installation Contactor?
The ABB ESB25-40N-01 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 provides four normally open main contacts (4NO) with a rated operating current of up to 25 A for AC-1 applications.
Designed for modular distribution boards and control panels, the ESB25-40N-01 uses a 24 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 4NO configuration enables four normally open switching paths to operate together from a single control signal. With a compact 36 mm two-module width and DIN rail mounting, the ESB25-40N-01 provides efficient four-pole load control while conserving valuable panel space.

Efficient Four-Pole 24 V AC/DC 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 circuit allows straightforward integration with compatible timers, thermostats, relays, switches and building-automation equipment.
The ESB25-40N-01 combines a 24 V AC/DC control circuit with four normally open contacts. When the contactor is energised, all four NO contacts close together, allowing multiple poles or circuits to be controlled simultaneously. This makes the device particularly suitable for coordinated lighting, heating, motor and general load-control applications.
Typical Applications
- Residential and commercial electrical distribution boards.
- Building automation and load-control systems.
- Lighting and heating control circuits.
- Four-pole normally open switching applications.
- Control circuits operated by timers, thermostats or relays.
- Industrial control panels and electrical installations.
- Compatible single- and three-phase load-control applications.
- Noise-sensitive installations requiring hum-free contactor operation.
