Why Choose the ABB ESB25-04N-01 Installation Contactor?
The ABB ESB25-04N-01 is a compact four-pole installation contactor designed for reliable control of electrical loads in residential, commercial and industrial installations. Part of ABB's ESB25..N range, it provides four normally closed (4NC) main contacts with an AC-1/AC-7a rated operating current of up to 25 A.
Designed for modular distribution boards and control panels, the ESB25-04N-01 uses a 24 V AC/DC control circuit, allowing the same contactor variant to be operated from compatible AC or DC control supplies. ABB's ESB..N design provides hum-free operation, low power consumption and integrated overvoltage protection for dependable everyday switching.
The contactor occupies just two modular spacings on a DIN rail and combines four normally closed poles in one device. This makes it particularly useful for circuits that are required to remain closed while the coil is de-energised and open when the contactor is energised.
Key Advantages
- Four normally closed (4NC) main contacts for multi-pole switching applications.
- 25 A AC-1/AC-7a rated operating current for suitable single- and three-phase loads.
- 24 V AC/DC control circuit supports both compatible AC and DC control supplies.
- ABB ESB..N technology provides hum-free operation for quieter installations.
- Integrated overvoltage protection helps protect the contactor's electronic control circuit.
- Low power consumption supports efficient control-panel and building installations.
- Compact 36 mm / two-module width for DIN rail distribution boards.
Key Features
- ABB ESB25..N installation contactor.
- Four-pole configuration.
- 0NO + 4NC main contacts.
- 25 A rated operating current for AC-1/AC-7a applications.
- 24 V AC/DC rated control circuit voltage.
- Suitable for controlling compatible single- and three-phase loads.
- Hum-free operation for noise-sensitive residential and commercial environments.
- Integrated overvoltage protection.
- DIN rail mounting with screw-terminal connections.
Quiet and Efficient 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. Unlike a latching relay, the contactor's main contacts follow the state of its control circuit, making it suitable for loads that need to be switched through thermostats, timers, relays, building-control equipment and other automatic control devices.
The ESB25-04N-01 combines a 24 V AC/DC control circuit with four normally closed contacts. With the control circuit de-energised, the NC contacts remain closed; energising the contactor causes them to open. This configuration can be useful for multi-pole control, interlocking, load-management and other applications where normally closed switching behaviour is required.
Typical Applications
- Residential and commercial electrical distribution boards.
- Building automation and load-control systems.
- Lighting, heating and compatible electrical load control.
- Multi-pole normally closed switching circuits.
- Control circuits operated by timers, thermostats or relays.
- Industrial control panels and electrical installations.
- Single- and three-phase load-control applications.
- Noise-sensitive installations requiring hum-free contactor operation.
