Product Overview
The ABB ESB20‑11N‑06 belongs to ESB‑series modular installation contactor, with 1 normally‑open plus 1 normally‑closed main contacts. The special silent coil supports both AC230V and DC230V control signals, eliminating operating hum noise. It is used for remote switching of single‑phase lighting, heating, ventilation and non‑motor loads inside distribution cabinets. It solves typical pain‑points: local manual switching limitation, audible hum of conventional AC‑coil contactors, requirement for both AC and DC control input. Panel builders and maintenance technicians benefit from ultra‑narrow 1‑module footprint, DIN‑rail clip‑on mounting and drop‑in spare‑part replacement for existing ESB‑series installationsABB Group.
Application Scenarios
- Building automation distribution cabinet: Remote ON/OFF control for large‑scale lighting, fan coil units, electric‑heating loads in office, hotel and commercial buildings.
- HVAC auxiliary control cabinet: Switch ventilation fan, circulating pump single‑phase load controlled by PLC or building BMS signal.
- Machine‑tool auxiliary single‑phase circuit: Remote switching for cabinet lighting, socket power supply.
- Legacy low‑voltage cabinet retrofit & spare replacement: Direct DIN‑rail drop‑in replacement for old ESB‑series contactors.
