ABB Protecta Plus ESB25-22N-01 24V AC/DC Installation Contactor • 25 A Rated Current • 2 NO + 2 NC 4-Pole Modular Contactor • DIN Rail Mount 36 mm Width • 1SAE231111M0122

• TECHNICAL SPECIFICATIONS – 4-pole installation contactor (2 NO / 2 NC), rated current 25 A (AC-1 / AC-7a), AC-3 current 9 A / 6 A at 230 V, control voltage 24 V AC/DC, insulation voltage 500 V, impulse withstand 6 kV, DIN rail mounting, screw terminals, IP20, 36 × 85 × 65 mm.
• VERSATILE LOAD CONTROL – ABB hum-free installation contactors are available from 16 to 100 A with a wide range of main contact configurations, including NO, NC and mixed combinations. Designed for switching lighting, heating, ventilation systems, motors and pumps in residential, commercial and industrial installations.
• QUIET AC/DC OPERATION – Innovative AC/DC coil design prevents device humming and enables operation with AC or DC control voltages depending on the coil variant. The design supports quiet switching performance, making the contactors suitable for noise-sensitive environments such as hotels, offices and residential buildings.
• FLEXIBLE SYSTEM INTEGRATION – Part of the ABB installation contactor portfolio with a broad range of accessories including auxiliary contacts and protective covers. Devices allow side-by-side mounting without spacing and integrate seamlessly into ABB modular installation systems for distribution boards.
• ABB PROTECTA PLUS SYSTEM – Part of the ABB Protecta Plus modular distribution system for indoor installations, offering high internal accessibility, removable internal modules for simplified wiring, insulated neutral and earth bars, and an expandable cabinet concept for flexible electrical distribution solutions.

Important note: Please note that electrical engineering work must only be carried out by electricians or under their supervision and supervision. Please note if necessary. different country-specific standards and regulations of electrical installation and consult a local electrical installer. Devices with a connection value > 380 V/400 V require a high current connection and may only be connected by an approved electrician. For devices with a rated power > 12 kW, you need the approval of your network operator (Germany, other countries may different). Installation contactor 25 A 24 V AC/DC ESB25-22N-01 rated operating voltage 220 ... 400 V, rated operating current 25 A, use category 7, rated actuation voltage 24 ... 24 V, voltage type of operating voltage AC/DC, voltage type of actuation voltage AC/DC, number of contacts as N/O 2, number of contacts the contacts as the contacts ner 2, number of pitch units 2, installation depth 58 mm, additional devices possible, protection class (IP) IP20, 4-pin contactors ESB25..N with 36 mm width control 3-phase loads up to 25 A and are available in different contact assignments and coil voltages. They switch on electric heaters, water heaters, motors for pumps, ventilation and other drives as well as lighting. Thanks to an integrated coil circuit, they work with both AC and DC control voltages. The devices are therefore absolutely hum-free and quiet when switching. An auxiliary switch that can be attached to the left as an accessory as well as sealing caps and a spacer complete the range. ESB25..N have installation design and meet household standard EN61095, so they are particularly suitable for distribution installation.
