ABB CM-SRS.22S

ABB Stotz S&J Current Monitoring Relay CM-SRS.22S Manufacturer: ABB Stotz S&J Description: Current Monitoring Relay 2We 0.3-15A Type: CM-SRS.22S Electrical connection type: Screw connection Removable terminals: no 1-phase undercurrent possible: yes 3-phase undercurrent possible: no 1-phase overcurrent possible: yes 3-phase overcurrent possible: no 1-phase window possible: yes 3-phase window possible: no Includes DC undercurrent function: yes Includes DC overcurrent function: yes DC window function: yes Rated control supply voltage Us at AC 50 Hz: 220..240 V Rated control supply voltage Us at AC 60 Hz: 220..240 V Voltage type for actuation: AC Current measurement range: 0.3..15 A Min. adjustable response delay time: 0 s Max. allowable response delay time: 0 s Min. adjustable fallback delay time: 0.1 s Max. allowable fallback delay time: 30 s Number of contacts as changeover: 2 External current transformer: no Width: 22.5 mm Height: 85.6 mm Depth: 103.7 mm The current monitoring relays of the CM series protect single-phase networks (DC or AC) from overcurrents and undercurrents between 3 mA and 15 A. Devices with a maximum measurement range of 1 A are available in two different connection versions. You can choose between the proven screw connection technology (double-chamber box connection terminals) and the tool-free Easy Connect connection technology (push-in terminals). Devices with a measurement range of up to 15 A are available with screw connection technology.
