Overview

1SVR730850R0200 — CM-ENS.21S Liquid level monitoring relay, a level monitoring relay, liquid level monitoring, liquid level monitors from the ABB CM-ENS.21S – 24 – 240V AC/DC, dry running and overflow protection range. Listed under Liquid Level Relays on the ABB catalogue at RMS-ABB.Africa.

About 1SVR730850R0200

The CM-ENS.21S belongs to the CM liquid level monitoring relay range. It operates with a rated control supply voltage of 24 – 240 V AC/DC and has a 1 c/o (SPDT) output with contacts rated at 250 V / 4 A. It monitors liquid levels of conductive fluids and protects pumps against dry running or tanks against overflow. The working principle as well as the sensitivity can be selected via front-face potentiometers. Several electrodes and a sealable transparent cover for protection against unauthorized changes are available as accessory. The device offers screw connection technology with double-chamber cage connection terminals.
