The ABB CT‑ERS.22 is a compact, single‑function electronic ON‑delay timer relay. When control supply voltage is applied, the relay waits for a user‑selected delay time, then changes its output contacts from their default state. Its slim 22.5 mm width and DIN‑rail mountable housing make it suitable for installation in control panels, automation cabinets, and other industrial or commercial electrical control systems. The relay supports a wide supply‑voltage range, accommodates many delay‑time settings, and uses SPDT (change‑over) contacts to control downstream loads or contactors, making it a versatile timing device for automation, motor control, lighting, sequential logic, and general‑purpose time‑delay applications.

The ABB CT‑ERS.22S is a single‑function electronic ON‑delay (delay‑on‑make) timer relay from ABB’s CT‑S timer family. It provides delayed switching functionality: when control power is applied, it waits for a preset delay period, then activates its output contacts. With adjustable time ranging from very short to very long (0.05 second up to 300 hours), the CT‑ERS.22S is suitable for many timing applications in automation, motor control, lighting control, delay‑on‑start, sequential control circuits, or machine control panels. It is compact, DIN‑rail mountable, with a slim 22.5 mm width — making it easy to integrate into control cabinets and distribution panels. The relay includes 2 change‑over (SPDT) contacts, so it can drive loads (directly within rating) or control contactors/other devices following the time delay.

The ABB CT‑ARE is a compact, single‑function electronic time relay from ABB’s CT‑E timer range. It provides a true OFF‑delay (delay‑on‑break) function: when the control supply voltage is removed, the relay keeps its output energized for a preset delay time, then de‑energizes. It does not require a separate auxiliary supply — timing works directly based on the control supply voltage applied to its input. With simple adjustment of the delay time via a thumbwheel, and a straightforward 1 change‑over (SPDT) output, CT‑ARE is designed for cost‑efficient, reliable timing tasks in control panels, automation systems, motor control, lighting control, or sequential switching circuits. The device is slim (22.5 mm wide), DIN‑rail mountable, and features a front‑panel LED to indicate supply status.

The ABB CT‑SDE 1SVR550217R4100 is a single‑function electronic time‑relay belonging to ABB’s “CT‑E” timer family. It is designed to provide a star‑delta (star‑triangle) time‑delay function — typically used for motor starting circuits that need to begin in “star” configuration, then automatically switch to “delta” after a preset time. The relay allows a delayed change‑over when starting motors, which reduces the starting current and mechanical stress. It is compact, DIN‑rail mountable, and uses screw‑terminal connections. The device offers a small mechanical footprint, making it suitable for control panels, motor control centers (MCC), automation cabinets, or motor‑starter assemblies

ABB CM‑ESS.MS 1SVR730830R0500 is a compact, single‑phase voltage monitoring relay designed to monitor AC or DC supply voltage and to detect over‑voltage or under‑voltage conditions. It is part of ABB’s “CM” series of single‑phase monitors. The device provides a 2 change‑over (SPDT) contact output that can be used to control alarms, contactors or protective circuits when the monitored voltage goes outside the pre‑set threshold.

The ABB CM‑MPS.41S is a three‑phase monitoring relay designed to continuously monitor three‑phase supplies for proper phase conditions — including phase presence (no phase loss), correct phase sequence (phase rotation), voltage level (over‑/under‑voltage), and phase balance (detecting unbalance). It ensures that motors and other three‑phase equipment are protected against supply anomalies which could damage equipment or lead to malfunction.

The ABB 1SVR730010R0200 is a multifunction electronic time relay (CT‑MFS.21S) designed to provide a wide range of timing functions for industrial and automation control applications. It supports multiple timing modes, including ON‑delay, OFF‑delay, pulse/impulse, flasher, and star‑delta changeover. The relay offers dual SPDT (2 c/o) outputs, with one output optionally usable as an instantaneous contact for flexible control logic. It accepts a wide control supply voltage range (24–240 V AC or DC) and is DIN‑rail mountable with screw-terminal connections. The device can optionally connect to a remote potentiometer for fine adjustment of time delay.

The ABB 1SVR730885R3300 is a compact three-phase monitoring relay designed to monitor a three-phase supply (L1-L2-L3, optionally with neutral) for supply integrity and safety. It detects phase failure (loss of a phase), phase sequence (correct order), phase unbalance, over-voltage, under-voltage, and interrupted neutral. When any monitored parameter goes outside preset limits, the relay triggers its output contacts. Adjustable trip delay and selectable ON or OFF delay prevent nuisance trips due to transient conditions or startup surges. The device is DIN-rail mountable with screw-terminal connections, suitable for control panels, switchgear, motor control centers, and industrial or commercial installations.

The ABB 1SVR730794R1300 is a three‑phase monitoring relay from ABB’s “CM‑PVS.31S” series. It is designed to monitor three‑phase power supply (L1‑L2‑L3) for correct phase sequence, phase presence (no phase loss), and over‑/under‑voltage. If a phase failure, wrong phase order (phase rotation), undervoltage or overvoltage is detected (and thresholds are exceeded), the relay trips — opening its output contacts to protect motors or loads. The device supports adjustable trip delays and optional on‑ or off‑delay operation, to avoid nuisance trips during supply transients. It is compact, DIN‑rail mountable, with screw‑terminal connections, making it suitable for control panels, motor control centers (MCC), switchgear or industrial/commercial installations needing phase‑failure protection.

The ABB 1SVR730794R3300 (also known as CM‑PVS.41S) is a three‑phase monitoring relay designed to monitor supply for correct phase sequence, phase presence, and over‑/under‑voltage conditions. It continuously checks a three‑phase supply (L1‑L2‑L3) and will trigger its output contacts if a phase failure, phase reversal, undervoltage or overvoltage is detected, optionally after an adjustable delay. The relay is DIN‑rail mountable, compact (22.5 mm width), and suited for control panels, motor control centers (MCCs), switchgear, or other installations where supply‑phase integrity is critical. It's typically used to protect three‑phase motors, compressors, pumps or sensitive equipment from unsafe supply conditions.
