Technical service profile for ABB CR-M220DC4L 1SVR405613R9100

ABB CR-M220DC4L 1SVR405613R9100 should be specified as a complete device, not inferred from a similar family name. Its protection, control or measurement role must match the actual equipment and installation.

Technical data for model selection

The stated CR-M220DC4L 1SVR405613R9100 data identify the selected reference and its engineering boundaries. Confirm the unit label, applicable standard and exact options before ordering or energizing.

What must match

Check CR-M220DC4L 1SVR405613R9100 against socket, coil polarity, contact load, wiring and test-button policy. In procurement, ask for photographs or ABB documentation that show the complete designation and terminal configuration.

If the candidate CR-M220DC4L 1SVR405613R9100 differs from the installed device, document the difference and obtain an engineering decision before fitment.

Design intent

The intended duty of CR-M220DC4L 1SVR405613R9100 is to isolate and repeat the specified control signal. Mark the circuit, asset or process tag and preserve the plant drawing that governs this function.

Do not assume a different suffix within CR-M220DC4L provides the same duty as CR-M220DC4L 1SVR405613R9100; ratings and accessory arrangements can differ.

Installation controls

Before working on CR-M220DC4L 1SVR405613R9100, apply the approved isolation and permit controls. Capture the existing connections, settings and safety functions as a recoverable baseline.

Install CR-M220DC4L 1SVR405613R9100 with the correct conductor, panel spacing and environmental protection. Follow the ABB instructions for the specific construction rather than using a generic wiring assumption.

Handover evidence

For CR-M220DC4L 1SVR405613R9100, check pickup, release, LED and all four contact sets. Record the measured result, witness and date beside the equipment tag.

Retain the final CR-M220DC4L 1SVR405613R9100 designation, revision, settings and test outcome in the maintenance record so later work does not rely on memory.

Fault-finding baseline

For a future fault involving CR-M220DC4L 1SVR405613R9100, keep records of upstream supply, load, trip or output state and connected accessories. This separates a device issue from a wiring or process issue.

A replacement CR-M220DC4L 1SVR405613R9100 should be checked at the same duty point as the prior installation, with abnormal behavior investigated before return to service.
