ABB SPAM150C is a SPAM 150 C current measuring multi-function relay documented for the applicable ABB system configuration. Its recorded specification includes product type relay, rated phase current Adjustable to 1A or 5A, rated zero-sequence current Adjustable to 1A or 5A. Correct selection depends on the complete article identity, installed equipment, mechanical or electrical interfaces and the documented configuration rather than appearance alone. Using the exact model helps maintenance teams avoid incompatible revisions, connector arrangements and application variants.
Before installing SPAM150C, record the original nameplate, installed position, connected assemblies and every relevant configuration detail. Compare the supplied unit with the existing hardware and applicable ABB service documentation, isolate all affected energy sources and preserve required settings or calibration data. After installation, inspect each affected interface and complete controlled functional checks before returning the equipment to service.
The SPAM150C ABB SPAM 150 C current measuring multi-function relay is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.
ABB SPAM150C documentation and reference links.
Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
ABB documents thermal overload, high-set overcurrent, earth-fault, phase-unbalance, phase-sequence, undercurrent and motor-start supervision functions. Apply only to the complete SPAM150C identity.
Before connection, match 1 A or 5 A phase and earth-current inputs, the selected auxiliary-supply module, trip contact and SPA bus interface.
Document the installed state, then secondary-injection test every enabled stage, trip path, alarm and restart inhibit.
