ABB 7TBA050280R0027 Meter Socket Transformer - CSA 27716
Part Number: 7TBA050280R0027
Quick Summary
ABB 7TBA050280R0027 meter socket transformer delivers unwired power conversion for underground service applications. Engineers confront field wiring complexity and limited test options, which can slow installation and increase risk. This unit is certified to CSA 27716 for underground equipment and safety compliance, supporting reliable Canadian and North American deployments. With a 20 A current rating and 600 V rating, it meets common underground service specs, while its compact footprint—19-1/8 in high, 11-13/16 in wide—facilitates installation in tight spaces. The combination of test-switch provision, unwired design, and standard 13 jaw enhances service-utility readiness, while the Microlectric branding signals robust, field-proven performance for meter sockets and related power distribution components.

FAQs
Is this meter socket transformer compatible with standard underground service panels and meter sockets? It is a 1‑phase, unwired unit rated at 20 A and 600 V with a 13 jaw connection, designed to mount with conventional meter sockets. The product origin is Canada, and it carries CSA 27716 compliance to support safe, code-aligned installations in North American underground applications.
Core specs include 20 A current rating, 600 V voltage rating, and single-phase operation. The unit features an unwired configuration and a test switch provision, plus a 13 jaw design for secure conductor connections. These details translate to predictable load handling, straightforward testing, and reliable integration with typical underground service feeders.
Yes. The unit is explicitly designed for underground service applications, indicated by its CSA 27716 standard and the 'For underground service only' designation. Its unwired design and test switch provision minimize field wiring work, while its compact footprint facilitates installation in buried or recessed service environments.
The primary standard is CSA 27716, ensuring safety and suitability for underground meter/socket equipment in Canada and the U.S. This certification supports regulatory compliance during procurement and field installation, reducing risk during inspections and aligning with utility requirements for underground power distribution.
Maintenance is minimal due to the unwired design, reducing on-site wiring tasks and potential mis-terminations. The built‑in test switch aids commissioning checks, lowering startup time. Over the project lifecycle, this translates to lower labor costs, faster deployment, and improved system reliability in underground service environments.
