ABB 1SVR450117R1200 Current Transformer - 5VA Class 1
Part Number: 1SVR450117R1200
Quick Summary
ABB CM-CT 400/1 current transformer delivers precise measurement for protection relays and metering in switchgear and motor control centers. Engineers often struggle to source a compact, reliable CT that pairs high accuracy with easy installation and scalable DIN-rail mounting. This device meets IEC/EN 61869-1 and IEC/EN 61869-2 standards alongside IEC/EN 63000 for safety declarations, and carries CE and UKCA declarations for European markets. With a small footprint of 61 mm wide, 78.5 mm high, and 48 mm deep, it minimizes panel intrusion while supporting a 400 A primary and 1 A secondary at a 5 VA burden. The included foot angle, insulating protective cap, and bar-fastening screws simplify mounting, while an optional snap-on DIN-rail accessory accelerates installation in new or retrofit builds.

FAQs
Installers benefit from the CM-CT 400/1’s plug-in design, foot angle, insulating protective cap, and bar fastening screws, which simplify orientation and secure mounting. For retrofits, the optional snap-on DIN-rail accessory reduces panel rewiring time and enables rapid integration with existing protection relays and metering modules. Ensure panel clearance and verify DIN-rail compatibility with your enclosure before mounting.
Key specs include a primary rating of 400 A, a secondary rating of 1 A, a burden of 5 VA, and accuracy class 1. Standards compliance encompasses IEC/EN 61869-1 and 61869-2, plus IEC/EN 63000 safety declarations. Dimensions are 61 mm width, 78.5 mm height, 48 mm depth, and weight around 0.27 kg, suitable for compact control panels.
Yes. The CM-CT 400/1 is designed for plug-in installation with an optional snap-on DIN-rail mounting accessory and a DIN-friendly footprint. The kit simplifies retrofits in existing MCCs and switchgear, enabling fast commissioning and reduced field wiring. Its compact size helps conserve panel space without compromising measurement accuracy or reliability.
The transformer complies with IEC/EN 61869-1 and 61869-2 for current transformers, IEC/EN 63000 for safety declarations, and carries CE and UKCA markings for European deployment. These certifications support regulatory alignment, ease procurement across regions, and help with compliance documentation during audits and OEM handovers.
The CM-CT 400/1 offers stable, accurate current measurements that improve protection settings and reduce mistripping, leading to lower maintenance costs and higher uptime.
