Sold as is. No warranty from the Seller. No Returns.
SKU: NC016
CONDITION: Used in excellent, very clean cosmetic condition and appears lightly used or possibly installed only briefly. The housing, front face, terminal areas, labels and DIN-rail mount show minor handling/storage marks, light dust and small surface scuffs, but no obvious cracks, burns, melted areas or major damage. No original box is included. Operational testing has not been confirmed, so it is being sold as shown and as is. See all detailed pictures and read the full detailed description provided by the seller to know what you are purchasing.

Manufacturer Background
General Electric's Industrial Solutions business supplied electrical-distribution, protection, motor-control and industrial-control products, including the C-2000 contactor and RL control-relay families. ABB acquired GE Industrial Solutions on June 30, 2018, integrating the business into ABB's electrification operations while retaining access to the GE-branded installed-product base.
Country of Manufacture: Italy
This is directly confirmed by the “MADE IN ITALY” marking visible on your relay.
Release Date / Age
The GE C-2000 RL4 control-relay family was documented in GE's 1999 product literature, including the RL4RD031T 3NO/1NC DC-operated configuration. It continued appearing in later GE catalogs, including a 2010 control catalog.
