BENEDIKT & JAGER U12 16A4 RELAY 2.7-4A NSMP Relay

BENEDIKT & JAGER U12/16A-4 is a three-pole thermal overload relay in the U12/16 family, designed to protect three‑phase motors by monitoring line current in a 2.7–4 A range and triggering a trip when the load exceeds the limit. This model, sometimes listed as U12/16A-4 or U12/16A4 in catalogs, is offered in an auto‑reset variant and supports voltages up to 600 VAC. The unit weighs about 0.22 lb and is associated with Benedikt & Jager's K1 series of overload relays; it is intended for use with Benedikt/Jager U12 contactors, matching the 3‑pole protection scheme. In official catalogs, the U12/16E 4 designation corresponds to the 2.7–4 A class within the U12/16 family, confirming the model lineage. Typical applications include motor protection within 3‑phase control circuits in industrial equipment, where the relay acts as a protective device to interrupt current if the motor draws excessive current, reducing risk of overheating and damage.
