- AA suffix: 50 Hz with 80 to 265 V AC/DC auxiliary supply
- RS 641 014-AA with a make-type normally open trip contact
- SPA serial communication and IP54 front protection when correctly panel mounted
The SPAM150C SPAM150C-AA suffix identifies the circuit-breaker-drive version of the SPAM 150 C motor protection relay.
Its protection functions include thermal overload, high-set overcurrent, phase unbalance, phase sequence, earth fault, undercurrent and start supervision.
Before replacement, preserve relay settings, current-transformer ratios, trip logic, SPA communication parameters and the exact AA auxiliary-supply configuration.
Availability, condition, price, and shipping time for SPAM150C SPAM150C-AA are confirmed during quotation.
