Protective Relay Replacement
Protective Relay Replacement
(OP)
I have an application for a microprocessor relay to replace an existing ABB (I-T-E) CircuitShield analog solid-state overcurrent relay. But the owner wants something that will fit in the same cutout. I haven't been able to find anything that wouldn't require some cutting.
The existing cutout is about 3.75 inches tall and 6.63 inches wide. The Basler BE1-851 is close, but would require a wider cutout. Same with the SEL-501.
Any other suggestions for a utility-grade digital overcurrent relay that would fit this opening?

These are three-phase relays. I already recommended the H1 case option as the best alternative, but I'm getting some push back from them due to the panel cutting required, so I wanted to double-check to see if I was overlooking some other option.
Thanks.

There are not as many of these out there as IAC and CO relays, but maybe enough that someone should think about offering a replacement in a similar form factor.
Of course, ABB still sells new CircuitShield relays (along with the CO relays).
