What stands out about this unit is that it carries the trusted name of Deltrol.
Siemens 3RU1116-1KB0 Overload Relay AC15 24V 4/3A 230V 3/2A 400V 1.5/1A IP20
This general purpose relay carries the Brown Boveri Electric Inc. brand, which I personally for steady performance.
A nice touch here is the RIB brand on the relay, giving it a familiar look for electricians.
