ER-15KV is a sensing resistor accessory used on systems up to 15 kV (non-continuous duty). It is an accessory for SE-330, SE-325, and SE-330AU.

Motorized Potentiometer 24VDC, 0.8-6 rpm. The E7800 Motorized Potentiometer is typically used as an interface between increase/decrease relay contacts (or push buttons) and a device requiring control by an external potentiometer (e.g. the speed trim of an electronic governor). All three wires of the potentiometer are directly accessible on external connection terminals, thus providing the best possible flexibility for almost any application. A special version of the E7800 with DC voltage output is also available. The DC output voltage follows the position of the potentiometer. The design of the E7800 ensures that the potentiometer will “remember” its position although supply is lost

The SE-CS10 series current transformers (CTs) are key components of the Littelfuse protection relay product line. Littelfuse SE-134C and SE-135 Ground-Fault Ground-Check Monitors are designed specifically for use with the SE-CS10 CTs. A Littelfuse SE-330 Neutral-Grounding-Resistor Monitor and a Littelfuse SE-701 Ground-Fault Monitor can also be equipped with the SE-CS10 series to achieve the desired ground-fault-trip settings. Littelfuse motor- and feeder-protection relays can also make use of the SE-CS10 series either to measure phase current or ground-fault current.

SE-325T is a neutral-grounding resistor monitor with a supply voltage of 120 ac and a ground-fault trip level of 0.5–4.0 A.

SE-325SN is a neutral-grounding resistor monitor with a supply voltage of 120 ac and a ground-fault trip level of 0.5–4.0 A.

PGR-4300-120 is a generator ground-fault relay with a supply voltage ac of 120.

Panel-mounted analog am meter displays the Ground-Fault Current as a percentage of the set-point.
