For splitter applications. Both terminations must be present.

Connects the SE-601 relay to an ungrounded 24 Vdc bus.

The SE-CS30 series is a sensitive nickel-core current transformer used with Littelfuse relays to detect low levels of earth-leakage current.

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.

6 Way Transmitter. 24V DC.. The M1500 PT100 6 Way Transmitter includes six current transducers in one box for use with DIN60751 3-wire PT100 temperature sensors. The output signals from the M1500 are 4-20 mA current signals, which can be easily fed into e.g. an analogue alarm monitor such as the M3000 Analogue Alarm Monitor. Each sensor input of the M1500 can be configured for three different temperature ranges: 0-160 ºC, 0-300 ºC or 0-600 ºC.

Indicator Panel. 8 channels, 24V DC/AC. The M4600 provides flush mounted LED based indication with 6, 8 or 20 channels. Each channel can be used to indicate the state of one potential free contact. The indicator units are available with either negative or positive reference. An insert paper label provides the opportunity to print a description or instruction right next to the related channel LED. The indicator units are available for both DC of AC supply. Input signals can be +24 VDC, +48 VDC or +110 VDC.

The MPS-CTU-01-00 is a motor protection system with a supply voltage between 65–265 V ac and 80–275 V dc. This unit monitors voltage, current, and temperature with communication via RS/TIA-485.

Used as in-line protection for fluorescent fixtures, the Littelfuse LGR and LMF series fuses and LHR holder offer increased safety and reliability to lighting systems. On a 277 volt system, a fault occurring in an un-fused fixture could take out the entire branch circuit affecting up to 100 fixtures. This could cause safety problems as well as shut down operations. By individually fusing fixtures, these problems will be avoided. The added benefits of this is the ability to quickly identify the problem fixture and reduce the repair time. Fuse holders are rated up to 10 amperes at 300 volts and are equipped with 7” 18 AWG leads. Order part number LHR 000 for two leads, and part number LHR 001 for one lead and one terminal for insertion of 18 AWG ballast lead.

Perfect for use in lighting systems, this 300 VAC time delay fuse is designed to handle ballast transformer in-rush currents.

KLDR020 is a Class CC fuse with an ampere rating of 20.

Littelfuse LLNRK and LLSRK series POWR-PRO™ fuses provide superior overload and short circuit protection for service entrance, main, feeder and general-purpose branch circuits up to 600 amperes. LLNRK/LLSRK series fuses can be installed in existing Class H fuse blocks to upgrade systems containing lower interrupting rating Class H one-time or renewable fuses.

RK1 fuses are extremely current-limiting fuses meaning they greatly reduce or eliminate damage to circuits and equipment under short-circuit conditions. Replacing existing Class H, K and RK5 fuses with RK1 fuses is one of the easiest ways to immediately improve the protection of plant workers and equipment.
