SE-330-00-01 is an advanced ground-fault and neutral-grounding resistor monitor with a supply voltage ac of 65–265 and a supply voltage dc of 85–275. Network communications is offered via USB.

RELAY ELEC GF/GC - NGR SHOCK MOUNT KIT. RELAY ELEC GROUND FAULT/GROUND CHECK - NGR SHOCK MOUNT KIT.

The MPS-CTU-02-00 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 - DeviceNet.

Indicator Panel. 8 channels, 110V 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.

Engine Controller. The M2000 Engine Controller will control and protect any industrial combustion engine, which accepts discreet I/O signals for control of the crank, the fuel valve and the stop solonoid (if applicable). The engine must be able to supply potential free contacts for starter disengagement and over speed alarm (normally done through a standard tacho relay). The M2000 is typically used as an engine controller for diesel or gas driven generator sets. The operator can start the engine either by pressing a button on the front facia, or by providing and external start signal through a potential free contact (e.g. a relay). The M2000 can be configured to perform multiple start attempts. The M2000 detects a successful start from the crank disconnect signal provided by the tacho relay (normally at 33percent of nominal speed). The M2000 will operate the fuel valve as well as a start warning signal shortly before cranking the engine. The progress of the start sequence is clearly indicated on the front facia LEDs.

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

Analog Alarm Annunciator 30. The M3000 is a compact 24 channel Analogue Alarm Annunciator. The M3000 is ideal for surveillance of temperature sensors, pressure sensors and any other kind of sensors providing a signal within the range of 0-20 mA, 0-10 VDC or 0-30 VDC. A linearly pre-scaling is done in order to convert the measured input voltage or current into the entity measured by the sensor (e.g. temperature or pressure). Once this conversion has taken place, all further references are made to the measured entity.

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

Engine Controller 120. The M2000 Engine Controller will control and protect any industrial combustion engine, which accepts discreet I/O signals for control of the crank, the fuel valve and the stop solonoid (if applicable).

The SE-CS10 series is a current transformer used with Littelfuse relays to detect earth leakage current.

SE-325SNT 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.

UL CLASS T FAST ACTING T-PACK 3A. Space-saving Class T fuses are the most compact fuses available in ratings above 30 amperes — less than one-third the size of comparable Class R fuses. When rated in accordance with the NEC, Class T fuses provide fast-acting overload and short circuit protection for non-inductive circuits and equipment. Used in inductive circuits, the ampere rating of Class T fuses must be increased to prevent opening on inrush currents. In such instances, Class T fuses may provide only short circuit protection.For motor and general purpose circuits where space is not critical, we recommend POWR-PRO™ JTD_ID Indicator series, LLNRK/LLSRK series, or FLSR_ID Indicator series. Applications: Protection of individual electric services and meters. Main switches containing Class T fuses may be used to provide compact protection for meter stacks. Molded case circuit breaker load centers and panelboards have increased interrupting ratings when “series rated” with Littelfuse Class T fuses. Refer to panelboard manufacturers’ literature for UL Listed combination of fuses and panelboards. Series ratings up to 200,000 amperes are available. Space Saving: Typical three-pole Class T fuse blocks require less than 50percent of the panel area required for Class R fuse blocks. Switch enclosures, fuse pullouts, and other equipment using Class T fuses are often correspondingly more compact. Safety: 200,000 A.I.R. — Reliable interruption of all overcurrents up to 200,000 amperes. Extremely current limiting — Stops damaging short circuit current faster than any mechanical protective device. Fast-Acting — Provides fast-acting overload protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components. Longer Equipment Life: Current limiting design greatly reduces damage to equipment caused by heating and magnetic effects of short circuit currents. Economical: Extremely current limiting design often permits use of readily available, less costly equipment. Used as input or output fuses for surge-sensitive components, such as variable speed drives and rectifiers, fast-acting Class T JLLS fuses may prevent opening of expensive semiconductor fuses protecting individual components.
