SE-330HV-03-00 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. This monitor is used for high-voltage applications. Network communications is offered via USB; Ethernet (Dual RJ45).

Alarm Annunciator12-24V DCIP54. The M1000 is an Alarm Monitor capable of surveying the state of up to 10 potential free contacts. The inputs of the M1000 can be used to monitor both normally open (NO) and normally closed (NC) contacts. Each contact can be sourced to a positive or negative reference. The M1000 includes a total of 10 inputs. Each input controls two bright red LEDs and an open collector output. A built-in relay provides audible alarm through control of an external siren. The first incoming alarm is indicated with a quick flashing light, following alarms are indicated with slow flashing light. LEDs will keep flashing until the alarms are acknowledged, even though the input signal has been deactivated. Pressing the RESET pushbutton will acknowledge all new alarms whereby all flashing LEDs will change to steady light, provided that the related inputs are still active. Pressing the RESET push button will also silence the siren. The reset sequence is programmable.

For use with Littelfuse FLNR_ID/FLSR_ID, IDSR, LLNRK/LLSRK and KLNR/KLSR series fuses.

POWR-SPEED SQB SIZE 1XL BOLTED BL 315A. Littelfuse PSX series 1500 V dc high-speed square bodyfuses are specially designed to protect battery energy storage systems (BESS), photovoltaic inverters, and many of dc applications such as dc common bus systems, larger industrial regenerative drives, rectifiers and, metal processing equipment. The PSX series fuses are extremely fast-acting, offering high-speed performance up to 1500 V dc, ranging from 80 A to 1400 A in the smallest NH XL package sizes. The PSX series is available with multiple mounting terminations including flush-end style, DIN-style and bolted-blade style. Visual blown fuse indication is standard on all fuses and optional micro-switch is available for external indication. PSX series are certified to UL 248-13 and designed to meet EN high-speed semiconductor fuse standard and IEC 60269-7, a new battery protection fuse standard in development.

All Littelfuse Class G fuse blocks offer snap-to-release DIN rail mounting and universal mounting holes. Class G fuse blocks are designed for use with time-delay current limiting Class G fuses.

ER-72KV is a sensing resistor accessory used on systems up to 72 kV (non-continuous duty) to monitor the continuity of a neutral-grounding resistor. It is an accessory for SE-330HV.

FLSR020ID is a Class RK5 fuse with an ampere rating of 20 and cartridge-style construction.

1POLE INLINE FUSEHLDR W/COPPER SET SCR. The Littelfuse 600 V in-line watertight fuse holders are the ideal answer for all high humidity and corrosive environments where fuses are required. Available in both breakaway and non-breakaway, single and double pole versions, these fuse holders allow maximum flexibility for any application. Applications: Street, alley, and parking lot lighting. Security and perimeter lighting. Traffic signals. Outdoor illuminated signs. Sports lighting. Boat electrical circuits. Tractors and yard equipment. General outdoor circuit protection. Benefits: Safety-Permits individual fixture or device to be disconnected from circuit for servicing. Eliminates possibility of shock. Individual fixture fusing-Prevents loss of one fixture through accident, vandalism, or end of life from darkening the entire circuit. Simplifies maintenance- Being able to immediately identify the one faulted fixture eliminates testing the entire circuit, speeds repair and permits servicing the individual unit while the rest of the circuit is functioning. Reduces damage from fault-Can prevent faulted ballast or other failure from severely damaging fixture or device, reducing necessary repair or need of replacement. Features: Watertight-Internal O-ring provides watertight seal. Superior terminal seeds-Ultrasonically-welded terminals provide maximum strength and eliminate leaking at terminals. Break-Resistant- Fiberglass –reinforced polymer body resists damage from dropping or impact much better than phenolic look-alikes. Flexible terminations-Accommodates a wide range of stranded or solid copper conductors, with either crimp or screw terminals. One-pole and two-pole models- available to accommodate all system voltages up to 600v.

Surge protection devices (SPDs) provide equipment protection from transient overvoltage events lasting micro-seconds. By limiting the overvoltage to the equipment during these events, costly damage and downtime can be mitigated. The surge protection devices for the 1+0 configuration are available for 60 V to 600 V nominal voltage sub-distribution board applications.

Motorized Potentiometer24V DC,1turn 5k. 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
