Littelfuse® fuse reducers allow smaller size fuses to be installed into existing fuse clips to prevent overfusing.

The new Littelfuse Class T fuse blocks offer many advantages over previous generations that are noted in the features and benefits section. Of particular value is the space savings these new blocks provide.

FUSE 125V ALARM FUSE BULK H-PACK 20A. Color-coded indicator flags indicate ampere rating. Body is constructed of black polyphenylene sulfide with UL-94V0 flammability rating, contacts are of bright alloy-plated beryllium copper. Ideal for telecommunications and control panel circuits.Eliminates down time by immediately pinpointing the blown (open) circuit while triggering LED or audio alarm, while placed in mating holder (482 Series). Clear plastic lens option available for additional safety.

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.

PANELMOUNT SHKSAFE FSEHLDR 3AG FUSE LF2A. Designed to eliminate the possibility of electrical shock, as defined in IEC standards 65 and 257. Shock-Safe fuseholders feature a low profile body, fingergrip knob and anti-tease feature that eliminates circuit interruptionwhen knob is accidentally depressed.

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.

The MPS Motor Protection System monitors voltage, current, and temperature to provide a comprehensive package of 22 protective functions. The MPS is a modular system with integrated protection, motor control, metering, and data-logging functions. This system is typically used to provide protection for three-phase low- and medium-voltage, medium-to high-horsepower induction motors.

PGA-LS20 is an arc-detection, fiber-optic sensor accessory used with the PGR-8800 relay to collect light over a wide angle. This sensor weighs 1.5 kg.

PGA-LS10 is an arc-detection, optical sensor accessory used with the PGR-8800 relay to collect light over a wide angle and with high sensitivity. This sensor weighs 0.6 kg.

Littelfuse fuseblock covers protect personnel from accidentally coming into contact with energized parts. Covers are for use with various UL class fuseblocks. Please, review the ordering information for available covers.

NGR MONITOR 48-VDC ETHERNET CE. The SE-330 is an advanced ground-fault and neutral-grounding resistor monitoring relay. It measures neutral current, neutral-to ground voltage, and neutral-to-ground resistance. It provides continuous monitoring of the neutral-to-ground path to verify that the neutral-grounding resistor (NGR) is intact. This is of utmost importance—an open NGR renders current-sensing ground-fault protection inoperative and could result in a false belief that the system is functioning properly. The SE-330 can be used with low- and medium-voltage transformers and generators with low- or high-resistance grounding used in processing, manufacturing, chemical, pulp and paper, petroleum,and water-treatment facilities. For high-voltage applications, use the SE-330HV. For applications that require conformance to Australian standard AS/NZS 2081.3:2002, see the SE-330AU. The SE-330 New Revision provides these additional features: 100 trip records with date and time stamp. A mini-USB interface to view measured values, configure settings and check event records using SE-MON330 v3.2 or later. An on-board microSD card (included) can be used for long term data logging and firmware upgrades. Ground-fault trip level is adjustable from 2 to 100percent in 10 discrete settings, and in 1percent increments when using the MEM setting and SE-MON330 v3.2 or later. Dual Ethernet ports are optionally available with support for fiber and RJ45 interfaces. IEC 61850 protocol is optionally available. COMPUTER TO RELAY CONNECTION: Connect the SE-330 to the network using astandard Ethernet patch cable. Use of a crossover cable to connect the SE-330 directly to the computer running IP-Config is not recommended. A typical router will assign an IP address to all connected computers that are using DHCP. The SE-330 does not support the use of DHCP. If the SE-330 is being set-up for first time, it is recommended to only have one SE-330 connected to the network to prevent communication errors.
