Description
0SPF xxxx H XR
The SPF Solar Protection Fuse series has been specifically
designed for the protection of photovoltaic (PV) systems. This
family of midget-style fuses (10 x 38 mm) can safely protect PV
modules and conductors from reverse-overcurrent conditions.
As PV systems have grown in size, so have the corresponding
voltage requirements. This increase in system voltage has
typically been intended to minimize power loss associated with
long conductor runs. Standard circuit protection devices are not
designed to completely protect photovoltaic panels. However,
the SPF series is UL Listed to safely interrupt faulted circuits up
to this demanding voltage level.

A key objective for panel designers is safe distribution
of power to multiple fuse holders in a compact design.
The Littelfuse UL 508 Listed bus bar system eliminates
most wire terminations in a timesaving package. A power

POWR-BLOKS
Distribution Blocks • Splicer Blocks • Covers
Connectors
Box lug connectors are designed for use with a single or
multiple, solid or class B or C stranded conductor. For UL
approved use of more than one conductor per connector
opening, contact Littelfuse Technical Service. Manufacturers of
cable terminations can furnish crimp-on sleeves for fine stranded
conductors which permit these conductors to be used with box
lugs.
Ampere Ratings
The ampere rating per pole for power distribution blocks is
based on the line ampacity of 75 °C insulated conductors per
NEC* Table 310.16. If 60 °C insulated conductors are used,
load must not exceed the ampacity of 60 °C conductors. Use of
conductors rated in excess of 75 °C is permitted (for example
90 °C), however, load must not exceed the ampacity of 75 °C
conductors.
Description
POWR-BLOKS power distribution blocks offer a safe,
convenient way of splicing cables, providing a fixed junction
tap-off point or splitting primary power into secondary circuits.
Lx2xxx-DIN series offers integral DIN-rail mount and an
optional hinged safety cover.
Optional power distribution block covers provide protection
against accidental shorting between poles caused by loose
wires, tools, or other conductive material. They also protect
personnel from accidentally contacting energized connectors.
Applications
Typical applications include heating, air conditioning and
refrigeration systems, elevator systems, material handling
equipment, control panels, motor controls, switchgear, and
anywhere power needs to be distributed to more than one
load.

TVS (TRANSIENT VOLTAGE SUPPRESSION) DIODES
What Are Voltage Transients?
TVS and Solar Inverter Protection
Voltage transients are unwanted short duration surges of electrical
energy. They may result from the sudden release of previously
stored energy, and can come from internal and external sources.
If the voltage magnitude of the transient is large enough, circuit
component damage or malfunction of the circuit may result.
Integration of Transient Voltage Suppression (TVS) components
within solar system designs help to prevent the damaging effects
of transient events and assure compliance to safety and reliability
standards. Solar power inverters are vulnerable to transient voltage
effects and its direct connection to other system components allows
transient voltage transfer. For example:
Transients can occur either repeatedly or as random impulses.
Repeatable transients are frequently caused by the operation of
other system components, such as motors, generators or the
switching of reactive circuit components. Random transients, are
often caused by lightning, electrostatic discharge (ESD), and other
outdoor environment events.

Lightning-induced transient events may pass through the solar
array and outdoor cabling to the inverter
Transients originating from the outside utility power grid may
pass through the main circuit panel and cabling to the inverter
Startup of motorized equipment enables vulnerabilities
produced by repeated load changes
Electrostatic discharge events generated internally and
externally to the system may pass between the inverter and
sensitive electronic control equipment
It is important to build surge protection in the inverter and at other
locations before damaging transients may reach sensitive equipment.

TVS Diodes are used to protect semiconductor components from high-voltage transients. Their p-n junctions have a larger cross-sectional area
than those of a normal diode, allowing them to conduct large currents to ground without sustaining damage. Littelfuse supplies TVS Diodes with
peak power ratings from 200 W to 30 kW, and reverse standoff voltages from 5 V to 512 V. For more information visit Littelfuse.com/tvsdiodes

SE-601 SERIES (PGR-2601)
Dc Ground-Fault Monitor
Description
The SE-601 is a microprocessor-based ground-fault relay for
ungrounded dc systems. It provides sensitive ground-fault
protection without the problems associated with nuisance
tripping. Ground-fault current is sensed using an SE-GRM
Series Ground-Reference Module—a resistor network that
limits ground-fault current to 25 mA. The SE-601 is used
on ungrounded dc systems ranging from industrial 24 V dc
control circuits to 1000 V dc solar and transportation systems.

delayed response
Form A and Form B output contacts for operation of
separate annunciation and trip circuits
Provides means for connecting to a meter
(PGA-0500) or a control system
Retains trip state when de-energized to simplify
troubleshooting
Selectable fail-safe or non-fail-safe operating
modes allow connection to shunt or undervoltage

EL731 SERIES
Ac/Dc Sensitive Earth-Leakage Relay
Description
The EL731 is a microprocessor-based ac/dc Sensitive
Earth-Leakage Relay that offers complete coverage for all
frequencies from 0 to 6,000 Hz. Two CTs are required for
the entire frequency range, or one CT can be used for only
low- or high-frequency detection. An RTD/PTC sensor input
allows over-temperature protection for a motor or drive. The
EL731 offers metering, password-protected alarm and trip
settings and optional network communications. It is primarily
used to add low-level ground-fault protection to variablespeed drives, and to dc circuits.
