Any listing in this product directory or other related materials, where “NRTL” appears next to the product name was tested and is listed by ARL as an NRTL, consistent with the requirements of the NRTL Directive.  Other products are listed solely by ARL under its accreditation to ISO 17025 and ISO 17026.


The products listed here include energy management equipment and associated sensing devices rated 600 volts or less and intended for installation in accordance with the National Electrical Code, ANSI/NFPA 70.

This equipment energizes or de-energizes electrical loads to achieve a desired use of electrical power and may incorporate devices for watt-hour meter switching in load management applications.  The equipment is intended to control electrical loads by responding to sensors or transducers monitoring power consumption, by sequencing, by cycling the loads through the use of preprogrammed data logic circuits or any combination thereof.  Devices responding to signals from a utility company may receive the signals over the power lines or as radio signals.

Requirements for this category of products also cover equipment intended for connection only to a low voltage circuit of limited power supplied by a Class 2 transformer.

Some products may incorporate service equipment devices with or without service or main switches or circuit breakers that are solely or particularly intended for use at services, either alone or in conjunction with meters, and usually embody features not required when the devices are use elsewhere than services.

Products which employ meter sockets for use with watt-hour meters and similar meters are marked with a continuous duty ampere rating and may in addition have a maximum use (intermittent) ampere rating of 125 percent or less of the continuous duty ampere rating.  A meter socket, as covered by the requirements for this category, is an assembly of wiring terminals and jaw type contacts for one or more plug-in watt-hour meters in an enclosure having provisions for securing the meter to the socket.  The requirements cover meter sockets rated (1) 300 volts alternating current or less, or 600 volts alternating current, and (2) 400 amperes maximum per meter position.

Each product is marked with the name or trademark of the (manufacturer) or vendor, a distinctive style, type, catalog or model designation, date code, wiring diagram, electrical ratings for each circuit, electrical hazard warnings, other cautionary warnings, and if employed with remote control equipment, “For Use With” markings as applicable.

These products comply with ARL requirements which include pertinent sections of the Standards for Safety, ANSI/UL 916, Energy Management Equipment and/or, ANSI/UL 869A, Reference Standard for Service Equipment and/or ANSI/UL 414, Meter Sockets.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements of the standard, and that involve a risk of fire, electric shock, or injury to persons, have been evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of the standard.  A product whose features, characteristics, components, materials, or systems conflict with specific provisions of the standard have been judged to be in non-compliance with the standard.

Only products which properly bear the ARL Listing Mark (Label) are considered Listed by ARL.


Delisted products appear with a double strike through and “DELISTED” after the report number.
Deleted/revised models for listed products appear with a single strike through.
