Ilsco SSI SpecPRO CRM 4 Series Manual

Designed for mission critical applications, the CRM series is a great choice for most
small electrical panel applications. The CRM series of Surge Protective Devices
provides the features, performance and value required by discriminating specifying
engineers. This device is intended for protection of general-purpose load
applications ranging from individual equipment disconnects and sub panels to
distribution panels and service entrance locations. It is extremely effective in limiting
externally generated lightning surges as well as internally generated transients.
The CRM series provides an effective blend of leading edge suppression design
technology, straight forward, no frills engineering and customer driven, value added
options. Specify the CRM with confidence.

Description:

Parallel connected, AC power Surge Protective Device.

Application:

Designed for use at ANSI/IEEE location categories C, B and A.
Designed to protect all types of loads fed from individual
disconnects, sub-panels, distribution panels and service entrance
locations.
Warranty: 10 Years

Unit Listings:

Listed to ANSI/UL 1449 by UL (E315947), CSA (MC#241804);
UL1283

Circuit Design:

Parallel connected, hybrid circuit design incorporating both
component level thermal fusing and internal over-current fusing. All
protection circuits are encapsulated in our high dielectric compound
to promote long component life and protection from the weather and
vibration. Includes additional filtering circuitry to reduce and/or
eliminate the effects of both internal and external ringing transients.
Directly Connected L-N, (Normal Mode), and N-G (Common Mode).

Protection Modes:

(Based on Wye configuration, L-G on Delta configuration.)

Input Frequency:

50-60 Hz (60 Hz typical)

EMI/RFI Filtering:

Up to 52 db normal mode, 49 db common mode

Circuit Diagnostics:

Super Bright LED, 1 per phase, normally on. See pg. 2 for additional
diagnostics options

Connection/mounting:

#10 Wire (pre-installed), hub (pre-installed on base models, installed
at the time of installation on optional enclosures) and integral, multi-
point mounting feet.
Circuit Interrupt: Internal component level thermal fusing and patented circuit board
mounted, over-current fusing. No external over-current protection
required. (Note: National and local codes may require the use of a
circuit interrupt device(s) if conduit is added to make the wired
connection to the panel or gear). SCCR = 200kA
Nominal Discharge 10 kA (CRMA4); 20 kA** (CRMB4) (
