Ilsco SSI SSM 20 Series Manual

Designed specifically for the new construction and "bid spec" market place, the SSM
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 lightning surges as well as internally generated
transients.
The SSM series provides an effective blend of leading edge suppression design
technology, straight forward, no frills engineering and customer driven, value added
options. Specify the SSM with confidence.

Description:

Parallel connected, AC power Surge Protective Device.

Application:

Designed for use at ANSI/IEEE C62.41.1 & C62.41.2 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: 15 Years

Unit Listings:

Listed to ANSI/UL 1449 by UL (E315947), CSA (MC#241804);
UL1283* (* Type 2 SPDs only)

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.
Directly Connected All Mode - L-L, Discrete L-N (Normal Mode), and Discrete L-G,

Protection Modes:

N-G (Common Mode).

Input Frequency:

50-420 Hz (60 Hz typical)

Insertion Loss Data:

(L-N for 3Y1)
Attenuation:

EMI/RFI Filtering:

Up to 41 db normal mode, 39 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 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 = 200 kA
Nominal Discharge 10 kA (SSMC20, SSMA20); 20 kA** (SSMB20, SSMD20)
