Solid Core and Split Core Adjustable

Current “Status” Switches

CSS-O, CSS-C; CSP-O, CSP-C

SAFETY

WARNING

For CSS-O,C ensure that all power sources 
are disconnected and locked out before 
installation as severe injury or death may 
result from electrical shock due to contact 
with high voltage wires.

CAUTION

This product is not intended to be used for life 
or safety applications.

CAUTION

This product is not intended for use in any 
hazardous or classified locations.

INSTALLATION

Make sure that all installations are in compliance with all 
national and local electrical codes. Only qualified 
individuals that are familiar with codes, standards and 
proper safety procedures for high voltage installations 
should attempt installation. The current switches will not 
require external power, since the power for the current 
switch is induced from the conductor being monitored.

WARNING

Never rely on the LEDs to determine whether 
power is present at the current switch. The 
red LED will indicate whether the current is 
above the adjustable trip point. The green 
LED will indicate whether the current is below 
the adjustable trip point.

IMPORTANT

The current switch should be used on insulated 
conductors only!

The current switch may be mounted in any position using 
the (2) #8 x 3/4 in. (19 mm) Tek screws and the mounting 
holes in the base or snapped directly on to the 1-3/8 in. 
(35 mm) DIN rail (See Figures 1 and 2). Leave a 
minimum distance of 1 in. (25 mm) between the current 
switch and any other magnetic devices, such as 
contactors and transformers.

For applications in which the normal operating current is 
below the 0.8/2.0 Amps trip point (See Fig. 3), the 
conductor being monitored may be looped through the 
sensor 6/12 times giving you a total operating current of 
6/12 times the original current.

Example: 

A small fan operating at 0.2 Amps can be wrapped 
through the sensor 6 times to give you a total 
operating current of 1.2 Amps flowing through the 
CSS-O-A300-001. Another option is to use CSS-O-
A200-001.
A small fan operating at 0.2 Amps can be wrapped 
through the sensor 16 times to give you a total 
operating current of 3.2 Amps flowing through the 
CSP-O-A300-001. Another option is to use the 
CSP-O-A200-001.
