APPLICATION
The Honeywell MCSS and MCSP series current switches are
miniature “Go/No Go” current status switches designed to
provide status information on AC current supplied equipment.
The output of these switches uses a N/O solid-state switch
(more reliable than a relay) and is non-polarity sensitive.
The MCSS series is an excellent option for new installations
where the conductors can be run through the solid-core
housing before connecting the wires. The MCSP series are
ideal for retrofit applications, since their split-core design
allows them to be opened and clamped around the existing
wires without disconnecting the current being monitored. Both
of these units do not need power supplied to them as they
induce the current from the conductors being monitored.
The MCSS series has a fixed trip point of below 0.20 A while
the MCSP series has a fixed trip point of below 0.55 A. When
the current in the conductor exceeds this threshold, the sensor
will be “Closed.” The sensor will indicate “Open” when the
current is interrupted or falls to 0 A.
MCSS-F: 0.5 A Continuous, 36 VAC/VDC
MCSP-F: 0.5 A Continuous, 36 VAC/VDC
MCSS-A: 1.0 A Continuous, 36 VAC/VDC
MCSP-A: 1.0 A Continuous, 36 VAC/VDC
Status LED Indication (MCSS-A/MCSP-A models only):
Red LED: Above Trip Point
Blue LED: Under Trip Point
NOTE: Do NOT use the LEDs to indicate whether the sen-
sors have power applied to them.
Operating Frequency: 50 Hz, 60 Hz
Isolation Voltage: 2,200 VAC
Aperture (Hole) Size:
MCSS: 0.55” dia., up to 1 AWG cables
MCSP: 0.53” dia., up to 1 AWG cables
Trip Point :
MCSS-F: Fixed @ below 0.20 A
MCSP-F: Fixed @ below 0.55 A
The adjustable switches, MCSS-A and MCSP-A , include two
Status LED indicators that will indicate three states: tripped
on, current present but below trip point, and current off or
below the low end of the adjustable trip point range. Also
these adjustable current switches can be used to monitor any
change in AC current. A change in current may indicate motor
failure, belt loss/slippage, or mechanical failure. Any time one
of these events occurs, the current can significantly decrease,
thus tripping the current switch and immediately notifying the
Building Management System of the failure or problem.
Dimensions ( L x W x H ):
MCSS: 2.50" x 1.96" x 0.95"
MCSP: 2.65" x 2.35" x 0.95"
Operating Temperature Range: -30 to 60 ºC (-22 to 140 ºF)
Operating Humidity Range: 0 to 95% RH, non-condensing
