MCSS/MCSP Current Switches
SPECIFICATION DATA
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.
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.
The MCSS and MCSP Series are covered by a five (5) year limited warranty.
