NK ASXP6-SDT-120-MS - Current Sensing Relay, ASXP-MS Series

• ASXP-MS Series
• Current sensing relay
• Range = 150-600 A
• Output Type = Single pole, double throw relay
• Power Supply = 120 VAC

ASXP-MS Series Current Switches combine a current transformer and signal conditioner into a single package. The large, easy-to-install split-core design allows for installation over existing conductors without the need to disconnect the load, even in applications where there are multiple conductors per phase. For new installations, the installation is just as easy. Just remove the top portion of the sensing ring, place the conductors inside, and snap the top back in place. The output relay energizes when the AC current through the sensing ring exceeds the adjustable setpoint, providing one contact to close and the other to open on current rise.

Crusher Monitoring

If the crusher drive draws to much current, the infeed belt can be stopped automatically, allowing the crusher to clear before restarting. The ASXP-MS also has a set of relay contacts for alarm of over or under-current conditions.

Current Sensing Switch Applications

• Detect over or undercurrent conditions before they cause break downs, or interlock one process with another.

• Detect open discharge lines.
• Sense clogged filters or blocked intake to pumps.

• Shed noncritical loads when demand reaches a set level.

Current Sensing Switch Features

• Provides both normally open and normally closed contacts.
• Compatible with most automation and control systems.

• Complete isolation between the sensor power and the controlled circuit.
• Provides a choice of failsafe* or standard operation.

• Single turn potentiometer with setpoint shown on label.
• Adjustable start delay to bypass inrush current.

• Sensing window provides ample space for bus bar, single or multiple conductors.

• Simply snap onto DIN rail or attach with screws to a panel for secure mounting.

• Accepted worldwide.
