Product Overview

The LV426841 from Square D by Schneider Electric is a shunt trip (MX). Shunt trip serves primarily for remote, emergency off commands. It trips the circuit breaker when the control voltage rises above 70% of its rated voltage (Un). Control signals can be impulse type of ≥ 20ms or maintained control signals. An 110VAC to 130VAC shunt trip is suitable for ground fault protection when combined with a Class I ground fault sensing element. The circuit breaker must be reset locally after being tripped by shunt trip (MX). MX voltage releases comply with UL 489, CSA C22.2 number 5 and IEC 60947-2 standards. Listed for field installation per UL file E103955 and certified under CSA file 177007. Tripping by the shunt trip has priority over manual closing in the presence of a standing trip order such an action does not result in any closing even temporarily of the main contacts.
  • Control circuit voltage is 24VAC, 24VDC
  • Impulse, maintained control signal type
  • Range compatibility with PowerPact B, Compact NSXm circuit breakers
  • Impulse duration is greater than or equal to 20ms, clip-on mounting mode
  • Threshold tripping voltage is 0.7 Un during opening time
  • Continuous duty rated coil
  • Endurance is 50% of the rated mechanical endurance of the circuit breaker
  • Auxiliary connection terminal is spring
  • Response time is less than 50ms, wire stripping length is 0.31inch (8mm)
