Mounts inside the PowerPacT LA, LH, or Q4 breaker accessory compartment. The 250VDC rating means it is intended for DC control circuits, not AC line-voltage tripping. Terminal torque spec of 6.2...8.9 lbf.in (0.7...1 N.m) is standard for this accessory class — use a torque screwdriver to avoid terminal damage.
