SKU CH-36M8-TNR5S

A 35 A, two-pole miniature breaker rated 120/240 V AC with a 10 kA interrupting capacity for QO load centres

  • 35 A rating protects 120/240 V AC circuits reliably
  • 10 kA interrupting capacity handles fault currents safely
  • Two-pole design serves single-phase loads efficiently
  • QO panelboard compatibility ensures direct fit installation
  • Reversible slotted box lugs simplify line or load wiring

QO Series 35 A Miniature Breaker

This Square D QOU235 is a two-pole miniature circuit breaker rated at 35 amps for 120/240 V AC systems. It belongs to the QO series and fits compatible QO panelboards and load centres. The unit is designed for single-phase circuits and carries a 10 kA interrupting rating at the rated voltage.

DIN Rail Mount with Reversible Lugs

The breaker mounts on a surface or DIN rail and uses slotted box lugs that accept reversible line and load connections. A toggle actuator provides manual switching. No special tools are required beyond a standard screwdriver for the lug terminals. Ensure the mounting rail is securely fastened to avoid nuisance tripping from vibration.

Verify Panelboard Series and Voltage

Confirm the existing panelboard is a QO series unit before ordering; other series will not accept this frame. Check that the circuit voltage does not exceed 120/240 V AC or 48 V DC. The 35 A rating must match the conductor ampacity and the load calculation for the branch circuit.
