Special features
Ring or Spade Lug Terminals
Two-pole protection with bolt-on mounting delivers robust mechanical stability and reliable fault interruption in dense panel layouts, enabling faster installation and safer maintenance. Ring or spade lug terminals provide flexible wiring options, simplifying field terminations and reducing wiring errors, which translates to lower labor time and higher panel reliability. HACR-rated design supports HVAC and motor control applications while meeting CSA and UL standards, ensuring compliance and smoother project approvals. The 40 A, 120/240 V rating paired with a 10 kAIC interrupt capacity minimizes nuisance trips and protects motor starters and control circuitry, driving uptime and asset longevity. Its compact 5 in length, 3 in width, and 1 in height conserve panel space, enabling higher device density without compromising protection. The 1-year warranty and documented certifications further reduce procurement risk and support lifecycle planning in manufacturing environments.
