Why this breaker matters

When a panelboard houses critical equipment, you need protection that isn’t prone to drift or nuisance trips. The TMQD32175’s bolt‑on design provides a sturdier mechanical connection to withstand vibration and routine panel maintenance. The thermal‑magnetic trip mechanism reacts quickly to short circuits while accurately separating when overloads occur, helping prevent damage to downstream devices and extending the life of your electrical system.

Ideal use cases

• New three‑phase installations in small to mid‑sized commercial spaces with motor loads and HVAC equipment.
• Retrofits where a high‑current, bolt‑on breaker is required to match an existing GE panelboard lineup.
• Subpanel feeds or distribution points in light industrial environments where mechanical stability and reliable protection are critical.

Practical tips for installation and longevity

• Verify panelboard compatibility with GE OEM loadcenters to ensure proper trip characteristics and fit.
• Use the manufacturer’s torque specifications for bolt‑on mounting to maintain a solid, vibration‑resistant connection.
• Follow local electrical codes and safety procedures during replacement or installation, ensuring the power is off before handling any breaker.
• Consider documenting the 175 A rating and 3‑pole configuration in your panel’s protection plan to simplify future maintenance or upgrades.
