QDF32175TS - 175 Amp Circuit Breaker

QDF32175TS - 175 Amp Circuit Breaker

When you need dependable overcurrent protection in a three-phase 240 V setup, the QDF32175TS answers the call. This 3-pole, 175 A circuit breaker delivers a high interrupting rating of 25 kA, making it ideal for demanding electrical systems that must remain safe and efficient. With its thermal-magnetic trip mechanism, the device responds accurately to both long-term overloads and sudden surges — protecting your wiring, equipment, and peace of mind. Add in its busbar connection and handy push-to-trip button, and the result is a breaker that’s easy to service, verify, and integrate into residential, commercial, or light industrial installations.

Key Features and Benefits

• High interrupting strength: Rated at 25 kA at both 208Y/120 VAC and 240 VAC, it can shut off fault currents reliably under stress.
• Thermal-magnetic trip protection: Offers two modes of defense — thermal for sustained overloads and magnetic for sudden surges — giving you responsive and precise protection.
• Push-to-trip test button: Lets you manually trip the breaker for verification checks, improving safety and maintenance convenience.
• Busbar mounting ready: Integrates smoothly into power distribution systems using busbar mounting, simplifying installation and lowering wiring hassle.
• Cycle durability: Can handle up to 1,000 loaded cycles and 5,000 no-load cycles — designed to last for years of reliable service.
