PXF361200GPL - 1200 Amp Circuit Breaker

PXF361200GPL - 1200 Amp Circuit Breaker

When your facility demands high-current protection you can trust, the PXF361200GPL delivers. This 3-pole, 1200 A molded case breaker from Square D excels in safeguarding industrial and commercial systems at voltages up to 600 VAC. Featuring a built-in electronic trip unit with LSIG (Long-Time, Short-Time, Instantaneous, Ground Fault) functionality, the PXF361200GPL offers finely adjustable protection settings to match your load characteristics and fault tolerance goals. Its high interrupting capacity makes it ideal for critical systems where safety and continuity are non-negotiable.

Key Features and Benefits

• Comprehensive LSIG protection: Covers long-delay (overload), short-delay, instantaneous trips, and ground fault, giving you a full spectrum of protection under one device.
• Adjustable trip parameters: Fine-tune settings to match load profiles and coordination with upstream/downstream devices.
• High interrupting capacity: Safely handles fault currents up to 125 kA at 240 V, 100 kA at 480 V, or 65 kA at 600 V (see specs).
• Bolt-on frame design: Provides secure, stable mounting for heavy-duty applications.
• Padlock capability: Includes a padlock handle to enforce lockout/tagout protocols.
• Durable build: Engineered with premium materials to resist mechanical stress, temperature cycling, and electrical wear.
