Square D | Q1350 | Circuit Breaker | 50A | 3-Pole | 240V | 10kA | Plug-In

The Square D Q1350 is a purpose-built plug-in circuit breaker engineered for 50-amp circuits in 3-pole, 240-volt systems. It’s the reliable choice for maintenance, retrofit, and replacement projects where exact compatibility and rapid installation matter.

• Amperage: 50 A
• Poles: 3‑Pole
• Voltage: 240 V
• Interrupting Rating: 10 kA
• Style: Plug-In
• Part Number: Q1350

Why this matters: - Three-pole protection means all live conductors trip together, minimizing arc exposure and protecting multi-phase equipment. - A 10 kA interrupting rating provides solid protection against high fault currents common in commercial and industrial environments. - The plug-in design enables straightforward replacement in compatible Square D panels, reducing downtime during service or upgrades. Ideal use cases: - Panel maintenance and targeted retrofits where a precise 50 A, 3-pole, 240 V solution is required. - Replacement of a failed breaker in 3-phase, 240 V systems to restore reliable protection quickly. - Upgrading legacy installations to a modern, clearly referenced part number for easier future service. Compatibility and installation notes: - Confirm fit and ratings before ordering; the Q1350 part number is the best reference for compatibility. - This breaker is designed for Square D panels that accept plug-in Q-series breakers. Always verify your panel’s labeling and documentation to ensure a correct match. - For a clean, dependable installation, handle the breaker with the panel powered down and follow standard electrical safety practices. Who this is for: - Electricians, facilities managers, and maintenance teams responsible for reliable 3-phase protection in commercial or industrial environments. - Teams performing panel retrofits or replacements where a clearly identifiable part number and plug-in design translate to faster service windows. What makes it stand out: - Clear, single-reference part number (Q1350) simplifies ordering and compatibility checks across inventory and service records. - The combination of 50 A rating, 3-pole configuration, 240 V operation, and 10 kA interrupting capacity delivers robust protection for demanding loads. - Plug-in installation minimizes panel disturbance and supports quicker maintenance cycles without sacrificing safety or performance. Practical considerations: - Keep a spare Q1350 on hand for planned maintenance or unexpected switch-outs to minimize panel downtime. - Use the product title and specifications as your primary search anchors when shopping for replacements or upgrades to ensure correct fitment. - When in doubt, consult your panel’s documentation or a licensed electrician to confirm that your enclosure accepts plug-in Q-series breakers. Upgrade or retrofit with confidence, knowing the Square D Q1350 delivers precise compatibility, solid protection, and streamlined service for your 50 A, 3-pole, 240 V circuits.
