Square D | JDL36250LC | Circuit Breaker | 250A | 3-Pole | 600V | Feed-Through

Meet the Square D JDL36250LC circuit breaker—a rugged 250 A, 3-pole unit rated for 600 V with a feed-through design. Built for dependable protection and flexible downstream distribution, it’s a smart choice for maintenance, retrofit, or replacement projects where exact compatibility matters.

This 3-pole breaker is designed to manage balanced three-phase loads, delivering reliable interruption when faults occur while enabling efficient downstream feeder connections through its feed-through configuration.

Key specifications

• Amperage: 250 A
• Poles: 3-Pole
• Voltage rating: 600 V
• Feed-Through: Yes — supports downstream distribution from the main breaker

Compatibility note: Confirm fit and ratings before ordering. The part number JDL36250LC is the best reference for compatibility with your panel or system.

What sets this breaker apart

• Designed for Square D installations — the JDL form factor ensures a clean, secure fit in compatible panels and enclosures.
• Versatile for maintenance and retrofit — swap-in replacement in aging panels or when upgrading feeder protection without a full panel overhaul.
• Robust feed-through capability — streamlines downstream distribution, reducing the need for additional lugs or feeders in your wiring scheme.
• Three-phase protection — ideal for powering motors, drives, and other 3-phase loads with a compact, 3-pole design.
• Durable construction for demanding environments — engineered for reliable performance in commercial and light industrial settings.

Use cases and practical tips

• Upgrade an existing Square D installation: replace a failed or aging 3-pole 600 V feeder breaker with the JDL36250LC to restore service quickly.
• Plan a retrofit where downstream feeders must be fed directly from the main breaker via feed-through lugs, simplifying wiring and improving fault isolation.
• For new builds or service upgrades, match the 250 A rating and 600 V capacity to protect 3-phase feeders feeding heavy equipment.

This description is tailored for professionals seeking a precise, reliable Square D solution that aligns with real-world electrical installations, not generic marketing language. The JDL36250LC stands out where exact compatibility and clean downstream distribution matter most.
