Square D HLA360356 Circuit Breaker — a purpose-built, plug-in protection device engineered for dependable 3‑phase power control. With a 35A rating across three poles and a 600V nominal operating voltage, this breaker is designed to safeguard industrial and commercial electrical systems where quick, reliable fault isolation matters most.

• Part number: HLA360356
• Amperage: 35A
• Poles: 3‑Pole
• Voltage rating: 600V
• Configuration: Plug‑In
• Applications: maintenance, retrofit, and replacement in compatible panels

Designed for fast, field-ready service, the plug‑in form factor minimizes downtime by swapping breakers without rewiring. The 3‑pole configuration supports balanced three‑phase circuits, giving you clean, coordinated protection for motors, conveyors, pumps, and other multi‑phase loads commonly found in industrial setups.

Why this breaker is a smart choice

The combination of 35A protection, 3 poles, and 600V capacity is ideal for mid‑sized three‑phase distributions. This is not a generic substitute; it’s a precise match for systems that require Square D compatibility and a plug‑in mount. The HLA360356 designation is the most reliable reference when confirming fit, so always verify compatibility with your panel’s labeling or catalog before ordering.

Use cases you can count on

• Replacing a failed breaker in an existing panel to restore service quickly with minimal downtime.
• Retrofits where a 3‑pole, 600V protection device is needed to support upgraded or relocated equipment.
• Maintenance cycles for facilities with scheduled outages, ensuring stable protection without heavy rewiring.

Installation and compatibility guidance

Before ordering, cross‑check the panel’s accepted breaker type and the bus configuration. Use HLA360356 as the primary compatibility reference, and confirm the device’s ratings align with the circuit it will protect. For best results, select breakers that match the panel’s original specifications and the three‑phase load profile to ensure coordinated tripping and reliable fault isolation.

Practical tips for optimal performance

• Keep a spare HLA360356 on hand for rapid maintenance and downtime reduction.
• Document the exact panel model and the circuit being protected to facilitate future replacements.
• Handle with the system de‑energized and follow local electrical codes and safety practices during installation.

When you need dependable, purpose‑built protection that fits squarely within your 3‑phase, 600V infrastructure, the Square D HLA360356 plug‑in circuit breaker delivers precise compatibility, straightforward installation, and durable performance for demanding electrical environments.
