What makes this breaker stand out

Designed for real-world installations, the HLP36020 pairs Square D’s trusted protective performance with a bolt-on mounting style that provides a secure, dependable mechanical and electrical connection. The 3-pole configuration is ideal for protecting and coordinating three-phase equipment, such as motors, drives, and control circuits, within industrial panels and service equipment.

Ideal use cases

• Maintenance and retrofit projects in factories and warehouses where a compatible 3-pole, 600V breaker is required.
• Replacement in existing panels that previously used a bolt-on style device, ensuring consistent protection without changing internal wiring schemes.
• New installations in electrical rooms or enclosures that demand a sturdy, high-availability protectivebreak for three-phase systems.

Why you should consider this specific part

The HLP36020 is not just a generic breaker. It’s a precise match for systems that rely on Square D catalog numbers and bolt-on mounting patterns. Using the part number as the compatibility reference helps ensure you’re selecting a device that aligns with your panel’s design, bus connections, and rated voltage. This specificity can reduce installation surprises and downtime when upgrading or refreshing electrical protections.

Practical guidelines for use

• Verification: Before ordering, confirm fit and ratings against your panel model and the system’s voltage and fault-current requirements. The part number HLP36020 is the best reference for compatibility in many Square D installations.
• Installation basics: Follow standard safety practices (lockout/tagout, de-energize equipment) and torque-specs appropriate for bolt-on connections to ensure a solid, long-lasting mount.
• Applications: Use in three-phase circuits where a 20A protective device is appropriate, and where the panel design supports bolt-on mounting at 600V.

With the Square D HLP36020, you gain a trusted, purpose-built solution for protecting critical equipment while maintaining flexibility for future maintenance or upgrades. Its combination of 20A protection, three poles, 600V rating, and bolt-on reliability makes it a practical choice for industrial electricians, facility managers, and professional installers looking to safeguard performance and uptime.
