Square D HLA36015AABCSD 36015A 3-Pole 600 V Circuit Breaker Potential Transformer

Meet the Square D HLA36015AABCSD — a purpose-built 3-pole, 600 V circuit breaker engineered with an integrated potential transformer to streamline protection in demanding electrical environments. Built for reliability in industrial power systems, this device combines robust overcurrent protection with convenient monitoring capability in a single, compact package.

Key specifications

• Brand & Part Number: Square D HLA36015AABCSD
• Current rating: 36015 A
• Poles: 3
• Voltage rating: 600 V
• Type: 3-pole circuit breaker with integrated potential transformer

What sets it apart

Unlike standard breakers, the HLA36015AABCSD provides built-in potential transformer functionality that supports direct metering and relay protection without the need for separate transformers. This integration reduces panel wiring complexity, cuts installation time, and simplifies maintenance checks — all while delivering precise, dependable protection for three-phase systems up to 600 V. The Square D lineage ensures compatibility with compatible protection relays and switchgear, delivering a cohesive protection ecosystem for your distribution network.

Ideal use cases

• Industrial facilities with demanding 3-phase loads (motors, feeders, and processing equipment) operating at up to 600 V
• Electrical distribution panels and motor control centers where integrated monitoring is beneficial
• New installations and retrofits where streamlined protection and simplified metering are priorities

Practical benefits and insights

With its integrated potential transformer, this device supports accurate voltage and current sensing for protection relays, energy meters, and control systems. It helps you diagnose faults faster, supports timely tripping decisions, and reduces the cabling and engineering effort required for separate transformer setups. For technicians, this means cleaner panel layouts, fewer components to inventory, and a clearer path for preventive maintenance.

Installation and care tips

• Verify system voltage and phase configuration match the 600 V rating before installation
• Secure proper torque on all mounting and termination points according to manufacturer guidelines
• Store and handle in dry, clean environments to preserve contact integrity and transformer performance
• Keep spare parts and compatible relays on hand to minimize downtime during maintenance or upgrades

Engineered for reliability, precision, and streamlined protection in demanding electrical systems, the Square D HLA36015AABCSD is a strategic choice for professionals who value integrated monitoring, reduced wiring, and robust three-phase protection at 600 V.
