Square D HGA36060 molded case circuit breaker, three-pole, grey plastic housing with lug terminals

SQUARE D

SQUARE D HGA36060 Molded Case Circuit Breaker 60A 3 Pole

SKU CH-VJN2-TQFG8

A 60 A, three-pole molded-case breaker with a 65 kA interrupting rating at 240 V AC for I-Line panelboards

  • 60 A three-pole protection for three-phase circuits
  • 65 kA interrupting rating at 240 V AC handles high fault currents
  • Thermal-magnetic trip with fixed instantaneous response
  • I-Line mounting fits compatible panelboards directly
  • 150 A frame in compact 9.73 × 4.48 × 4.8 in enclosure

Industrial Three-Pole Circuit Breaker

The SQUARE D HGA36060 is a molded-case circuit breaker rated at 60 amps with three poles for three-phase AC systems. It mounts on I-Line panelboards and uses a thermal-magnetic trip mechanism with fixed instantaneous settings. This unit suits industrial control panels and power distribution boards requiring a 150A frame size.

600V AC and 65kA Interrupting Limit

The breaker carries an AC voltage rating of 600V and a maximum AIR rating of 65kA at 240V AC. Its DC voltage rating is 250V DC. These ratings define the highest system voltage and available fault current the device can safely interrupt. Applications exceeding either value require a different protection class.

Fixed Thermal-Magnetic Trip Profile

The trip unit offers a high amp setting of 450A and a low amp setting of 800A with no adjustment range. This fixed curve determines the exact overcurrent response for motor starts and short-circuit events. Installers must verify that these non-adjustable thresholds match the coordination study for the panel.

Questions about this item

Should I select the 60 A, 3-pole version or a different ampere rating for my panel?

This breaker is a fixed 60 A, 3-pole unit in the PowerPact H frame rated 150 A. Choose it when the circuit requires exactly 60 A three-phase protection; otherwise select a different ampere rating within the same frame.

What does the 65 kA interrupting rating at 240 V AC mean for my installation?

It means the breaker can safely interrupt fault currents up to 65 kA on a 240 V AC system. Your available short-circuit current must not exceed this value at the point of installation.

How does the I-Line mounting style affect compatibility with my panelboard?

The I-Line mounting uses plug-on bus connections instead of bolt-on lugs. It fits only Square D I-Line panelboards; it will not mount in standard bolt-on or DIN-rail enclosures.
