HGL36050 - 50 Amp Circuit Breaker

HGL36050 - 50 Amp Circuit Breaker

The HGL36050 is a 50A, 3-pole PowerPacT H circuit breaker for your compatible electrical distribution systems that need thermal-magnetic protection against overloads and short circuits. Its ratings are easy to pin down: 65 kA at 240VAC, 35 kA at 480VAC, and 18 kA at 600VAC under UL 489. This model is unit-mounted and uses mechanical lugs on both the line and load sides, with AL150HD terminals that accept copper or aluminum conductors from 14 AWG through 3/0 AWG.

Key Features and Benefits

• 50A, 3-pole design for compatible three-pole distribution applications.
• Thermal-magnetic trip protection for overload and short-circuit conditions.
• Mechanical lugs on both sides for a direct unit-mount connection.
• Dual-break rotating contacts help reduce peak current during a short circuit.
• Push-to-trip button gives qualified personnel a convenient manual trip function.
• 14 AWG to 3/0 AWG conductor range for copper or aluminum wire.
• 80% continuous-current rating for systems designed around that duty level.
