HGL36090 - 90 Amp Circuit Breaker

HGL36090 - 90 Amp Circuit Breaker

The HGL36090 PowerPacT H circuit breaker is a 90A, 3-pole thermal-magnetic breaker built for electrical distribution applications where dependable overload and short-circuit protection is essential. If you're replacing an existing breaker, the important details are easy to verify: 90 amps, three poles, H-frame construction, thermal-magnetic protection, unit-mount lug configuration, and 18 kA breaking capacity at 600VAC.

Key Features and Benefits

• 90A, 3-pole configuration: Designed for compatible three-pole electrical distribution systems requiring a 90-amp breaker.
• Thermal-magnetic trip protection: Provides protection against both sustained overload conditions and short-circuit faults.
• Line and load lugs included: Mechanical lug connections on both sides provide a straightforward unit-mount connection arrangement.
• Dual-break rotating contacts: Designed to reduce the amount of peak current that passes through the breaker during a short-circuit event.
• Push-to-trip function: An integral button on the breaker cover allows qualified personnel to manually trip the unit.
• Copper and aluminum conductor compatibility: AL150HD terminals accommodate 14 AWG through 3/0 AWG Cu/Al conductors.
• 80% continuous-current rating: Suitable for installations designed around an 80% rated circuit breaker.

Where It Works Best

The HGL36090 90A circuit breaker is well suited to compatible commercial, industrial, HVAC, and facility electrical distribution equipment requiring a three-pole, thermal-magnetic breaker with an 80% continuous-current rating. Its combination of 90A capacity, three-pole construction, 18 kA interrupting rating at 600VAC, and line/load mechanical lugs makes it particularly useful when replacing or specifying a breaker with these exact characteristics.
