HGA36150 - 150 Amp Circuit Breaker

HGA36150 - 150 Amp Circuit Breaker

The HGA36150 PowerPacT H circuit breaker is a 150-amp, 3-pole breaker built for your electrical distribution systems that need reliable thermal-magnetic protection. The breaker also uses dual-break rotating contacts to help reduce peak current during a short-circuit fault. A push-to-trip button is built into the cover, giving qualified technicians a simple way to manually trip the breaker when required. With a 150A rating, three poles, 80% continuous-current rating, ABC phase connection, HACR rating, and aluminum/copper conductor compatibility, the HGA36150 is a practical choice for replacement, maintenance, and distribution work where these exact specifications are needed.

Key Features and Benefits

• 150A, 3-pole design – Made for three-pole distribution applications that require a 150-amp breaker.
• Thermal-magnetic trip protection – Handles overload and short-circuit protection without an electronic trip unit.
• I-Line configuration – Designed for compatible I-Line equipment, with mechanical lugs on the load side.
• Dual-break rotating contacts – Helps limit peak current during short-circuit conditions.
• Push-to-trip button – Lets qualified personnel manually trip the breaker when needed.
• 80% continuous-current rating – Configured with an ABC phase connection.
• Wide conductor range – AL150HD terminals accept 14 AWG through 3/0 AWG aluminum or copper conductors.
