HGA36100

What type of circuit breaker is this?

The HGA36100 is a PowerPact H-frame moulded-case circuit breaker with thermal-magnetic protection. It is designed for electrical distribution applications and uses an I-Line plug-on mounting system.

What are its current rating and number of poles?

This circuit breaker is rated at 100 A and has three protected poles, making it suitable for compatible three-phase distribution circuits.

What protection does the thermal-magnetic trip unit provide?

The thermal element provides protection against sustained overloads, while the magnetic element responds to high short-circuit currents. The magnetic hold current is 900 A and the magnetic tripping current is 1,700 A.

What is the AC voltage rating?

The HGA36100 has a rated AC voltage of 600 V and operates at a network frequency of 50/60 Hz. Its interrupting capacity varies with the operating voltage.

What are the AC short-circuit interrupting ratings?

The interrupting ratings under UL 489 are 65 kA at 240 V AC, 35 kA at 480 V AC and 18 kA at 600 V AC. Selection should account for both the system voltage and the prospective short-circuit current at the installation point.

Which mounting arrangement does it use?

This breaker uses an I-Line plug-on arrangement for compatible I-Line panelboards and switchboards. It has an I-Line connection on the supply side and lug terminals on the load side.

What does the ABC phase designation mean?

The ABC designation identifies the breaker's phase connection arrangement within the I-Line system. This arrangement should be checked against the intended panelboard or switchboard configuration.

Which conductor sizes and materials do the load terminals accept?

The load terminals accommodate copper or aluminium conductors from AWG 14 to AWG 3/0. The specified terminal identifier is AL150HD. Conductor selection and termination must follow the applicable installation instructions.

Is this a 100% continuous-current-rated breaker?

No. The HGA36100 has an 80% continuous-current rating. This distinction must be considered when sizing the breaker for continuous loads.

Can it be used on DC circuits?

The published specifications list an interrupting rating of 20 kA at both 250 V DC and 500 V DC. Suitability depends on the DC circuit configuration and the manufacturer's required pole connection arrangement, so the voltage rating alone is not sufficient to establish compatibility.

What environmental protection does the front cover provide?

The front cover is rated IP40 to IEC 60529. This rating applies to the front cover rather than to a complete installed enclosure, so the surrounding panel must provide the protection required by the application.

What should be checked when selecting a replacement?

Check the 100 A current rating, three-pole configuration, operating voltage, interrupting capacity, thermal-magnetic trip characteristics, ABC phase arrangement and I-Line mounting compatibility. Terminal requirements and installation clearances should also be verified rather than relying on the current rating alone.
