The HLP36100 SQUARE D 3P 100A 600V 50KA I LINE is a robust circuit breaker designed for three-phase applications. With a rated current of 100A and a maximum voltage of 600V, this device ensures optimal protection against overloads and short circuits. Ideal for commercial and industrial use, it provides reliable performance and safety.
The I-Line plug-in system uses a stab-on bus connection unique to Square D's I-Line panelboards and switchboards, allowing the breaker to be installed or replaced without disturbing adjacent breakers or bus connections. The HLP36100 is designed exclusively for I-Line-rated enclosures — it is not interchangeable with standard bolt-on or QO-style loadcentres. If you're unsure whether your panelboard is I-Line compatible, send us the panel model number and we'll confirm.
Availability of specific MCCB variants can vary over time as product lines are updated. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the HLP36100 has been superseded or is difficult to source through standard channels, we can often locate new, reconditioned, or equivalent stock. Contact our Calgary, Edmonton, or Vancouver counters for a quote and lead-time estimate.
Yes — with its 100A, 3-pole, 600VAC rating and 50kA interrupting capacity, the HLP36100 is well-suited for motor feeder and branch circuit protection in commercial and industrial applications under the Canadian Electrical Code (CEC). You'll want to verify that the breaker's trip characteristics (thermal-magnetic) are appropriate for the motor's full-load current and starting requirements, and that the available fault current at your panel does not exceed the 50kA interrupting rating. Our team can help you assess suitability for your application.
