Product FAQs
7 answersHow should I use the Square D MAL36000M's 1000A current rating when selecting it?
Use the 1000A rating to evaluate the breaker against the circuit's load and protection requirements. Coordinate breaker selection with conductor sizing and the ratings of the equipment being protected.
Can this breaker be used on AC or DC circuits?
The voltage ratings are 600VAC and 250VDC. Select against the rating for the circuit's actual current type, and keep the circuit voltage within that rating.
How does the three-pole construction guide circuit selection?
This is a three-pole breaker for three-phase applications. The three poles give each phase conductor its own path through the breaker.
What does magnetic-only, instantaneous tripping mean for circuit protection?
Magnetic-only tripping responds to high current through an instantaneous magnetic trip rather than a thermal overload function. Use it where instantaneous fault protection is required, with overload protection handled separately in the circuit design.
Why would I adjust the magnetic trip setting?
The adjustable magnetic trip lets you set the current threshold that triggers instantaneous operation. Choose the setting to accommodate normal inrush while maintaining the required fault protection.
What installation work does bolt-on mounting require?
Bolt-on mounting requires mechanical fastening with bolts. Plan for secure fastening during installation rather than relying on terminal connections to hold the breaker in place.
What should I consider when terminating conductors at the lugs?
The lug terminals secure the conductors at the breaker. Proper conductor insertion and lug tightening are important for a reliable, low-resistance electrical connection.
