FAQs
To install PX1-NN501, shut down power and verify the circuit is de-energized. Mount the device in a compatible panel with adequate clearance for heat dissipation, then connect the three incoming phase conductors and any required neutral per the schematic. Apply proper torque to terminal screws, secure wiring with strain relief, and re-energize only after labeling and verification.
PX1-NN501 delivers a 50 kAIC surge rating for three-phase systems with a 600 V delta configuration. This high-energy rating captures large transient currents from switching events and grid faults, protecting downstream drives, motors, and PLCs while reducing insulation stress and maintenance costs.
Yes. The PX1-NN501 is designed for three-phase protection and is well suited for motor drives, PLC racks, and panel boards. It minimizes downtime from surge events, extends equipment life, and its compact form factor eases retrofit projects without sacrificing protection quality.
Typical certifications for this class include CE marking, UL listings, and IEC standards to support global compliance and electrical safety. Always verify the exact certifications on the product labeling or datasheet for your region, as listings may vary by variant and market.
PX1-NN501 measures 2.5 in in depth, 4.8 in in height, and 2.9 in in width, weighing 1.25 lb. These compact dimensions enable easy mounting in crowded panels and retrofit scenarios, while standard three-phase mounting simplifies integration with existing switchgear.
