Power Distribution & Circuit Protection

Power Distribution & Circuit Protection covers the gear that routes electricity safely, reliably, and efficiently—from the service entrance to the final outlet. Whether you’re building a panel, upgrading a workshop, or outfitting a server rack, the right components keep loads balanced, equipment protected, and downtime low.

Explore circuit breakers (standard, GFCI, AFCI, and hydraulic‑magnetic), fuses and holders, load centers and distribution boards, transfer and disconnect switches, surge protective devices (SPD), busbars, terminal blocks, PDUs, power strips, DIN‑rail accessories, and NEMA/IEC enclosures. These products are engineered to manage capacity, isolate faults, and meet code, helping you deliver clean power with room to expand.

Benefits you can count on:
- Safety: interrupt faults quickly, prevent arc faults and ground faults, and safeguard people and gear.
- Reliability: reduce nuisance trips, add surge protection, and extend equipment life.
- Scalability: modular DIN‑rail and busbar systems simplify future circuits and retrofits.
- Compliance: options rated to NEC, UL, CSA, and IEC standards with clear AIC, voltage, and temperature specs.

Practical selection tips:
- Match ampacity, voltage, and interrupt rating to the service and fault current.
- Choose breaker curves and types for the load profile and environment.
- Pair wire gauge and lug torque with manufacturer specs; use copper or aluminum as rated.
- Specify enclosure IP/NEMA ratings for dust, moisture, and outdoor use.
- Label circuits and include lockout/tagout points for maintenance.
- Test with a multimeter or clamp meter and verify ground continuity.

From home labs to commercial facilities, smart power distribution starts with clear planning, quality components, and tidy cable management. Use our filters to compare pole counts, trip curves, AIC ratings, DIN‑rail sizes, and enclosure ratings, so you can build a safe, code‑ready system that’s easy to service and ready for growth.
