Frequently Asked Questions
Q1: What does “D Contactor” mean?
A1: “D” refers to the series designation (LC1-D) used globally for this modular, standardized AC contactor platform. It’s not a technical classification—but widely recognized in panel building for its compatibility with accessories like overload relays and mechanical interlocks.
Q2: What’s the difference between AC-3 and AC-4 duty?
A2:● AC-3: Normal starting/stopping of squirrel-cage motors (e.g., pumps, fans). Lower stress.
● AC-4: Frequent plugging, inching, or reversing (e.g., cranes, hoists). Higher electrical stress → requires more robust contacts. → CDADA LC1-D is rated for both, making it versatile.
Q3: Can I use this contactor without an overload relay?
A3: Not recommended for motor loads. The contactor only switches power—it does not protect against overloads. Always pair with a thermal or electronic overload relay for motor safety.
Q4: Are 4-pole versions available?
A4: Yes! All LC1-D models support 3P or 4P configurations—ideal for neutral-switching applications or 4-wire systems.
Q5: Why choose CDADA over other D-series contactors?
A5: CDADA offers:● Genuine IEC 60947-4-1 compliance with test reports
● Wider coil voltage range (including 415V, 480V, 600V for export)
● Consistent quality with silver-alloy contacts and arc chutes
● OEM-friendly pricing and fast sample turnaround
● Global certifications (CE) and English documentation
