Description
The Siemens CFD63B200 Molded‑Case Circuit Breaker is a robust, industrial-grade protective device from Siemens’ Sentron series, designed to deliver reliable fault interruption and continuous service in demanding electrical systems.
-
Rated Current: 200 A
-
Poles: 3-pole configuration for three-phase applications
-
Voltage Rating: 600 V AC (also suitable for 500 V DC systems)
-
Interrupting Capacity (IC): 100 kA at 600 V (200 kA at 480 V) — fuseless current-limiting capability for maximum safety
-
Trip Unit: Thermal-magnetic, non-interchangeable trip providing long-time (overload) and instantaneous (short‐circuit) protection
-
Frame Type: CFD6 / 250 A class; 40 °C ambient temperature rating
-
Connection: Bolt-on mounting; lugs are not installed (field wiring required)
-
Standards: UL 489, IEC 60947-2, CSA compliance
Key Benefits & Applications:
-
High Short-Circuit Protection: As a current-limiting breaker, the CFD63B200 restricts the magnitude and duration of fault current, helping protect downstream equipment and minimize damage.
-
Industrial and Commercial Use: Ideal for critical power systems in industrial plants, data centers, and large commercial facilities where 3-phase, high-current protection is required.
-
Durability & Reliability: Thermal-magnetic trip ensures dependable protection across a range of load and fault conditions.
-
Flexibility: With no pre-installed lugs, the breaker supports custom wiring configurations to suit your installation.
-
Safety & Compliance: Designed to meet stringent safety standards, providing peace of mind in regulatory environments.
