Built for circuit protection, the Eaton PDG53P1200E5MN is a molded case circuit breaker with a rated current of 1200A. The breaker has 3 poles for 3-phase circuits. Its LSIG trip function provides long-time, short-time, instantaneous and ground-fault protection. These functions protect circuits against overloads, short circuits and ground faults by interrupting current when the breaker trips.
How should I use the 1200A rating when selecting the Eaton PDG53P1200E5MN?
The 1200A rated current is a starting point for matching the breaker to the circuit's load and protection requirements. Evaluate the required operating current together with the trip settings when selecting the breaker.
How do I interpret the breaker’s AC voltage ratings?
Select using the 240VAC, 480Y/277VAC or 600Y/347VAC rating that matches the circuit voltage and system configuration. The Y ratings refer to wye systems and include line-to-line and line-to-neutral voltages.
How does the 100kAIC at 480Y/277VAC interrupting rating guide selection?
At 480Y/277VAC, compare the installation's available fault current with the breaker's 100kAIC interrupting rating. The available fault current must not exceed that rating.
What protection functions does the LSIG trip offer?
LSIG means long-time, short-time, instantaneous and ground-fault protection. These functions address overloads, short circuits and ground faults, supporting protection coordination across the electrical system.
What does the adjustable electronic trip mean for setup?
The electronic trip has adjustable protection settings, allowing the breaker to be configured for the circuit's protection requirements. Choose settings as part of the system's protection coordination rather than relying on the rated current alone.
What dimensions should I use for installation layout planning?
The breaker is 16 in high, 8.25 in wide and 5.5 in deep. Use these dimensions to plan mounting space, terminal access and conductor routing.
What should I plan for with the bolt-on terminal connections?
The bolt-on terminals use bolted electrical connections. Plan conductor routing and working access so each terminal connection can be assembled and secured properly.
